It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a method for prompting a parking space by an elevator, the elevator and a storage device, and as shown in figure 1, the method for prompting the parking space by the elevator comprises the following steps:
step S100: the parking lot camera captures images of the vehicle and the driver's face on the parking space.
Specifically, the position of the parking space of the parking lot is provided with a camera, the camera can be shared by a row of parking spaces, the camera mainly shoots a vehicle image and a driver face image on the parking space, and the shot image is transmitted to the processor for algorithm processing.
And S200, identifying license plate information in the vehicle image.
In specific implementation, the vehicle image is transmitted to the processor, and the image is processed through a processor program to identify the license plate number of the vehicle.
And step S300, identifying the facial feature information in the facial image.
In specific implementation, the driver face image is transmitted to the processor, and the image is processed through a processor program to identify the driver face feature information.
As shown in fig. 2, preferably, the step S300 specifically includes:
step S310 detects at least one keypoint in the driver face image to be recognized.
Step S320 performs an enlargement and/or reduction process on the driver face image to be recognized to obtain a plurality of images of different sizes of the driver face image to be recognized.
Step S330 is to extract, for each of the plurality of images with different sizes, a feature of a predetermined region including each of the keypoints as a feature of each of the keypoints on each of the images.
Step S340 generates a feature of each of the plurality of images as facial feature information according to the feature of each of the plurality of key points on each of the plurality of images.
When the method is specifically implemented, one or more key points of a driver face image are detected, the features of a specific area near the key points are obtained through a plurality of images with different sizes of the face key points, the features of each key point are generated according to the features of the key point feature area, and the features of each key point are used as the face feature information of the driver.
The more key points detected, the more accurate the detection result.
And S400, associating and storing the license plate information, the parking space position and the facial feature information.
When the system is specifically implemented, the processor associates and stores the acquired license plate information, the corresponding parking space information and the facial feature information of the driver.
And step S500, acquiring the facial feature information of the person who wants to take the elevator to the parking lot.
When the method is specifically implemented, a camera is arranged in the elevator car or a monitoring camera arranged in the elevator car is adopted to photograph the face of a person who wants to take the elevator to the parking lot, and the face image of the person who wants to take the elevator to the parking lot is detected and analyzed by adopting a method for identifying the face feature information in the driver face image.
