Method and device for outputting information

Abstract

The invention provides a method and device for outputting information, which relate to the field of image recognition, in particular to the field of intelligent transportation, and can be applied to an automatic driving scene. The method in the specific implementation scheme comprises steps of acquiring a real-time video stream, detecting key points of a running target vehicle and a parking space vehicle parked in the parking space from the real-time video stream, performing target tracking according to the key points of the target vehicle to obtain a tracking trajectory, if the tracking trajectory intersects with the area where the parking space vehicle is located, conducting coordinate conversion according to the key points of the target vehicle and the key points of the parking space vehicle, and acquiring a first area and a second area of a top view under physical coordinates, and if the first area and the second area are overlapped, outputting prompt information. According to the embodiment, the adaptability of the parking system can be improved, the functions of the on-road parking system are increased, meanwhile, traffic accidents are reduced, the traffic environment and the social environment are optimized, and development of the intelligent traffic field is actively promoted.

Description

technical field [0001] The present disclosure relates to the field of image recognition, especially to the field of intelligent transportation, and can be applied to automatic driving scenarios. Background technique [0002] With the development of my country's economy, the number of vehicles in the market will continue to increase, and problems such as parking difficulties and effective management of parking spaces will become more and more serious. In this era, many smart parking systems have been derived, among which video-based capture devices have attracted widespread attention. The way of video can solve the parking problem very well, but this system does not have the early warning function of vehicle scratching and vehicle item theft. If there is no video at the scene, the parking company cannot provide relevant evidence when a traffic accident occurs, which will easily cause traffic disputes; if there is video, the system will record 24 hours a day, and changes in v...

AI Technical Summary

Problems solved by technology

If there is no video at the scene, the parking company cannot provide relevant evidence when a traffic accident occurs, which will easily cause traffic disputes; if there is video, the system will record 24 hours a day, and changes in video storage equipment and front-end networking will cause parking system costs Increase rapidly
