ステレオ画像を使用する地形形状計測システム

抄録

We have developed a measurement system of the shape of the land using a stereo vision. When we use a stereo vision system to measure points in the image, we need to know the parameters for each camera. Usually, the camera parameters are calculated from a camera calibration technique, but it is difficult to apply to outdoor scenes. Our system calculates the camera parameters using the surveying instrument and makes the surface data of the land using a stereo ranging technique. In this paper, we describe the stereo vision system, the system configuration, the process of the measurement system of the shape of the land and an experiment to measure an actual slope.
