Embodiment 1
[0058] figure 1 It is a flow chart of the parking control method through face recognition provided by Embodiment 1 of the present invention.
[0059] refer to figure 1 , the method includes the following steps:
[0060] Step S101, collecting the video image information at the current moment and the distance information between the target object and the vehicle at the current moment;
[0061] Step S102, extracting the first position information of the human face in the video image from the video image information at the current moment, the first position information being the first angle information formed by the center of the human face and the video image;
[0062] In this embodiment, the video image information at the current moment is used as the input of the neural network algorithm, and the output is feature information, wherein the feature information includes the first position information of the face in the video image, the number of faces and the size of the face, a...

Abstract
The present invention provides a parking control method and system through face recognition, including: extracting the first position information of the face in the video image from the video image information at the current moment, the first position information being the center of the face and the video image The first angle information formed; according to the distance information of the target object at the current moment from the vehicle, the second position information of the target object relative to the vehicle is obtained, and the second position information is the second angle information formed by the target object relative to the vehicle; the first angle The information is matched with the second angle information; if the matching is successful, the steering motor is driven to rotate according to the second angle information; the distance information of the target object at the current moment from the vehicle is compared with the distance information of the target object at the next moment from the vehicle, The changing distance is obtained; the vehicle is controlled to move forward or backward according to the changing distance, and the vehicle can be automatically parked in a corresponding parking space through face recognition, thereby improving parking efficiency.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a parking control method and system through face recognition. Background technique [0002] At present, the driver controls the vehicle to reverse or park in place, and needs to get out of the vehicle frequently to observe the surrounding conditions before returning to the vehicle to continue driving, or for vehicles with automatic parking functions, automatic parking cannot In the three-dimensional garage environment, the vehicle needs to be poured into the parking bay, and the automatic parking cannot recognize the parking bay, which leads to the difficulty of parking for the driver. Contents of the invention [0003] In view of this, the object of the present invention is to provide a parking control method and system through face recognition, which can automatically park a vehicle to a corresponding parking space through face recognition, thereby improving parking e...
