Description

 The Ministry of Land, Infrastructure, Transport and Tourism is examining application of aerial photogrammetry by UAV and ground-based laser scanners primarily to earthwork and concrete work. Although the laser scanner allows higher precision than UAV, it leaves invisible region with one-time measurement; therefore, it is necessary to make measurements more than once. Since superimposition of point cloud data acquired from laser scanners at multiple spots causes mixture of points with different degrees of precision at the same spot, it is required to devise a method for selecting highly precise points when creating three-dimensional models. This study intends to develop a technique for selecting point cloud data with highly precise in multipoint measurement using laser scanners, and evaluates the effectiveness of the proposed method through demonstration experiments.
