Abstract: With the continuous development of cars in the field of intelligence, intelligent parking technology has become the current research hotspot, and the detection of parking space is the premise of intelligent parking. Therefore, this paper proposes a parking space detection method based on machine vision. The method first carries out filtering processing, binarization processing, edge detection and other pretreatment work on the collected image, and then realizes the detection of parking space using Hough transform on the basis of the pretreatment. In the process of detection, this paper uses MATLAB software to implement the above algorithm, and builds a visual interactive interface for parking space detection based on the GUI platform. Experimental results show that the proposed method can accurately detect parking spaces, but it is also found in the process of the experiment, when the parking space area is seriously polluted, the detection effect of the detection algorithm will be reduced.
