Three-dimensional scanner of a pipe with tilt detection

The 3D quantitative measurement system for a sewer pipe is introduced. Two parallel lasers are rotated by the motor and draw the two annular streaks on the inside surface of the pipe. The circular laser streaks are recorded by the CCD camera. The measurement of the cross-section is established by analyzing the recorded streaks. The tilt of the robot against the axis of the pipe is detected by the deviation between two parallel lasers. It enables us to measure the vertical cross section of the pipe regardless the tilt of the system to the pipe. Experimental result shows the feasibility of the system.

Three dimentional measurement of fish movement using stereo vision

Recently, the technology of cultivation has been and continuous to be developed in the fisheries and the studies for a high production efficiency are widely conducted. The reaction of fishes under the sound should be studied in order to develop the fish tank with less factors of stress. In this paper, three-dimensional measurement system of the fish motion has been presented in order to study the relation of the fishes under the stimulating sound. Three kinds of fishes are used to detect the reaction against the sounds. Frequency analysis is executed by using the threedimensional position data. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008
