内容記述タイプ Abstract
内容記述 A landslide gives the big loss to various structures. However, a detailed mechanism of a landslide is not understood completely. Ground based laser scanner is expected as useful measurement equipment for monitoring landslide. However, there are some problems in accurate measurement using the ground based laser scanner. Laser scanner data must be transformed into the ground coordinates using Ground Control Points (GCP). The prism is usually used for GCP. The ground coordinate of the prism is precisely measured by using GPS and Total station. However the acquisition of accurate coordinate of the prism in laser scanner data is very difficult. The error of the transformation showed maximum 10cm. This study focused on solving the problem in the geometric transformation. The accurate measurement of control points can be improved by measuring some flat surfaces. When three flat surfaces are measured, coordinates of the intersection in three planes can be calculated. This intersection can be used as a control point of the laser scanner data. This method should make accurate geometric transformation. Geometric transformation by using multi surface measurement was higher accuracy than geometric transformation using a prism. And, accuracy of geometric transformation showed less than 1cm.
