Abstract:

To provide a visual inspection device that can efficiently perform work, without deteriorating the image quality.

This visual inspection device is provided with a photographing means 63, which is constituted by assembling a plurality of cameras 62 together, so that the edge sections of their visual fields overlap each other, an image processing means 64 which prepares individual image data 73 for each camera 62, based on image signals 68 from the cameras 62 and synthesizes the image data 73 into a continuous assembled image data 74 corresponding to the arrangement of the cameras 62, and an image displaying means 65 which visualizes the assembled image data 74. This inspection device is also provided with a self-running mechanism, which moves the photographing means 63 along a surface to be inspected.
