Abstract

The invention relates to the technical field of vehicle navigation, and discloses a road condition detection method and device, electronic equipment and a readable storage medium, and the road condition detection method comprises the steps: receiving a road condition video from video collection equipment; extracting a plurality of video frame images from the road condition video, and obtaining a plurality of optical flow density images based on the plurality of video frame images, wherein the optical flow density image is used for representing dynamic information formed by movement of each pixel point in a video frame image relative to an object; and respectively classifying the plurality of video frame images and the plurality of optical flow density images, and determining a road condition result based on the classification of the video frame images and the optical flow density images. The road condition detection method provided by the invention not only depends on the traffic flowspeed, but also can obtain a more accurate road condition result.

Description

technical field [0001] The present application relates to the technical field of vehicle navigation, in particular, the present application relates to a road condition detection method, device, electronic equipment and readable storage medium. Background technique [0002] In map services, it is usually necessary to determine road condition information, such as whether the road is congested, in order to plan a reasonable navigation route for users, and also help cities build traffic warnings and dispatch urban traffic systems. [0003] At present, when analyzing road condition information, it is usually to collect GPS (Global Positioning System, Global Positioning System) positioning point information of vehicles on the road, calculate the real-time speed of the vehicle on each road section, and combine the speeds of multiple vehicles on the same road section to determine road congestion. This method is more dependent on the speed of the traffic flow, and the road condition...
