A system and a method are provided that prevent a wrong panel of a structure such as an aircraft from being opened for inspection of an interior of the structure. A system includes a computer, a portable terminal and a camera configured to capture an image of a structure with panels attached to generate a first image and capture another image of the structure with a predetermined panel among the panels removed to generate a second image and configured to send the first image and the second image to the computer. The computer combines the first image and the second image to generate a third image and sends the third image to the portable terminal. The portable terminal displays the third image. In the third image, the predetermined panel is translucently shown with at least one component at an interior of the predetermined panel being seen through.
