1. A calibration apparatus comprising:

  • an obstacle detection unit that detects an obstacle on an arbitrary surface in a three-dimensional space in one of a plurality of images obtained by taking an image pickup subject from a plurality of directions, by using a transform parameter transforming a point on the surface into a point on the surface of other image, and computes position coordinates of the obstacle on each of the images; and

    a transform parameter adjustment unit that receives a distance data between an image pickup position and the obstacle, and adjusts the transform parameter with the received distance data and position coordinates of the detected obstacle, wherein the obstacle detection unit detects the obstacle by using the transform parameter adjusted by the transform parameter adjustment unit, and computes the position coordinates of the detected obstacle.
