Problems solved by technology

[0004] However, in the existing technology, the method of panorama acquisition and update requires professional acquisition equipment, and the cost is relatively high
The accuracy of satellite image collection is poor, and the user feedback method is easy to introduce error information, so the above two methods cannot obtain accurate traffic light information

Abstract

The present application discloses a method, device, electronic device and storage medium for identifying road traffic lights, and relates to the technical field of big data. The specific implementation scheme is as follows: acquiring the user's trajectory information; screening the user's trajectory information to obtain candidate trajectory information with parking behavior; acquiring the location where the parking behavior occurs and the corresponding road feature data in the candidate trajectory information ; if the road feature data satisfies the preset condition, determine that the location where the parking behavior occurs is a real traffic light intersection. Therefore, the location information of the road traffic lights can be accurately and efficiently obtained through the user's trajectory information, and the entire identification process has low requirements on the collection equipment and strong timeliness.

Description

technical field [0001] The present application relates to big data technology in the field of data processing technology, and in particular to a method, device, electronic equipment and storage medium for identifying road traffic lights. Background technique [0002] The identification and early warning of traffic lights can facilitate vehicle navigation. [0003] In the prior art, the traffic lights on the road are generally determined by means of panorama acquisition and update, satellite images, user feedback and the like. Among them, the method of panoramic acquisition and update requires the installation of acquisition equipment on the vehicle. The acquisition equipment collects real road images and images of scenes around the road, and then analyzes the images to obtain traffic light information. The method of satellite imagery refers to obtaining images collected by satellites and analyzing the images to obtain traffic light information. The way of user feedback ref...
