Abstract

The invention provides a traffic sign detection method for unmanned drive. The method comprises the steps of performing multi-scaling on an image, generating integral images, selecting feature images,and sliding to traverse the images, wherein the multi-scaling is performed on the input image to be detected, and thus multiple scaled images are generated; the feature images, comprising color information and gradient information, of the scaled images are computed, and the integral images of the feature images are computed; features of the integral images are selected via a feature selection classifier, and thus selected feature images are generated; and the selected feature images are traversed via a sliding window, and traffic signs in the sliding window are detected. The invention relatesto electronic equipment and a readable storage medium, used for executing the traffic sign detection method for unmanned drive; the invention also relates to a traffic sign detection system for unmanned drive; according to the method, equipment, medium and system provided by the invention, the image processing efficiency is improved, the traffic sign detection is high real-time and the detectionaccuracy is high.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic sign detection method, device, medium and system for driverless driving. Background technique [0002] The vehicle driverless system has a wide range of economic benefits and far-reaching social influence. Unmanned vehicles need to detect roads, vehicles, traffic signs, and pedestrians in the scene accurately and robustly in real time. The real-time requirements for traffic sign detection supporting unmanned vehicles are high. When performing traffic sign detection, the input image is a video taken during vehicle motion. The existing traffic sign detection for unmanned vehicles has the following problems: The captured video contains a large amount of environmental information, and it is impossible to perform stable and effective detection of traffic signs in an environment with mixed backgrounds; traffic signs are generally small, with a variety of types, and l...
