A development and calibration techniques of high accuracy 3D Mobile Mapping Systems (MMS) of Hydro Informatics Institute (HII).

Abstract

This article presents a development of 3D mapping from surveying technology called “Mobile Mapping System (MMS)” and its calibration. The calibration techniques use total station camera, terrestrial laser scanners and a computer measuring machine (CMM) to get high accuracy of Lever Arm and Bore Sight with comparing to the system center. Then, ground control points (GCPs) on the testing area are created by a total station camera. After testing the MMS, the data will be corrected and processed by using Qinertial program together with the calibrated Lever Arm and Bore Sight data. The processing results can give two type of data which are 360 degree of the surveying object photos, and point cloud data. At 15 meters apart, the MMS surveying technique could give an accuracy results on the horizontal position of +/- 5 cm and on the vertical position of +/- 7 cm by comparing with GCP.
