Abstract

The embodiment of the invention provides a road traffic sign recognition method and apparatus. The road traffic sign recognition method includes the steps: acquiring the shot images; utilizing line segments with inclined characteristics to search triangular signs or circular signs from the shot images; and according to the found triangular signs or circular signs, recognizing the road traffic signs of the warning type or the forbidden type. The road traffic sign recognition method and apparatus can avoid the process of searching the signs or images with horizontal or vertical characteristic from the shot images, thus improving the searching speed, reducing the area range for recognition, reducing the recognition objects, improving the recognition speed, and accelerating recognition of the road traffic signs as a whole, and can more timely prompt users according to the recognized road traffic signs, thus enabling vehicle driving to be more safe.

Description

technical field [0001] The present invention relates to the technical field of vehicle assisted driving, in particular, the present invention relates to a road traffic sign recognition method and device. Background technique [0002] With the development of society and economy and the improvement of people's living standards, vehicles have been widely popularized. In order to improve driving safety, various methods of vehicle auxiliary driving have begun to appear, for example, a method of recognizing road traffic signs from captured images and reminding the driver in time.
