Abstract

The invention discloses an infrared target tracking method and device based on response graph fusion in the technical field of infrared image processing, which includes acquiring the target image corresponding to the tracking target in the infrared image of the initial frame and the position point corresponding to the target image, respectively acquiring the The normalized grayscale feature and directional gradient histogram feature of the target in the initial frame; according to the target position in the initial frame image, use the correlation filtering algorithm to train the correlation filters of the two features; compared to using a single feature and different features in series The method of feature representation in this way can improve the tracking accuracy and tracking success rate to a certain extent. At the same time, this method can maintain better tracking robustness for infrared image sequences in complex situations, and realize the motion detection in infrared images. Persistent Robust Tracking of Objects.

Description

technical field [0001] The invention relates to the technical field of infrared image processing, in particular to an infrared target tracking method and device based on response map fusion. Background technique [0002] Infrared target tracking technology has been widely studied in the fields of intelligent monitoring and automatic driving systems in recent years. Compared with visible light images, there are less research work and achievements on infrared image target tracking. Compared with visible light images, thermal infrared images have some negative properties, such as low signal-to-noise ratio, small resolution, less texture information, and blurred edges. These negative properties increase the difficulty of extracting highly discriminative features from infrared images. At present, there are many related target tracking algorithms for visible light images, but due to the large difference between them and infrared image tracking methods in feature representation, ...
