Abstract
Excavation is performed using an excavation device so that positions of a bucket and of an excavated material are measured with high accuracy. Safe excavation work is realized by having the excavation device include a stereo camera, and by recognizing a bucket from an image photographed by the camera, measuring a position of the bucket, recognizing an excavated material to be separated from the ground from the image photographed by the camera, measuring a position of the excavated material, and measuring a positional relationship between the bucket and the excavated material in the same screen.
