Embodiment Construction
[0042] The specific implementation of the image processing-based underground garage parking space detection method of the present invention will be described in detail below in conjunction with the embodiments.
[0043]A method for detecting parking spaces in underground garages based on image processing, specifically including the following steps:
[0044] Step 1: Detect the corner area of the parking space through the YOLOv3 deep learning model, and record the detected set of m corner rectangular areas as A={R t |t=1,2,…,m}, where, R t Represents the t-th corner rectangular area; if the corner rectangular area is unevenly illuminated, perform illumination compensation on it, and correct the image through histogram equalization;
[0045] Step 2: Apply the adaptive mean method to each region R t The sub-image of is binarized;
[0046] Step 3: For each region R t Corner detection is performed on sub-images, as follows:
[0047] Step 3.1: smoothing the image to be process...
