The camera part 20 is attached in the vicinity where the field apparatus 10 is installed, around a pipe P, or at such position for imaging the field apparatus 10 itself. The camera part 20 comprises an omnidirectional sensor or omnidirectional camera composed of a conical mirror, a hemispherical mirror, and a hyperbolic mirror, etc., and can image the peripheral environment for 360 degrees around the field apparatus 10 with the apparatus as the center. When imaging the field apparatus 10 itself, it is not required that it be attached or fixed tightly to the field apparatus 10 itself, and it may be installed at some distance from the field apparatus 10. <P>COPYRIGHT: (C)2004,JPO</p> |
