【摘要】：POS系統(tǒng)是移動測量系統(tǒng)的重要組成部分,其位置姿態(tài)精度一直受到廣泛關(guān)注。結(jié)合全站儀、激光跟蹤儀、GNSS授時裝置等傳感器,設計了動態(tài)精度檢測系統(tǒng),開展了POS系統(tǒng)動態(tài)精度檢測方法研究。主要采用單次測量時間統(tǒng)計、平滑曲線擬合等方法探測檢測系統(tǒng)的測量誤差,并在誤差剔除的基礎上,結(jié)合ICP算法,利用跟蹤儀高精度測量數(shù)據(jù),對全站儀數(shù)據(jù)進行修正,提高檢測系統(tǒng)整體測量精度。最后,在某實驗區(qū),進行車載POS系統(tǒng)動態(tài)跟蹤實驗,分別采用整體軌跡對比和實時點位對比方法進行POS系統(tǒng)事后處理精度檢測和實時導航精度檢測。實驗結(jié)果表明:采用該種檢測方法,動態(tài)檢測系統(tǒng)能檢測出POS實時和事后處理的動態(tài)定位精度。
[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.
