    Abstract: PROBLEM TO BE SOLVED: To verify whether or not camera calibration is accurately performed.SOLUTION: An appropriate position Qi on a photographic image is specified by the operation of a mouse 18 for instance. Then, an image coordinate value (u, v) of the specified position Qi is converted to a coordinate value of world coordinates set to a real space. At the time, it is converted to the world coordinate value on a plane where the height in the real space is zero. Further, the world coordinate value is converted to a two-dimensional coordinate value (α, β) on a map image which is a simulated image of the plane. Then, a marker 46 is displayed at a position Qj according to the two-dimensional coordinate value (α, β) on the map image. When the position Qj of the marker 46 corresponds to the specified position Qi on the photographic image, it is defined that the camera calibration is accurately performed.

    Abstract: PROBLEM TO BE SOLVED: To easily recognize the height and the position of a photographing target point in a three-dimensional space.
    SOLUTION: A three-dimensional photographing area including a floor surface 4 is imaged by one master camera 2. On the basis of an image pickup signal of the master camera 2, a two-dimensional imaging screen of the photographing area is displayed on a display device 10. Two-dimensional coordinate positions (U1, V1) which are coordinates, on the two-dimensional picture, of an object on a reference two-dimensional area 4a corresponding to the floor surface 4 on the two-dimensional picture are designated by a mouse of an operation part 14. The two-dimensional coordinate positions (U1, V1) are transformed into first three-dimensional coordinate positions (xw, yw, 0) on the three-dimensional space by a personal computer 8. The height of the object from the floor surface 4 in the three-dimensional space is set by operating the mouse of the operation part 14, and an operation pointer 16 is displayed at that set position.
