THREE-DIMENSIONAL MEASURING DEVICE
To solve the problem in a measuring system using a laser scanner that the shape of a terrestrial object whose thickness is thin, such as a sign board installed beside a railway track, cannot be captured with certain accuracy.SOLUTION: A three-dimensional measuring device 1, mounted on a vehicle capable of traveling on a railway track, includes laser scanners 2a, 2b for acquiring a laser point group. Regarding the widthwise position of a railway track, the laser scanner 2a is at the position of one rail 32a and the laser scanner 2b is at the position of the other rail 32b. Regarding the extensional position of the railway track, the laser scanners 2a, 2b are at mutually different positions. The extensional component of direction vector of laser beams radiated in the same direction as seen from the extension direction of the railway track is in opposite directions between the laser scanner 2a and the laser scanner 2b.SELECTED DRAWING: Figure 3
【課題】レーザースキャナを用いた計測システムにおいて、線路脇に設けられる標識板などの厚みが薄い地物は形状を正確に捕捉しにくい。【解決手段】３次元計測装置１は鉄道の線路上を走行可能な車両に搭載され、レーザー点群を取得するレーザースキャナ２ａ，２ｂを有する。線路の幅方向の位置に関し、レーザースキャナ２ａは一方のレール３２ａの位置にあり、レーザースキャナ２ｂは他方のレール３２ｂの位置にある。線路の延伸方向の位置に関し、レーザースキャナ２ａ，２ｂは互いに異なる位置にある。線路の延伸方向から見て同じ方向に照射されるレーザービームの方向ベクトルの延伸方向の成分は、レーザースキャナ２ａとレーザースキャナ２ｂとで逆向きである。【選択図】図３
