Title: Filler metal installation position checking method and filler metal installation position checking system

Abstract: The present invention is a filler metal installation position checking method and a filler metal installation position checking system for confirming difference between installation position and designed position of a filler metal embedded in a wall surface. A standard surface target 16 having known actual dimension and position to a wall surface 12 is provided to the wall surface 12 where a filler metal 14 is installed. The wall surface 12 is photographed together with the standard surface target 16 to create image data 18. Using actual position and dimension of the standard surface target 16 and position and dimension of the standard surface target 16 on an image displayed by the image data 18, the image data 18 is converted into corrected image data 20 displaying an image corrected in a manner that the image is photographed from front of the wall surface. Design CAD data 22 showing actual designed position of the filler metal is read out and the images shown by the corrected image data 20 and the design CAD data 22 are outputted as images on one same display.
