<p>PROBLEM TO BE SOLVED: To make it possible to correctly conduct a coordinate transformation and to accurately detect a target by imaging a chart installed in the vicinity of an imaging unit and a dummy target installed at a remote distance, and measuring the corresponding point between the imaging units. SOLUTION: A corresponding point chart 14 is disposed at a predetermined position, imaged by imaging units 1a, 1b, and one picture content is stored. Then, remote dummy target 15 is imaged by the units 1a, 1b except the chart 14, and further the one picture content is stored. There is the positional deviation corresponding to the interval D between the units 1a and 1b in the coordinates obtained from the picture obtained by imaging the chart 14 when the target is disposed at a sufficiently remote position, it can be transformed to the true corresponding point coordinates by using the positional coordinates of the target 15 imaged at the second times. The true corresponding point coordinates are obtained from the coordinates obtained from the picture imaged from the chart 14, the positional coordinates of the target 15 imaged by the unit 1a, and the positional coordinates of the target 15 imaged by the unit 1b.</p> |
