Camera position / orientation evaluation apparatus, camera position / orientation evaluation method, and camera position / orientation evaluation program

摘要

There is provided a camera position posture evaluating device which can calculate a value which indicates an evaluation of a state of a camera from a viewpoint of to what degree an object appears in an image suitably for image processing. A resolution evaluating means 71 calculates a first suitability rate matching each position in a target area from a viewpoint of resolution. A gazing point angle evaluating means 72 calculates a second suitability rate matching each position in the target area. A target area evaluating means 73 calculates a third suitability rate from a viewpoint of how a target object field-of-view area and the target area overlap. A comprehensive evaluating means 74 calculates an evaluation index which indicates to what degree the state of the camera is suitable to the image processing based on the first suitability rate matching each position in the target area, the second suitability rate matching each position in the target area and the third suitability rate.
