摘要

A tracking algorithm based on arbitrary geometric shape and Unscented Particle Filter is proposed in this paper. Traditional tracking algorithm based on arbitrary geometric shape has following advantages, matching convenient, high precision, but when the geometric shape is not fully visible it results tracking failure so that restricts its use. Another tracking algorithm based on natural feature utilizes natural feature points to finish registration, there are disadvantages such as error accumulation as time goes by. This approach firstly uses arbitrary geometric shape to finish camera calibration, then use unscented particle filter to predict the possible location of the camera, and get 3-D registration matrix, it can reduce non-linear, non-Gaussian interfere brought by other issues. Experiment results show that this method can efficiently work under the circumstances of occlusion, large changes in illumination, and have a high accuracy.
