Scale adaptive target tracking method applied to mine laneway mobile inspection image

Abstract

The invention relates to a scale adaptive target tracking method applied to a mine laneway mobile inspection image, belongs to the technical field of target tracking, and solves the problem that an existing mine target tracking algorithm cannot obtain a better tracking effect in scenes such as violent target change, shielding and background interference. The scale adaptive target tracking method comprises the following steps: receiving a current video frame of a mine laneway mobile inspection video frame sequence, and obtaining a to-be-detected image block in the current video frame accordingto a target tracking position and scale information of a previous frame; extracting HOG features and LQC features of a to-be-detected image block in the current video frame, and obtaining an HOG feature response graph and an LQC feature response graph through calculation by means of an HOG feature correlation filter and an LQC feature correlation filter respectively; performing weighted fusion response on the HOG feature response graph and the LQC feature response graph, and determining a maximum value position in a weighted fusion response result as a target position of the current video frame; and performing scale estimation on the target position by using a scale filter to obtain scale information of the current video frame.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a scale-adaptive target tracking method applied to moving inspection images of mine roadways. Background technique [0002] The coal mining industry occupies an important strategic position in my country, is an important industry of the national economy, and is also the source of most energy demand. In order to ensure the healthy development of the coal industry, the security of normal work in mines and the safety of personnel have become the most important issues of social concern. In recent years, the emergence of the mine Internet of Things and the concept of intelligent mines has brought intelligent coal mining technology to a new level, which can carry out digital video monitoring of the coal mining process, thereby ensuring the safety of mine work. Mine roadway mobile inspection is an important means to improve the safety management level of coal mines. Through int...
