[0042] The specific implementation of the underground garage parking space detection method based on image processing of the present invention will be described in detail below with reference to embodiments.
[0043] An underground garage parking space detection method based on image processing includes the following steps:
[0044] Step 1: Detect the corner area of the parking space through the YOLOv3 deep learning model, and record the set of m corner rectangular areas detected as A={R t |t=1,2,...,m}, where R t Represents the t-th corner rectangular area; if the corner rectangular area is not uniformly illuminated, the illumination is compensated, and the image is corrected through histogram equalization;
[0045] Step 2: Use the adaptive mean method for each region R t Binarize the sub-images of;
[0046] Step 3: For each area R t The corner detection is performed on the sub-images, as follows:
[0047] Step 3.1: Use Gaussian filter to smooth the image to be processed;
[0048] Ste...
