Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Fig. 1 is a block diagram of a system 100 for recognizing the opening of a tailgate according to an embodiment of the invention. As shown in fig. 1, the system 100 is adapted for use with an automobile 170, the automobile 170 having an automobile tailgate 172, the system 100 including an automobile sensor 110, a camera 120, a processor 130, and an automobile radar 140.

For example, the car sensor 110 may be a wireless sensor, the camera 120 may be a car rear lens and/or surround view camera, the processor 130 may be a central processing unit, the car radar 140 may be a car anti-collision radar, and the car tailgate 172 may be an electric car tailgate. The processor 130 is electrically connected to the car sensor 110, the camera 120 and the car tailgate 140.

In use, the processor 130 determines whether the vehicle sensor 110 senses the wireless vehicle key 112. If the car sensor 110 senses the wireless car key 112, it represents that the user has moved to the car 170.

After the car sensor 110 senses the wireless car key 112, the processor 130 determines whether a human face is detected by the camera 120. If a human face is detected, it represents that the user is facing the car 170. It should be noted that, since the car sensor 110 senses that the wireless car key 112 has indirectly confirmed the identity of the user, the present embodiment may only perform face detection, and further face recognition is not needed, so as to reduce the determination time.

When a human face is detected by the camera, the processor 130 determines whether the range of the human face reaches a preset opening standard. For example, if the ratio of the face area to the whole frame exceeds a predetermined ratio (e.g., 50%), the predetermined turn-on criterion is reached, which indicates that the user is facing the car 170 in a close range. It should be understood that the above preset opening criteria are only exemplary and not intended to limit the present invention, and those skilled in the art can select the suitable preset opening criteria according to the practical application.

When the range of the face reaches the predetermined opening standard, the processor 130 determines whether two eyes are detected by the camera 120. If both eyes are detected, it represents that the user is looking at the car 170. For example, the processor 130 determines whether the eyes are open or not according to the eye aspect ratio, and determines the fixation time (i.e., the duration of the eye opening) in a counting manner, and if the fixation time exceeds a predetermined time, the processor 130 determines that both eyes are detected.

After detecting both eyes with the camera 120, the processor 130 may open the tailgate 172.

In this embodiment, after detecting the two eyes by the camera 120, the processor 130 determines whether the vehicle distance needs to be adjusted by the vehicle radar 140. When the automobile radar 140 is used to determine that the distance needs to be adjusted, the processor 130 opens the automobile tail gate 172 after the distance is automatically adjusted accordingly.

For example, when the car radar 140 detects that the distance from the car 170 to the obstacle behind the car is less than the preset distance, it is determined that the car distance needs to be adjusted, at this time, the processor 130 moves the car 170 forward to make the distance from the car 170 to the obstacle behind the car greater than the preset distance, and then the processor 130 opens the car tailgate 172. In practice, the predetermined distance may be the minimum distance required to open the tailgate 172.

On the contrary, when the vehicle radar 140 determines that the vehicle distance does not need to be adjusted (e.g., the vehicle radar 140 detects that the distance from the vehicle 170 to the obstacle behind the vehicle is greater than or equal to the predetermined distance), the processor 130 directly opens the vehicle tailgate 172.

In this embodiment, after the trunk door 172 is opened, the processor 130 turns off the camera 120, thereby saving power and system resources.

For further description of the system 100 for recognizing the opening of the car tailgate by using an image, please refer to fig. 1 to 2, and fig. 2 is a flowchart of a method 200 for recognizing the opening of the car tailgate by using an image according to the present embodiment. As shown in fig. 2, the method 200 includes steps S201 to S207 (it should be noted that, the steps mentioned in the present embodiment, except for the specific description of their sequence, can be performed simultaneously or partially simultaneously, with their sequence being adjusted according to actual needs).

In step S201, the car sensor 110 performs sensing. Next, in step S202, it is determined whether the car sensor 110 senses the wireless car key 112. After the car sensor 110 senses the wireless car key 112, in step S203, it is determined whether a human face is detected by the camera 120. When a human face is detected by the camera 120, in step S204, it is determined whether the range of the human face reaches a predetermined opening standard. When the range of the face reaches the preset opening standard, in step S205, it is determined whether two eyes are detected by the camera 120. After detecting both eyes with the camera 120, the trunk door 172 is opened in step S206. After the back door 172 is opened, the camera 120 is turned off in step S207.

Fig. 3 is a flowchart of a method 300 for recognizing the opening of a tailgate by an image according to another embodiment of the present invention. As shown in fig. 2, the method 300 includes steps S301 to S310 (it should be noted that, the steps mentioned in this embodiment, except for the specific description of their sequence, can be performed simultaneously or partially simultaneously, with their sequence being adjusted according to actual needs).

In step S301, the car sensor 110 performs sensing. Next, in step S302, it is determined whether the car sensor 110 senses the wireless car key 112. After the car sensor 110 senses the wireless car key 112, in step S303, it is determined whether a human face is detected by the camera 120. When a human face is detected by the camera 120, in step S304, it is determined whether the range of the human face reaches a predetermined opening standard. When the range of the face reaches the preset opening standard, in step S305, it is determined whether two eyes are detected by the camera 120. After detecting both eyes with the camera 120, the car radar 140 is turned on in step S306. Next, in step S307, it is determined whether the vehicle distance needs to be adjusted by the vehicle radar 140. When the automobile radar 140 is used to determine that the distance needs to be adjusted, in step S308, the distance is automatically adjusted accordingly. Next, in step S309, the tailgate 172 is opened. Then, in step S310, the camera 120 is turned off.

On the contrary, when the automobile radar 140 determines that the distance does not need to be adjusted (e.g., the automobile radar 140 detects that the distance from the automobile 170 to the obstacle behind the automobile is greater than or equal to the preset distance), the automobile tailgate is directly opened in step S209. Then, in step S210, the camera 120 is turned off.

Compared with the prior art, the embodiment of the invention judges whether the automobile sensor senses the wireless automobile key; after the automobile sensor senses the wireless automobile key, whether a human face is detected by the camera is judged, when the human face is detected by the camera, whether the range of the human face reaches a preset opening standard is judged, when the range of the human face reaches the preset opening standard, whether double eyes are detected by the camera is judged, after the double eyes are detected by the camera, the automobile tail gate is opened, namely, the automobile camera is used for capturing a user picture, and whether the tail gate is opened is judged by an image identification mechanism, so that the probability of misjudgment is reduced, and the convenience is improved.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
