1. An apparatus for detecting a position in an actual space of an object by imaging said object with an imaging unit, comprising:

  • said imaging unit for obtaining an image of a plurality of objects;

    a corrective coefficient calculating unit for calculating a corrective coefficient to correct projected coordinates of said objects imaged by said imaging unit; and

    a correcting unit for correcting said projected coordinates of said objects by using said corrective coefficient calculated by said corrective coefficient calculating unit, wherein said corrective coefficient calculating unit calculates said corrective coefficient based on a distance between said objects, and a distance from said imaging unit to said objects.
