The technique is based on expressing the system calibration parameters within the direct-georeferencing equation separately for each target point, and conditioning a group of points to lie on a common surface of a known form such as plane.LIDARCalibrationGeoreferencingGPS/INSLaser scanningAccuracyiQualtopomapptext::journal::journal article::research article
