Research of tracking the oriented six-dimensional pose of the 360° ring screen

Focus on the research of the tracking of the oriented six-dimensional pose of the 360° ring screen, an optical tracking method based on linear random distribution of mark point is proposed. The generatrix of the cylinder is straight. Utilizing the constant cross ratio of projective transforming, different linear spots mark can be distinguished by the geometrical hash algorithm. A coding method based on the order of permutation is proposed to erase the misrecognized points. The tracking of the oriented six-dimensional pose of the camera is realized. The precision of the tracking is characterized. By simulating the 360° ring screen tracking system, the mean value of the reprojection error is used to analyze the tracking performance and precision under different distances and angles, and the real time property and robustness of the system are tested.
