A spherical camera inspection system was proposed for low-cost and efficient nondestructive inspection of tubular infrastructure. A transparent capsule-shaped inspection device with a built-in omni-directional camera was developed and rolled into a pipe. The inspection device rolls inside the pipe and captures images of the inner wall of the pipe as it moves. The obtained omni-directional images are image-processed to create a development map of the inner wall of the pipe. Verification experiments were conducted on the proposed system. The inside of a simulated pipe was photographed with a prototype inspection device, and a development map of the pipe inner wall surface was created. As a result, it was confirmed that the proposed system can produce appropriate development maps.
