Embodiment 1
[0018] The deep CNN-based safety belt detection method involved in this embodiment mainly includes the following steps:
[0019] (1), extract the driver's area grayscale image: collect the color image of the motor vehicle driving time that traffic checkpoint is taken, color image is changed into grayscale image; Use following computer function to grayscale in the computer system that MATLAB instrument is equipped with The grayscale image is processed to extract the image of the window area part from the original grayscale image:
[0020] carWindowAreaX1=max(plateCenterX-plateW*2, 1);
[0021] carWindowAreaY2 = max(plateCenterY-plateW, 1);
[0022] carWindowAreaX2=min(plateCenterX+plateW*2, srcImgW);
[0023] carWindowAreaY1=min(plateCenterY-plateW*4.5, srcImgH);
