Problems solved by technology

[0002] Usually the existing target tracking algorithm is an offline learning feature extractor, and the target area is sent to the feature extractor to obtain a better feature representation. Using the trained feature extractor, the features extracted in the target area are directly in the test frame image Perform related operations in the features of this method. This method is simple, fast, and works well in simple scenes, but it has poor robustness and cannot handle complex scenes (similar object problem)

Abstract

The invention provides a target tracking method and device, equipment and a readable storage medium. The method comprises the steps: acquiring a video containing a to-be-tracked target; framing an image of the target in a first frame of image of the video to obtain a first target image, taking the first target image as a training sample, and performing online training on a neural network model to obtain an initialized classifier model; performing online optimization on the initialized classifier model based on the image after the first frame of image to obtain an optimized classifier model and an image which stops optimization; and searching the target in the image after the optimized image by using the optimized classifier model to realize the tracking of the target. According to the method, the appearance characteristics of the target area are utilized, and the content of the target background area is also utilized, so that the discrimination capability is relatively high, the robustness is relatively good, and the target in a complex scene can be tracked.
