Abstract

Embodiments of the present application disclose a traffic sign recognition method and apparatus. One embodiment of the method includes generating a binary image corresponding to a road condition image, and determining a traffic sign associated image associated with a traffic sign on a road in the binary image; projecting the traffic sign related image on a histogram in a preset direction to obtaina projection histogram, and determining a target boundary line based on the projection histogram; Based on a target boundary line, a target area in the road condition image is determined, and an image in the target area is recognized to recognize a traffic sign in the target area. Accurately determine the target area where the road sign is located, image recognition of the image in the target area, recognize the road traffic signs, improve the speed of road traffic signs recognition and reduce the cost of identifying traffic signs.

Description

technical field [0001] The present application relates to the field of computers, in particular to the field of navigation, and in particular to a traffic sign recognition method and device. Background technique [0002] In the navigation process such as AR navigation, the recognition of traffic signs on the road is one of the key links. At present, the entire road condition image is usually divided into multiple regions, and image recognition is performed on each region one by one to recognize traffic signs on the road, resulting in huge overhead. Contents of the invention [0003] Embodiments of the present application provide a traffic sign recognition method and device. [0004] In the first aspect, an embodiment of the present application provides a traffic sign recognition method, the method including: generating a binary image corresponding to a road condition image, and determining a traffic sign-associated image associated with a traffic sign on a road in the bin...
