Detailed Description

The moving object is provided with a power system, and the purpose of controlling the movement of the moving object is achieved by controlling the power system. In one embodiment, the rotational speed or rotational direction of the motor may be adjusted by an electronic governor to control the moving object to move at different speeds or in different directions. For example, in unmanned vehicle, the rotation through control motor drives the rotation of wheel, can control unmanned vehicle forward, backward with different speed motion, equally to unmanned aerial vehicle, the rotation through control motor drives the rotation of screw to control unmanned aerial vehicle moves with different speed on different directions.

The cloud platform can be arranged above or below the moving object or on the side surface as required, and the camera device can be fixed on the cloud platform. The holder can rotate in one direction, or two directions, or three directions, or more directions, so as to shoot the environment image in different directions when the moving object is static or in the moving process. In one embodiment, the pan/tilt head can rotate on the pitch axis, roll axis, and yaw axis, thereby adjusting the shooting direction of the mounted camera.

As shown in fig. 1, which is a schematic flow chart of a rotation control method of an image pickup apparatus according to an embodiment of the present invention, the rotation control method according to an embodiment of the present invention may be implemented by a controller disposed in a moving object, or the moving object may acquire related information data and transmit the data to a remote controller at a user end, and the data is calculated by the remote controller and then returned to the moving object or directly controls a pan/tilt head. The method of an embodiment of the present invention includes the following steps.

S101: and acquiring the motion direction of the camera device. In one embodiment, the direction of motion may be determined from data sensed by an acceleration sensor, a gyroscope. In one embodiment, the movement direction may also be determined based on data sensed by a GPS (Global Positioning System) sensor, specifically, based on a change in position, and in one embodiment, the movement direction may also be determined based on a distance sensor, specifically, based on a distance of a moving object from a reference object or an obstacle, for example, if the distance sensor detects that the aircraft is closer to the ground, the aircraft may be determined to move downward.

The sensor can be directly arranged on the camera device and used for sensing the motion data of the camera device and determining the motion direction of the camera device. In one embodiment, since the image capturing device is fixed on the pan/tilt head, and the moving object itself is provided with a corresponding sensor for sensing the movement of the moving object, the movement direction of the moving object can be obtained and taken as the movement direction of the image capturing device.

S102: if an obstacle is detected to exist in the moving direction and the relation between the camera device and the obstacle meets a collision condition, a rotation control instruction is sent out; the rotation control instruction is generated according to the movement direction and the lens orientation of the camera device, the rotation control instruction is used for controlling the camera device to rotate, and after the camera device rotates, the lens orientation of the camera device is different from the movement direction. In one embodiment, obstacles, such as the ground, walls, or some protruding rocks, other moving objects, etc., may be sensed by a sensor, such as a visual sensor. In one embodiment, an object within a preset distance range from the moving object may be referred to as an obstacle through a combination of the ultrasonic sensor and the camera.

When the relationship between the image pickup device and the obstacle satisfies the collision condition, it may be considered that the image pickup device continues to move in the movement direction, which may cause the image pickup device to collide with the obstacle, or that the lens of the image pickup device may collide with the obstacle, so that the lens may be damaged. In one embodiment, the meeting of the collision condition may mean that the distance between the image pickup device and the obstacle is smaller than a preset distance threshold, or the distance between the image pickup device and the obstacle is within a preset distance range threshold. In one embodiment, the lens orientation of the lens of the image pickup device at the moment can be judged, and if the lens is oriented to the obstacle and the distance between the image pickup device and the obstacle is smaller than a preset distance threshold value or is within a distance range threshold value, the collision condition is considered to be met.

In one embodiment, the rotation control instruction is mainly used to control a pan/tilt head disposed on the moving object to rotate on a pitch axis so as to control the image pickup device to rotate, and after the rotation, a lens orientation of the image pickup device is different from the movement direction. In one embodiment, the rotation control instruction is used for controlling the holder on the moving object to rotate on a yaw axis so as to control the camera device to rotate, and after the rotation, the lens orientation of the camera device is different from the movement direction.

