Comparison of ultralight laser scanners

On 18-21 October 2016 the Joint 3D Geoinfo Conference was held. During this conference results of a comparison of ultralight laser scanners were presented. These scanners are mounted on unmanned aerial vehicles (UAV). Within the analysis the influence of the accuracy of the sensor components on the final measurement accuracy was examined. The results indicated a significant impact of the inertial measurement unit (IMU). Because of the weight limitations, the IMU units which are a part of light laser scanners are lighter that the IMU units mounted on airborne laser scanners. Additionally, the analysis showed that the proper selection of the ultralight laser scanners can cause the accuracy increase. The results are presented in the publication available at: http://www.int-arch-photogramm-remote-sens-spatial-inf-sci.net/XLII-2-W2/87/2016/isprs-archives-XLII-2-W2-87-2016.pdf
