Rapid parking space detection method based on deep learning

Abstract

The invention relates to a rapid parking space detection method based on deep learning, belongs to the technical field of driving, and is used for solving the problems of poor parking space detectionenvironment adaptability and large model calculation amount, and the method comprises the steps: an offline step: offline collecting image data including parking spaces, and establishing a training and verification data set; training, evaluating and optimizing a neural network model, wherein the neural network model is used for performing semantic segmentation on parking space sidelines in the image data; an online steps: collecting image data containing parking spaces online, carrying out semantic segmentation on parking space side boundary lines through a trained neural network model to obtain parking space side boundary masks, carrying out fitting, clustering and combination on the obtained side boundary masks, and obtaining a geometrical shape composed of the side boundaries; and according to a set shape discrimination condition, screening the geometrical shape to determine the parking space. The method is high in environmental adaptability; the size of the adopted model is very small, the calculation amount is low, and the requirement for calculation resources is low; and the system is low in cost and has large-scale application potential.

Description

technical field [0001] The invention relates to the technical field of driving, in particular to a fast parking space detection method based on deep learning. Background technique [0002] Parking space detection and positioning are the basis of automatic parking systems and assisted parking systems. In existing methods, methods based on non-deep learning rely on manual extraction of parking space sideline features for parking space detection, which has poor adaptability to the environment. For example, in There are problems with the detection system failing when the markings on the sidelines of the parking spaces are not clear, the shadows of buildings, reflections caused by stagnant water, and blurred cameras. The method based on deep learning usually has a large model size, a large amount of calculation, and high requirements for computing equipment. The high system cost is not conducive to large-scale application and promotion on vehicles. Methods with robust detection ...
