PROBLEM TO BE SOLVED: To provide a wide area surface imaging device capable of easily discriminating at which position of an actual building a crack occurs even when the number of pixels of an imaging surface is made large.SOLUTION: With a wide area surface imaging device, a camera group in which a plurality of cameras are arranged in a predetermined physical relationship images a continuous wide area imaging surface and includes a horizontally overlapped imaging area where the imaging surface of each adjacently arranged camera overlaps with each other and laser pointer means for radiating laser pointer light onto the horizontally overlapped imaging area.SELECTED DRAWING: Figure 1 |
