Embodiment Construction

[0055]In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0056]The traffic identification detection method provided by this application can be applied tofigure 1 The application environment is shown. Wherein, the terminal 102 communicates with the server 104 over the network. The terminal 102 acquires the road image to be detected and transmitted to the server 104. The server 104 is based on the location information of the road image to be detected from the historical road image collection, and the historical road image in the historical road image collection also includes the target traffic identity. The server 104 treats the road image and the refer...

Abstract

The invention relates to a traffic sign detection method and apparatus, a computer device and a storage medium. The method comprises the steps of obtaining a to-be-detected road image containing a target traffic sign; obtaining a matched reference road image containing the target traffic sign from the historical road image set based on the position information of the to-be-detected road image; performing feature extraction on the to-be-detected road image and the reference road image to obtain a target feature set corresponding to the to-be-detected road image and a reference feature set corresponding to the reference road image; calculating the matching degree of the target feature set and the reference feature set, and determining the consistency detection result of the target traffic sign in the to-be-detected road image and the reference road image based on the matching degree; and determining a target detection state of the target traffic sign in the to-be-detected road image based on the consistency detection result. By adopting the method, the traffic sign detection accuracy and efficiency can be improved, and the to-be-detected road image with the changed target detection state of the target traffic sign can be used for updating a map.

Description

Technical field[0001]The present application relates to the field of computer technology, and more particularly to a traffic identification detection method, a device, a computer device, and a storage medium.Background technique[0002]Traffic logo is an important traffic element that indicates the direction of travel of the vehicle and is an important part of road data. The map is used to realize the world, and the update of road data is the basis of its premise. The update of road data can be updated by the matching of the road image.[0003]In the conventional technique, the matching of the road image is mainly to extract the feature points in the image, and then use the geometric constraint to parse the feature points on the map, and when the matching point number exceeds a specific threshold, it is considered to match each other. However, the conventional method is simply considered to consider the overall similarity of the image pair, and it is easy to detect the case where the tr...
