Abstract

The invention discloses a Kalman filtering and TLD (tracking-learning-detection) algorithm integrated target tracking method. The method comprises steps as follows: firstly, the principle of a Kalman filter is analyzed, and the Kalman filter is improved; then a TLD algorithm is enhanced by the aid of the improved Kalman filter, and the reliability of a system is improved; finally, a detection module is improved by the aid of a prediction result obtained through the improved Kalman filter, the detection area of the TLD algorithm is reduced, and the tracking instantaneity is further improved.

Description

technical field [0001] The invention relates to a target tracking method combining Kalman filter and TLD algorithm, which belongs to the technical field of image processing. Background technique [0002] The detection and tracking of moving targets has always been a hot issue in the field of computer vision research, and it can be widely used in various fields of national defense and civilian use, such as intelligent monitoring, aerospace, artificial intelligence, navigation and guidance, etc. In the process of target detection and tracking, many challenges will be faced, such as target occlusion, light changes, target trajectory changes, target moving too fast, appearance of similar targets, complex background, etc. [0003] With the continuous improvement of computer performance, the ability to process large-scale data such as video images has also been continuously improved, so that target detection and tracking technology has been greatly developed. In 1950, Gibson firs...
