Before the embodiments of the invention of the present application are introduced, the concept of the present application will be briefly described: this application mainly can adjust the baseline distance between two cameras through setting up drive module, can realize the regulation of range finding precision to the cost ratio is lower.

Referring to fig. 1, the present application provides a vehicle warning device disposed behind a vehicle, including: two cameras 110, a driving module 120, an image processing module 130 and an alarm module 140.

The two cameras 110, the cameras 110 are respectively arranged at two sides of the rear part of the vehicle; a driving module 120 connected to the cameras 110, for controlling the cameras 110 to translate along the base line between the cameras 110 to adjust the base line distance between the cameras 110; the image processing module 130 is connected with the camera 110, and is used for processing the image obtained by the camera 110 and judging whether a dangerous situation occurs behind the vehicle; and an alarm module 140 connected to the image processing module 130 for alarming the user when a dangerous situation is present.

Further, referring to fig. 2, the driving module 120 includes: a connecting arm connected to the camera 110, and a motor driving the connecting arm.

Further, the driving module 120 further includes: an angle adjusting unit 124 connected between the camera 110 and the connecting arm, for adjusting an angle of the camera 110. Thus, the camera 110 can rotate a certain angle in the up, down, left and right directions, so that the shooting range of the camera 110 is wider and more flexible.

Further, referring to fig. 3, the driving module 120 includes: the camera module comprises a fixed seat 121 connected with the camera 110, a slide rail 122 for slidably connecting the fixed seat 121, and a motor 123 for driving the fixed seat to move on the slide rail. Specifically, two fixing bases 121 set up respectively in the both sides of slide rail 122, and camera 110 fixes on fixing base 121, and motor 123 sets up in the centre of slide rail 122, and motor 123 passes through the conveyer belt with fixing base 121 to be connected, and motor 123 drive conveyer belt work, and the conveyer belt drives fixing base 121 and removes along two camera 110's baseline direction.

Further, the driving module 120 further includes: and an angle adjusting unit 124 connected between the camera 110 and the fixing base, for adjusting an angle of the camera 110. Thus, the camera 110 can rotate a certain angle in the up, down, left and right directions, so that the shooting range of the camera 110 is wider and more flexible.

In this embodiment, the image processing module 130 includes an image recognition chip, and can perform synthesis processing on image data obtained by the camera and recognize a dangerous situation in the image.

Further, the alarm module 140 includes: at least one of a sound player 141, an indicator light array 142, and a display 143.

Further, in this embodiment, the sound player 141 may be configured to broadcast the warning information, for example, when the alarm module 140 detects that there is a vehicle distance from the left rear of the vehicle is relatively close and the speed exceeds a preset value, the sound player 141 plays a voice: "please note the left rear of the vehicle".

Further, the indicator array 142 includes indicator lights respectively corresponding to the left and right rear directions of the vehicle, wherein when it is determined that a dangerous situation occurs in the corresponding direction of the vehicle, the corresponding indicator light is controlled to emit light to remind the dangerous situation in the corresponding direction. For example, when the overtaking situation occurs at the left rear of the vehicle, the indicator light corresponding to the left rear is lighted, so that the user can simply and directly know that the dangerous situation may occur at the left rear.

Further, the display screen 143 can perform early warning by displaying human-computer interaction, specifically, the image acquired by the image processing module 130 through the display screen 143 can display a rear simulated vehicle condition, and when a vehicle with a fast speed and a short distance appears behind, the user is reminded through the interactive interface.

In this embodiment, the sound player 141, the indicator light array 142, and the display screen 143 may be in wireless communication with the image processing module 130, and the image processing module 130 sends the processed image to the sound player 141, the indicator light array 142, and the display screen 143 in a wireless manner.

Further, the vehicle early warning device further comprises: and the sensor module is connected with the driving module 120 and is used for controlling the driving module 120 to work to adjust the camera 110 to move a preset distance when the current vehicle scene is monitored to be a preset scene.

In this embodiment, the sensor module includes at least one of a weather sensor, a temperature sensor, a humidity sensor, a light sensor, and a GPS unit. The sensor can deal with the change of a scene in the driving process, and shooting parameters are adjusted according to the change of the scene, so that early warning is more accurate.

For example, when the weather sensor senses that the weather is rainy, if the camera 110 maintains a longer shooting depth, the shooting may not be clear enough, so that the baseline distance between the two cameras 110 can be adjusted, the shooting depth is closer, and the shooting can be clear.

For another example, if the vehicle is shot at night, the camera 110 may not obtain a clear image if the rear vehicle is far away from the vehicle, which may cause the warning module 140 not to accurately warn the rear vehicle of a dangerous situation.

For another example, when the vehicle is driving in an urban area, the GPS unit locates the vehicle, and if it is determined that the position of the vehicle is on an urban road section, it is necessary to identify a distance that is a little bit closer to the rear of the vehicle, so that a fusion error can be reduced, and thus the distance of the base line needs to be adjusted, and the distance between the two cameras is also adjusted to be shorter, so that the shooting is clearer. And if the GPS unit is positioned when the vehicle runs on the highway, the distance of the base line needs to be adjusted to be longer because the distance between the vehicles on the highway is longer, and the distance between the two cameras is also adjusted to be longer, so that a long-distance scene can be shot, and the early warning requirement of running on the highway is met.

Therefore, by providing a sensor for sensing a scene, the camera 110 can shoot according to the actual scene, which can help to optimize the shooting of the camera 110.

Further, the vehicle early warning device further comprises: and an adjusting module 150, connected to the driving module 120, for controlling the driving module 120 by a user to adjust the baseline distance between the two cameras 110.

