Abstract
The invention relates to a parking spot detection method and system. The method includes: acquiring a parking lot image including one or more idle and occupied parking spots around a vehicle; inputting the parking lot image to a neural network model for image processing, to obtain center point coordinates and a center point probability of the parking spot, first coordinates and first corner point probabilities of four corner points, and offsets of the four corner points relative to the center point coordinates; calculating second coordinates of the four corner points based on the center point coordinates and the offsets of the four corner points relative to the center point coordinates; correcting the second coordinates of the four corner points by using the first coordinates of the four corner points, to obtain actual coordinates and actual corner point probabilities of the four corner points; and performing parking spot detection based on the center point coordinates and the center point probability, and the actual coordinates and actual corner point probabilities of the four corner points. According to the invention, the parking spot can be accurately detected.
