Traffic sign recognition method and device, computer equipment and storage medium

Abstract

The invention relates to a traffic sign recognition method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-recognized picture; determining position information and fuzzy category information of target information in the to-be-identified picture based on a detector model determined through training; determining a foreground picture of the to-be-identified picture according to the position information, wherein the foreground picture comprises target information; determining a corresponding classifier model obtained through training according to the fuzzy category information; and identifying the foreground picture through a classifier model, and determining the specific category information of the traffic sign of the target informationin the to-be-identified picture. Through the above method, according to the traffic sign recognition method, the traffic sign can be recognized only by inputting the to-be-recognized picture into themodel obtained through training, and finally the specific category of the traffic sign contained in the to-be-recognized picture is output, so that the recognition time of the traffic sign can be shortened, the recognition efficiency can be improved, and corresponding prompts can be conveniently made according to the recognized specific category.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a traffic sign recognition method, device, computer equipment and storage medium. Background technique [0002] With the development of traffic, there are more and more vehicles, and the traffic accidents that follow are more and more common. The road conditions in our country are complex and there are many traffic signs. There may be great differences in the regulations on the road in various places, so the traffic signs set are also very different, so the identification of traffic signs appears. [0003] Traffic sign recognition is one of the important modules of the current intelligent assisted driving system. The current mainstream target detection algorithm is mainly based on the deep learning model. This method needs to train the network through a large number of data sets. There are some such methods in the existing technology. However, the traffic sig...

Problems solved by technology

[0003] Traffic sign recognition is one of the important modules of the current intelligent assisted driving system. The current mainstream target detection algorithm is mainly based on the deep learning model. This method needs to train the network through a large number of data sets. There are some such methods in the existing technology. However, the traffic sign recognition methods in the prior art all have problems such as insufficient sample balance and insufficient efficiency.