Next, turning control of the image pickup apparatus according to the embodiment of the present invention will be described with reference to fig. 2 and 3. Fig. 2 illustrates an aircraft as an example, and the same manner of implementing the rotation control of the imaging device in a moving object such as a robot or a submersible that can move in the horizontal direction and the vertical direction is implemented. Fig. 3 illustrates an unmanned vehicle as an example, and the same manner of controlling the rotation of the imaging device is realized in a moving object such as a horizontally movable robot, a horizontally movable aircraft, or a horizontally movable submersible vehicle.

In fig. 2, the aircraft is capable of moving in a horizontal direction or an approximately horizontal direction based on a preset course or based on control by a remote controller. The lower part of the aircraft is provided with a pan-tilt which can rotate at least on the pitch axis and also on the pitch axis and yaw axis. In other embodiments, a pan/tilt head may also be provided in the upper part of the aircraft. As shown in fig. 2, a control device (e.g., a flight controller) provided on an aircraft 201 detects that the aircraft 201 is currently moving in a moving direction 202, and at a position a, detects that there is a wall in the moving direction 202, which is regarded as an obstacle 203, based on data of a sensor such as a visual sensor, and the lens orientation 205 of a camera 204 fixed on a pan/tilt head of the aircraft is also oriented toward the obstacle 203. In the process of flying to the obstacle 203, there may be some protrusions on the obstacle 203 such as a wall, so that the lens of the image pickup device 204 may collide with the protrusions to damage the lens.

During the continuous flight, the control device determines that the relationship between the camera and the obstacle 203 meets the collision condition, and the control device mainly can sense and determine the distance d between the camera and the obstacle 203 through a distance sensor or directly uses the distance between the aircraft 201 and the obstacle 203 as the distance d. In fig. 2, when the aircraft 201 flies to the point B, it is determined that the distance d reaches a preset distance threshold (or is smaller than the preset distance threshold), and it is further determined that the relationship between the image pickup device and the obstacle satisfies the collision condition, the control device generates a rotation control instruction, and sends the rotation control instruction to the pan/tilt head, so as to control the pan/tilt head to rotate. The rotation control command controls the pan/tilt head to rotate on the pitch axis (in other embodiments, the pan/tilt head may also rotate on the yaw axis) from the point B, so that the lens of the imaging device is no longer facing the obstacle 203. As shown in fig. 2, after the aircraft 201 flies to reach the position C, the pan/tilt head rotates on the pitch axis to a specified angle, which is 90 degrees with respect to the moving direction or the lens orientation of the camera before rotation, or any angle within an angle range of about 90 degrees (5 degrees or 10 degrees left and right). After the lens is rotated according to the specified angle, the direction of the lens of the camera device is different from the moving direction.

In fig. 3, the pan/tilt head is provided in the front of the head of the unmanned vehicle 301, the lens of the imaging device 302 faces 303 a wall as an obstacle 304, and the direction of movement of the unmanned vehicle 301 is 305. The unmanned vehicle 301 determines the obstacle 304 at the position D, determines that the distance D between the camera device 302 and the obstacle 304 at the position E meets the collision condition, generates a rotation control instruction to start controlling the pan-tilt to rotate upwards, so as to drive the camera device 302 to rotate, and at the position F, the new lens orientation 303 of the camera device 302 faces the sky after rotating through the pitch axis instead of facing the obstacle 304.

In one embodiment, a moving object such as an aircraft is capable of moving in a vertical direction or an approximately vertical direction based on a preset course or based on control by a remote controller. Particularly, when a landing command sent by a remote controller is executed or the aircraft needs to automatically land due to the fact that the battery level of the aircraft is low and the like, the aircraft can fly downwards in the vertical direction. As shown in fig. 4, which is a schematic flow chart of another rotation control method of an image capturing apparatus according to an embodiment of the present invention, the rotation control method according to an embodiment of the present invention may be implemented by a controller disposed in a moving object, or the moving object may acquire related information data and transmit the data to a remote controller at a user end, and the data is calculated by the remote controller and then returned to the moving object or directly control a pan/tilt head. The method of an embodiment of the present invention includes the following steps.

