[Abstract]:The POS system is an important part of the mobile measurement system, and its position and attitude accuracy has been paid more and more attention. A dynamic precision measuring system is designed based on the sensors such as total station and laser tracker. In this paper, the dynamic precision detection method of POS system is studied. The measurement error is detected by single measurement time statistics, smoothing curve fitting and so on. On the basis of error elimination, combined with ICP algorithm, the dynamic precision detection method of POS system is studied. Using the high precision measurement data of tracker, the data of total station is corrected to improve the overall measuring accuracy of the detection system. Finally, in a certain experimental area, the dynamic tracking experiment of POS system on vehicle is carried out. The whole trajectory contrast and the real time point position contrast are used to detect the post-processing accuracy and the real-time navigation accuracy of POS system, respectively. The experimental results show that the proposed method can be used to detect the accuracy of post-processing and real-time navigation of the POS system. The dynamic detection system can detect the real-time and post-processing dynamic positioning accuracy of POS.
