Abstract
The traditional optical tracking system is easily affected by occlusion and a narrow field of vision, which leads to the failure of surgical instrument tracking. To solve this problem, a multi-target tracking method based on multi-camera module information fusion is proposed. Firstly, a multi-target tracking block is installed at the end of the surgical instrument. A method of solving the end position of surgical instruments based on multi-object tracking is proposed to improve the success rate of surgical instrument tracking. Secondly, motion blur is easy to occur in surgical instrument tracking. A method to reduce the tracking failure caused by motion blur is proposed to improve the sharp edge of the image. Then, a method of information fusion of multi-camera module is proposed to track surgical instruments. Finally, experiments are designed to verify the stability and accuracy of the proposed method. The tracking accuracy is 1.89 ± 0.24 mm.
