Visual target tracking method and system oriented to image sequence

Abstract

The invention discloses a visual target tracking method and a visual target tracking system oriented to an image sequence. The visual target tracking method comprises the following steps of training aconvolutional regression model for target tracking by use of a given initialized image and a to-be-tracked target rectangular frame; predicating the position of a target by use of the convolutional regression model obtained by training; further predicting the size of the target on the basis of a prediction result of the target position; and updating the convolutional regression model according tothe position and the size of the target obtained by tracking. According to the visual target tracking method and the visual target tracking system oriented to the image sequence, technologies such astraining of a target overall regression model, training of a target texture regression model, prediction of the target position, prediction of the target size, updating of a tracking model and the like are involved, the interference of various environmental factors in a tracking scene can be fully overcome to implement accurate prediction for the target position and size, and relatively higher commercial values and research significances are possessed.

Description

Technical field [0001] The present invention relates to the technical field of computer vision, in particular to a method and system for tracking an image sequence-oriented vision target. Background technique [0002] In the field of computer vision, it is usually necessary to use intelligent algorithms to automatically identify and analyze video information to achieve intelligent control of the equipment. The target tracking algorithm based on the visual image sequence can make full use of the existing single image-oriented target detection algorithm to quickly and reliably track the trajectory of the target in the video, which improves the technical support for understanding and analyzing the video. [0003] With the rapid expansion of industrial production scale, the degree of automation and intelligence in the production process of industrial products also needs to be continuously improved. For example, in a video surveillance system, intelligent algorithms are required to aut...
