Abstract

The invention provides a prediction method and device of movement track. The method comprises the steps that the n+1 frame before the frame to be predicted and the corresponding target coordinate areselected as the reference frame and the reference coordinate; a generalized inverse matrix can be established based on the n frame before the frame to be predicted and the reference frame; a coordinate matrix can be established based on the n frame before the frame to be predicted in the video and the said reference frame; a secondary matrix can be established based on the frame to be predicted inthe video and the reference frame; a target track prediction model can be established based on the generalized inverse matrix, the coordinate matrix, and the frame matrix; a coordinate of a mobile object in the frame image to be predicted can be predicted based on the target track prediction module. The invention is advantageous in that a more accurate track prediction can be provided, and a lotof calculation can be prevented.

Description

technical field [0001] The present invention relates to the technical field of video images, in particular to a method and device for predicting motion trajectories. Background technique [0002] Target tracking and target trajectory prediction technology has important applications in the defense industry, aerospace and security fields. Compared with radio tracking measurement, video target tracking measurement has the advantages of high precision, good concealment and strong intuitiveness. The moving target in the video image not only has spatial characteristics, but also has the trajectory characteristics formed by the target relative to the time axis. Target tracking and trajectory prediction based on video images can make full use of the spatial distribution characteristics and trajectory characteristics of the target, thereby improving tracking performance. and predictive quality. [0003] The purpose of prediction in video image processing is to speed up detection in...
