摘要： PROBLEM TO BE SOLVED: To provide a system for investigating a wall surface of a structure, which creates an expansion image with an approximately uniform contraction scale for the whole wall surface of the structure and can acquire image data sufficient to estimate a deterioration state of the surface of a conctrete structure appropreately. SOLUTION: In the system, a plurality of video cameras 1 opposite to the wall surface 10 are installed on a camera mount table 4 so that the plane on which the video cameras are installed is approximately normal to the wall surface 10, and distances up to the wall surface 10 are identical to each other, and edge portions of view field of adjacent video cameras 1 overlap each other. Then, the wall surface 10 is photographed by moving a measuring vehicle 3 while keeping the distance up to the wall surface approximately constant. An wall image with the uniform contraction scale can be formed because of above such installing condition or the like that video cameras 1 are opposite to the wall surface 10. Furthermore, even in the case that the overlap rate of the images is low, or the scale of the image is varied because of changing the distance between the photographing means and the surface, measurement data by an INS, an odometer or a laser scanner is utilized to a connection process, and thereby enabling to create the expansion image with the uniform contraction scale.

摘要： PROBLEM TO BE SOLVED: To measure three-dimensional position coordinates of a moving body such as predatory birds or the like. SOLUTION: A measuring instrument A and a measuring instrument B are arranged on the positions separated, for example, by about 10 m on a place in the mountains, and the moving body 10 is photographed by two video cameras 1, 2. When the moving speed of the moving body 10 is over a prescribed value or the moving body 10 moves to the edge of a screen, personal computers 5, 6 control azimuths and angles of elevation of the video cameras so that the moving body 10 is displayed in the center of the screen. Only when the moving body 10 is acquired, data such as the azimuths and the angles of elevation of each video camera, the coordinates on the image of the moving body 10, the time or the like are preserved. Equations of two straight lines joining the moving body 10 to the video camera 1 and joining the moving body 10 to the video camera 2 are calculated by using the preserved data. When the distance between the two straight lines and middle point coordinates are in a prescribed range, the middle point coordinates are preserved as the three-dimensional coordinates of the moving body 10.
