This research aims at construction of a highly accurate three-dimensional environmental map. In recent years, the compact and inexpensive RGB-D camera is used in various fields, and is applied also to sensing of the autonomous mobile robot. Generally, RGB-D camera is used for motion recognition of human beings, such as motion capture, and these applications do not need accuracy. Because the depth information of RGB-D camera is not accurate, it is unsuitable for highly accurate measurement to use. Therefore, distortion occurs on the three-dimensional environmental map constructed using RGB-D camera. We considered the calibration method of RGB-D camera for the purpose of acquiring accurate depth information.
