We have been studying the high-precision three-dimensional measurement system using cameras. In this paper, our system is verified, and its application is reported. The principle of our measurement system is based on the stereo measurement. In our system, reducing the quantization error by numerical processing can realize the highprecision 3D measurement at the long distance. This measurement system has many applications, such as industrial use, ITS, robotics, and many others. Our system has been applied on the observation of the glacier. The Perito Moreno glacier, which is our target, moves very fast and the moving speed is reported as about 2 m/day. Then, it is thought that the important information about the global warming can be obtained by observing this glacier. But, as the width of the glacier is several km, there were no reports of continuously observing the movement of the glacier in high accuracy. As a result, the unique observation results about the daily movement of the glacier were measured. The observation of the glacier flow was carried out for the third straight year. In this paper, the valuable results of the glacier observation and experimental results to verify the precision are discussed.
