The invention relates to a parking space detection method and system. The method comprises the following steps: acquiring images of a parking lot containing one or more idle and occupied parking spaces around a vehicle; inputting the parking lot image into a neural network model for image processing to obtain a central point coordinate and a central point probability of a parking space, a first coordinate and a first angular point probability of four angular points, and offset of the four angular points relative to the central point coordinate; calculating second coordinates of the four angular points according to the center point coordinates and the offset of the four angular points relative to the center point coordinates; correcting the second coordinates of the four angular points by adopting the first coordinates of the four angular points to obtain actual coordinates and actual angular point probabilities of the four angular points; and performing parking space detection based on the center point coordinates, the center point probability, the actual coordinates of the four corner points and the actual corner point probability. According to the method, the parking space can be accurately detected.
