The invention discloses an underground parking garage parking space detection method based on image processing. The method comprises the following steps that: S1: through a YOLOv3 deep learning model,detecting parking space angular point regions, and marking m pieces of detected angular point rectangular region sets as A={Rt|t=1,2,...,m}, wherein Rt shows the tth angular point rectangular region;S2: adopting an adaptive mean value method to carry out binaryzation on the subimage of each region Rt; S3: carrying out angular point detection on the subimage of each region Rt; and S4: according to S3, obtaining the angular point coordinates of all angular point regions in A, and sorting the angular point coordinates according to an abscissa. The detection method has the advantages that the interference of vehicles, rays and obstacles can be effectively eliminated, image processing is used for accurately detecting stop lines and parking space angular points so as to finish parking space detection, and the method is simple in maintenance and low in cost.
