Abstract
It is expected that point cloud data generated by UAV photogrammetry will be utilized in various management scenes such as construction management and disaster. On the other hand, in UAV photogrammetry, there are problems that require enormous time to generate point cloud data and that can not be measured except in bright daytime hours. For these reasons, laser scanner equipped UAV capable of measuring point cloud data at night and generating them in less time than UAV photogrammetry have been developed. However, since the accuracy of generation of point cloud data with the laser scanner equipped UAV varies depending on the conditions of the construction fields and the measurement method, it is necessary to realize the accuracy under various conditions. In this research, the measurement error of the UAV mounted laser scanner by the environment and measurement method are investigated and clarified at the viewpoint of the influence on the generation accuracy of each error factor in the sites of construction management. And the accuracy of generation of point cloud data with measurement method that takes measurement error into account is clarified.
