PURPOSE: To make the coordinate system of a television camera coincident with the coordinate system of a table by correcting the fitting angle of the television camera from the locus of a point on a screen when the table is moved.

CONSTITUTION: The locus of an observation object point is obtained by moving a relative position moving device 9 via an operating device 5 and a relative position controller 8 so as to move the relative position of the table 1 to the TV camera 2 in the Z axis direction. Thus, the operating device 5 operates the corrective operation of the fitting angles θ2, θ3 so as to correct automatically the fitting angle of the camera 2 via a camera attitude controller 6 and a camera rotating device 7. Then the relative position of the table 1 is moved in an axis X or Y similarly to the axis Z so as to obtain the locus of the observation object points. The corrective operation of the angle θ1 is conducted similarly so as to correct automatically the fitting angle of the camera 2. Thus, the coordination system of the television camera and the coordination system of the table are made coincident together.
