Abstract:
A calibration apparatus calibrating a projection apparatus projecting a projection image includes a captured image acquiring unit acquiring a captured image at each change of at least one of a relative position between the projection apparatus and a plane body and a relative posture between the projection apparatus and the plane body, a reflection position estimating unit acquiring reflection positions at each change of at least one of a position of the plane body and a posture of the plane body using a predetermined correspondence relationship between a pixel of the captured image and a position on the plane body, a plane body position posture estimating unit estimating positions and postures of the plane body so as to minimize a degree of misfit of the reflection positions from a straight line of the reflection positions, and a projection light beam identifying unit identifying an equation of the light beam.
