POS(Position and Orientation System)is one of the most important part of mobile mapping system,whose position and orientation accuracy has arisen lots of *** researches have been carried on improving the accuracy of POS,but less have been carried on testing the accuracy of POS,whose tests depend greatly on manufacturer and lack public and systematic *** to this situation,This paper analyses the calibration techniques for testing the dynamic position accuracy of POS(Position and Orientation System).The methods of counting the time of single measurement and curve fitting have been used for eliminating gross error from the raw observation *** algorithm of icp(Iterative Closest Point)is used for modifying the trajectory of total-station system,which is realized by the comparison between high-accuracy trajectory of laser tracking system and that of total-station system,to enhance the accuracy of dynamic *** trajectory comparison and real-time comparison are used for testing the dynamic position accuracy of *** experiments have been carried out to verify the feasibility that this calibration method can be used for testing the dynamic position accuracy of POS.
This paper introduces methods for monitoring rock slope movements in Alpine environments based on terrestrial images. The first method is a photogrammtric point cloud-based deformation analysis, relying on M3C2. Altho...
