Problems solved by technology

In real life, some vehicles have behaviors that do not comply with the driving regulations, such as the behavior of not turning on the turn signal when the vehicle changes lanes, which seriously affects or endangers the normal traffic order
[0003] In related technologies, methods such as on-site law enforcement or remote manual detection have the problems of low recognition efficiency and small coverage area, and there is an urgent need for automatic analysis and recognition of vehicle behavior based on computer vision

Embodiment Construction

[0063]The technical solutions of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described implementations are part of the implementations of the present disclosure, but not all of them. Based on the implementation manners in the present disclosure, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure. In addition, the technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not constitute a conflict with each other.

[0064] Under the current traffic regulations, it is illegal for a vehicle to change lanes without turning on the turn signal while participating in traffic. At present, in most scenarios, it is necessary to use on-site law enforcement or remote manual monitoring to identify ...

Abstract

The invention relates to the technical field of computer vision, in particular to a vehicle behavior detection method, device and system. The vehicle behavior detection method comprises the following steps: acquiring a video stream sequence of a lane changing stage of a target vehicle, wherein the video stream sequence comprises multiple frames of images; obtaining space information of a steering lamp of the target vehicle in the multiple frames of images through detection according to the video stream sequence; detecting time sequence information of the steering lamp among the multiple frames of images based on the space information; and predicting the state of the steering lamp of the target vehicle according to the time sequence information. According to the detection method provided by the embodiment of the invention, detection and identification of vehicle behaviors are realized based on computer vision, the detection efficiency is improved, and the robustness and the detection precision of a detection system are improved.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, in particular to a vehicle behavior detection method, device and system. Background technique [0002] At present, vehicles are still an important participant in the field of transportation, and the driving behavior of vehicles is also a research hotspot in the field of transportation. In real life, some vehicles have behaviors that do not conform to the driving regulations, such as the behavior of not turning on the turn signal when the vehicle changes lanes, which seriously affects or endangers the normal traffic order. [0003] In related technologies, methods such as on-site law enforcement or remote manual detection have the problems of low recognition efficiency and small coverage area, and there is an urgent need for automatic analysis and recognition of vehicle behavior based on computer vision. Contents of the invention [0004] In order to realize vehicle behavior an...