In this embodiment, the adjusting module 150 includes an adjusting knob, and the user can control the driving module 120 to drive the cameras 110 to move a set distance along the baseline between the cameras 110 by twisting the adjusting knob. Depth according to the formula of binocular camera imaging

Wherein f is the focal length, b is the baseline distance, and d is the parallax obtained by matching the left and right images, i.e., if the distance of the baseline between the two cameras 110 is related to the depth, therefore, gears can be arranged on the adjusting knob, and different gears correspond to different visual depths, and the user can adjust different visual depths through the adjusting knob.

Further, the adjusting module 150 may be wirelessly connected to the driving module 120, or the adjusting module 150 may be disposed at a position convenient for a user, such as near a steering wheel or near a car, and after the adjusting module 150 is wirelessly connected to the driving module 120, the user outputs a wireless signal through the adjusting module 150 to adjust a baseline distance of the camera 110 installed behind the vehicle. In other embodiments, the adjustment module 150 may also be wired to the driver module 120.

Further, the adjustment module 150 can also control the adjustment angle adjustment unit 124. That is to say, the adjusting module 150 may control the driving module 120 to operate to adjust the baseline distance, and after the adjustment of the baseline distance is finished, the adjusting module 150 may control the angle adjusting unit 124 to adjust the shooting angle of the camera.

Further, the vehicle early warning device includes: and the wireless communication module 170 is connected with the image processing module 130, and comprises a bluetooth module, a wifi module and a 2G/3G/4G module, and is used for transmitting the image obtained by the image processing module.

Referring to fig. 4, the present application provides a vehicle warning system, which includes: the car machine 220 is connected to the vehicle early warning device 210, and the car machine 220 is used for controlling the vehicle device.

In this embodiment, the car machine 220 can connect various devices in the vehicle, and the early warning to the rear vehicle through the vehicle early warning device 210 can realize the control application, for example, the car machine 220 can connect the door control unit, and when the vehicle early warning device 210 finds that the rear vehicle is coming, the car machine 220 sends out the control signal of closing the door, and the door control unit keeps the door closed after receiving the control signal. Therefore, the safety accident caused by the fact that passengers or drivers who get off the vehicle open the vehicle door and do not pay attention to the vehicle can be prevented when the vehicle comes from the rear.

Further, the vehicle early warning device 210 may also transmit the image obtained by the image processing module 130 to a display screen of the vehicle, or transmit the image obtained by the image processing module 130 to a terminal.

The working principle of the present application will be explained with reference to fig. 1 to 4.

This application at first needs to adjust the baseline distance of two cameras, and the user can set up manual regulation measuring depth, also can set up automatically regulated measuring depth.

The manual adjustment of the measuring depth is specifically as follows: the user can adjust the measured depth through the adjusting module 150, or through the adjusting knob, after the user selects the gear of the adjusting knob and sets the angle of the angle adjusting unit, the adjusting module 150 sends an adjusting signal to the driving module 120, the driving module 120 controls the cameras 110 to move along the base line between the two cameras 110 according to the driving signal output by the adjusting module 150, and after the movement is finished, the shooting angle of the cameras 110 is continuously adjusted according to the driving signal. After the adjustment is completed, the camera 110 captures an image, and the image processing module 130 analyzes and processes the acquired image to determine whether a dangerous situation occurs behind the vehicle, for example, a situation that the speed of the vehicle is too high and the vehicle may overtake the vehicle occurs behind the vehicle. When the image processing module 130 determines that a dangerous situation occurs, the alarm module 140 broadcasts the dangerous situation through the sound player 141, the indicator light or the display screen 143.

The way of automatically adjusting the measuring depth is generally consistent with the above-described case of manual adjustment, with the difference that: when the mode of automatically adjusting the measurement depth is set, the current scene is sensed by the sensing module 160, for example, when the current environment sensor and the light sensor sense that the current scene is rainy day or at night, the corresponding adjustment measurement depth is shorter, so that the shooting is clearer. For another example, when the GPS unit senses that the current position of the vehicle is on the highway, the distance between the vehicles on the highway is longer, and the distance between the two cameras is longer, so that a long-distance scene can be shot.

After the distance of the baseline is adjusted, the user can also adjust the shooting angle of the camera 110.

When the base line distance and the shooting angle are adjusted well, the image processing module acquires the shot image, identifies and judges the image, and controls the alarm module to give an alarm when the dangerous situation appears in the image, for example, the situation that a rear vehicle needs to accelerate to overtake or the distance between two vehicles is relatively short and the rear-end collision is likely to happen.

The alarm mode of the alarm module is mainly as follows: sound, pilot lamp, display screen. Remind the user through sound, also can be through setting up the pilot lamp that corresponds, for example left side pilot lamp is corresponded in the left back, and the right back corresponds the right side pilot lamp and reminds the user. Of course, the user may also be reminded by displaying the simulated scene on the display screen, for example, a video picture simulating the passing behind reminds the user of the passing behavior.

The beneficial effect of this application lies in: through setting up the both sides that two cameras are located the vehicle rear respectively, drive module control camera carries out the translation along the baseline between the camera in order to adjust the baseline distance between the camera, when image processing module judges that the rear of vehicle appears dangerous situation, alarm module reports to the police to the user, can make the precision of range finding adjust according to the condition of reality like this to the cost ratio is lower.

The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. It will be apparent to those skilled in the art from this disclosure that many more simple derivations or substitutions can be made without departing from the inventive concepts herein.
