Dynamic target behavior prediction method and system

Abstract

The invention relates to a dynamic target behavior prediction method and system, belongs to the technical field of prediction, and solves the problems that a prediction method in the prior art is poor in real-time performance and is only used for behavior prediction of a single target and task planning and distribution of the single target. The dynamic target behavior prediction method comprises the following steps: detecting a dynamic target in real time; realizing multi-target tracking through a target tracking method; determining the coordinate of each frame of target detection result in a map coordinate system in combination with the pose information of the binocular camera, and connecting the same target points of different frames to obtain a target track; and predicting the specific behavior of the dynamic target through the tangential direction of the target track. The specific behavior of the dynamic target can be predicted through the tangential direction of the target trajectory, so that traffic accidents can be avoided, and tasks such as multi-target search and hunting can be better completed.

Description

technical field [0001] The present invention relates to the technical field of prediction, in particular to a dynamic target behavior prediction method and system. Background technique [0002] In computer vision, object detection is to scan and search for objects in images and videos (ie, a series of images), and in general it is to locate and identify objects in a scene. [0003] Tracking is a sequence of detections. Assuming that in a traffic video, you want to detect a car or a person, use snapshots at different moments of the video to detect objects, for example, a car or a person. The target is then tracked by examining how the target moves in different frames of the video. For example, if you want to calculate the speed of the target, you can calculate the moving distance of the target through the change of the target coordinates in the two frames of images, and divide it by the interval time between the two frames of images. [0004] Behavior prediction is to pred...
