Abstract

The invention discloses a target tracking method based on a YOLOv3 algorithm and a DSST algorithm. The method comprises the following steps: training a target detection model, inputting an image, evaluating a position, detecting a target, taking a position model, a scale model, a target position and a target scale as inputs in the step 3) when a next frame of image comes, and repeating the steps 3) to 4) to complete a video target tracking function. The method is beneficial to fully verifying and objectively evaluating the composition factor influence of the overall effect of the method in twostages of the implementation process, and is also convenient to clarify the improvement and reinforcement targets of the target tracking method. The operation amount of a detection algorithm is effectively reduced, so that the operation speed is increased and the hardware requirement is reduced. The anti-interference performance of the tracking algorithm can be improved, and the success rate andreal-time performance of the tracking algorithm are further improved.

Description

technical field [0001] The present invention relates to the field of video target tracking, in particular to a target tracking method using a deep learning YOLOv3 algorithm (deep learning regression detection algorithm) combined with a DSST algorithm (differential scale space tracking algorithm). Background technique [0002] The tracking of moving targets in video has always been one of the most important research directions in the field of computer vision, and it is widely used in security, transportation, military and other research fields. Existing video target tracking methods are roughly divided into two categories: generative models and discriminative models: generative model methods mainly use the learned target model to search image regions and minimize reconstruction errors, typical representatives are Mean-Shift, Kalman filter and Particle filter, etc.; the main idea of ​​the discriminant model method is to regard the tracking problem as a binary classification pr...
