Outline of Final Research Achievements

The purpose of this research is to develop a compact moving body having an inertia measuring device moving in a pipe for estimating the shape of a scope camera or the like. The problem of this research was miniaturization of the inertial measurement device, its communication, the moving method inside the pipe, and its high accuracy. As for miniaturization of the inertial measurement device, it has been possible to downsize down to about 12 mm by using microcomputer with communication function, 6 axis gyro, lithium ion battery etc in recent years. We also devised a moving body shape that can measure at high speed without exceeding the measurement limit of the gyro. We also conducted experiments on image position estimation method, showed that the position estimation return function based on image retrieval is effective, and that robustness of position estimation by multiple maps is possible.
