| Abstract: | Flexible coordinate measuring based on laser tracking measurement system (LTS) is good to detect 3D coordinate of moving target, however the system suffers from various interferences resulting in lower accuracy. The application of Kalman filtering algorithm is extend in the LTS to solve the problem. The laser tracking system is introduced. The state model of the laser tracking measurement system is developed, and the linearization method of the model is analyzed. A Kalman filtering algorithm is adopted to the system. The result of the simulation shows that Kalman filter works well for the improvement of the accuracy of LTS. |
