The systematic calibration of the LiDAR system is only one of the steps required to derive high-quality LiDAR data. Additional quality control and assurance measures are also needed. The vertical accuracy of LiDAR measurements is relatively easy to verify using two different methods. One method compares the LiDAR elevations with measurements of higher accuracy, such as those from GPS surveys, for the same ground features such as 38 Advances in mapping from remote sensor imagery roads. 15 m for smooth ground surfaces.
9. 9 Perspective transformation between image and object space straight lines and the coplanarity constraint for intermediate points along the lines. the image line is contained within the plane defined by the perspective center of that image and the two points defining endpoints of the object line. 9) where V1 = the vector connecting the perspective center to the first endpoint along the object line V2 = the vector connecting the perspective center to the second endpoint along the object line V3 = the vector connecting the perspective center to an intermediate point along the corresponding image line The coplanarity constraint can be introduced for all of the intermediate points along the image space linear feature.
