<p>PROBLEM TO BE SOLVED: To easily and accurately specify an irradiation target position even if an inexpensive general machine is used by obtaining and storing positional coordinates based on angle information obtained by capturing an irradiation target with an image pickup device and calculating image pickup axes and positional coordinates based on this stored information and the angle information. SOLUTION: An irradiation target M is captured by image pickup devices 2 and 3 such as first and second television cameras, and angle information regarding pan and tilt axes Pt and Pt2 orthogonal to each other in the axial point position coordinate of image pickup axes 2a and 3a obtained by rotary base driving devices 4 and 5 thereof is stored in a storage section 6. Then, by using the angle information of the image pickup directions of the image pickup devices 2 and 3 obtained by the rotary base driving devices 4 and 5 and each axial point position coordinate stored in the storage section 6, straight lines indicating the image pickup axes 2a and 3a are specified by a straight line calculation processing device 7. Then, with a coordinate calculation device 8, an irradiation target coordinate proximate one point on a line which is a shortest distance between the specified straight lines. By using this coordinate, an irradiation rotary base driving device B is controlled and an irradiation target M is irradiated by a sport light lamp body A.</p> |
