Method and device for identifying stopped vehicle

Abstract

According to the invention, the unmanned aerial vehicle cruises to shoot the road surface video and transmits the road surface video to the computing device; the computing device receives the road surface video, then obtains a plurality of video frames corresponding to the road surface video, detects and tracks vehicles in the plurality of video frames, then calculates a transformation matrix between adjacent video frames, further calculates the detected displacement of each vehicle in the actual scene, and finally judges whether the vehicle stops running in the actual scene or not by counting the accumulated displacement of each vehicle in a period of time. Compared with an existing traditional method, the invention does not need to delploy monitoring equipment on site in advance, the application is flexible, deployment cost and management cost are low, and the parking behavior on the road surface can be monitored in a large range; the unmanned aerial vehicle can always move and fly without hovering in the air to fix a monitoring picture, so that more convenient, efficient and flexible road surface parking identification can be realized.

Description

technical field [0001] The present application relates to the communication field, and in particular to a technology for identifying a stopped vehicle. Background technique [0002] With the rapid development of science and technology, drone technology has gradually entered people's field of vision. With its unique advantages, drones are quickly applied to various industries. With the gradual popularization of highway digitalization and intelligence, drones have also shown more and more application prospects in the highway field. UAVs fly high and see far, especially when facing holidays, accidents, weather and other factors that cause road congestion on the expressway, the high-definition camera on the UAV can transmit the picture to the monitoring platform in real time at the first time , to facilitate the high-speed traffic police to deploy police forces according to the aerial photography of road conditions. Illegal parking on the expressway is the most common traffic...

AI Technical Summary

Problems solved by technology

At present, the supervision of highway vehicle driving still requires a lot of manpower and material resources, especially in the monitoring of illegal parking. Illegal parking is mainly found through human road inspection and fixed camera monitoring. Human road inspection requires a lot of manpower and fixed cameras. Surveillance can only rely on the cameras that have been set up, the monitoring range is small, and the flexibility is poor
