Guide board recognizing method and device

Abstract

The invention discloses a guide board recognizing method and device and belongs to the technical field of computers. The guide board recognizing method comprises the steps that color detection is conducted on each pixel point in a street scene image to be processed, so that the pixel points corresponding to the color of a guide board are obtained; the pixel points corresponding to the color of the guide board are connected, so that at least one first connection area is obtained; area filtration is conducted on the at least one first connection area according to the image characteristics of the guide board, so that at least one second connection area is obtained; the image characteristic of each second connection area is extracted; the image characteristics of the second connection areas are filtered by means of a guide board reorganization support vector machine, and a guide board area is screened out from the at least one second connection area, wherein the guide board reorganization support vector machine is obtained through guide board image training; character recognition is conducted on the guide board area, so that guide board information of the guide board area is obtained. According to the guide board recognizing method and device, due to the fact that manual intervention is not needed in the guide board reorganization process, guide board reorganization is reduced, and guide board reorganization efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a road sign recognition method and device. Background technique [0002] In order to facilitate users to grasp the surrounding situation of POI (Point of Interest, information point), more and more street view maps have appeared. Wherein, the street view image of the street view map may include many street signs, which are used to indicate which road or street the street view belongs to. By recognizing the street signs in the street view image, the information included in the street view map can be supplemented, marked, calibrated, etc., so that the user can easily grasp the geographic location of the street view. [0003] Recognizing street signs in street view images in related technologies usually needs to be implemented manually, that is, manually identifying street signs in street view images and extracting street sign information included in the street signs. [0004] I...

AI Technical Summary

Problems solved by technology

[0005] Due to the large scale of street view image data, it takes a lot of manpower to manually identify street signs, and the cost is high

In addition, manual recognition of street signs is often time-consuming, which makes street sign recognition inefficient