S401: and when a landing instruction is acquired, acquiring the distance between the aircraft and a landing position area. As described above, the landing command may be a command sent by the remote controller to request the aircraft to land on the ground, or may be a landing command automatically generated when it is detected that the battery of the aircraft is low or it is not possible to normally receive a signal from the ground. After the landing command is acquired, the determination of the distance between the aircraft and the landing location area is started. If it is determined that the height of the aircraft when the aircraft obtains the landing instruction is higher according to sensors such as a barometer, the distance between the aircraft and a landing position area can be detected after the aircraft lands at a certain height, wherein the landing position area mainly refers to a certain area on the ground, the position area may refer to different positions due to unstable flight of the aircraft or external weather (such as strong wind weather) in the landing process of the aircraft, and the area which can detect the distance at present is used as the landing position area by the control equipment.

The distance between the image pickup device and the landing position area may be detected by a sensor such as ultrasonic waves or radar, or the distance between the aircraft and the landing position area may be directly sensed by various sensors provided on the aircraft, and the distance between the aircraft and the landing position area may be used as the distance between the image pickup device and the landing position area.

S402: if the acquired distance meets the collision condition, a rotation control instruction is sent out; the rotation control instruction is used for controlling the camera shooting device to rotate, and after the camera shooting device rotates, the direction of the lens of the camera shooting device is different from the movement direction of the lens when the landing instruction is executed. The acquired distance satisfying the collision condition means that: and the lens of the camera device faces the landing position area, and the acquired distance is smaller than the distance threshold value or within the range of the distance threshold value.

When the acquired distance meets the collision condition, it can be considered that the camera device may collide with the ground in the landing process of the camera device, or the lens of the camera device may collide with the ground, so that the lens may be damaged.

In one embodiment, the aircraft is provided with a cradle head, and the camera device is fixed on the cradle head; the rotation control instruction is used for controlling the holder to rotate on the pitching shaft so as to control the camera device to rotate, and after the camera device rotates, the direction of a lens of the camera device is different from the movement direction. Or in one embodiment, the aircraft is provided with a tripod head, and the camera device is fixed on the tripod head; the rotation control instruction is used for controlling the tripod head to rotate on a yaw axis so as to control the camera device to rotate, and after the camera device rotates, the direction of a lens of the camera device is different from the movement direction.

As shown in fig. 5, the rotation control process of the camera device during the landing of the aircraft is shown. The aircraft 501 is provided with a pan/tilt head which can rotate on a pitch axis, a yaw axis and a roll axis, the camera 502 is fixed on the pan/tilt head, and the current shooting direction of the camera 502 is shooting downwards. At altitude X, aircraft 501 receives a landing control command and begins to execute a landing. At this time, a control device (e.g., flight controller) on the aircraft 501 may detect the flying height in real time, and when the height d is less than a certain height threshold value, start detecting the distance to the ground based on a sensor such as an ultrasonic wave. Of course, the distance to the ground can be detected in real time directly based on the sensors such as the ultrasonic waves, even if the distance data cannot be acquired due to the high height, the distance to the ground can be continuously detected in real time based on the sensors such as the ultrasonic waves until the distance to the ground is detected.

When the aircraft lands at the height Y, the control equipment determines that the distance d between the aircraft and the landing position area meets the collision condition, generates a rotation control command, sends the rotation control command to the holder and controls the holder to rotate. The rotation control command controls the pan/tilt head to rotate on the pitch axis from the position Y so that the lens orientation 503 of the camera device no longer faces the ground, for example, the pan/tilt head may be controlled to return to the neutral position so that the lens orientation of the camera device is horizontal on the pitch axis and parallel to the ground. As shown in fig. 5, at some small height after the aircraft 501 is fully landed or before landing, the pan head is rotated on the pitch axis to a specified angle, which is 90 degrees relative to the direction of motion or the orientation of the lens of the camera before rotation, or any angle within an angular range of about 90 degrees (5 degrees or 10 degrees left and right). After the lens is rotated according to the specified angle, the direction of the lens of the camera device is different from the moving direction.

By adopting the embodiment of the invention, the movement of the moving object can be evaluated, the lens orientation of the camera device is controlled when the collision condition is met, the lens of the camera device can be prevented from being damaged in the moving process of the moving object to a certain extent, and the automatic and intelligent requirements of users on lens package protection are met.
