Pen tip tracking method, medium and computing equipment

Abstract

The invention discloses a pen point tracking method, a medium and computing equipment. The method comprises the following steps: acquiring a pen wielding video; using a specific detection model to obtain a template image from the pen wielding video, wherein the template image comprises a to-be-tracked pen point, and the specific detection model is obtained through training based on a training sample set comprising a plurality of different pen point images; and determining the pen point position in the pen wielding video based on the template image, the pen wielding video and a tracking model constructed based on a twin network. According to the pen point tracking method, pen point images in pen wielding videos in different environments can be accurately identified; moreover, the capability of resisting the influence of shooting conditions such as light and shadow of the tracking task is effectively improved, and meanwhile, the robustness, the real-time performance and the accuracy of the tracking task are ensured.

Description

technical field [0001] The invention relates to the field of image tracking, in particular to a pen tip tracking method, medium and computing equipment. Background technique [0002] In the current pen tip tracking tasks, most of them regard the pen tip as a small target, and then rely on the method of template matching to achieve tracking. However, there are also obvious differences between the nib and ordinary small targets. The nib target is easily affected by factors such as light and shadow during the writing process, resulting in a decrease in tracking accuracy, and even missing the target when the writing speed is too fast. Contents of the invention [0003] The main purpose of the present invention is to provide a pen tip tracking method, medium and computing device, aiming to solve the problems mentioned in the background art. [0004] In order to achieve the above object, the present invention proposes a nib tracking method, comprising: [0005] Obtain the pen ...
