Embodiment Construction
[0072] The present invention will be further described below in conjunction with the accompanying drawings.
[0073] refer to Figure 1 ~ Figure 4 , a method for detecting license plates based on a multi-task convolutional neural network, comprising the following steps:
[0074] 1) Using time-space constraints to process the acquired vehicle image data to obtain suspected fake vehicles. The suspected fake vehicles refer to suspicious vehicles detected by the screening system. The car series and body color are the same or highly similar;
[0075] 2) Use Faster R-CNN to locate and segment the image of the car body;
[0076] 3) Realize convolution sharing for the first 5 layers of convolution;
[0077] 4) Training the positioning network of the car face feature and the network for extracting the private face feature of the public face feature;
[0078] 5) Feature extraction is performed on the public face part and the private face part of the suspected license plate vehicle r...
