摘要:
A finder apparatus which is used together with a photographing apparatus presents a marker for positioning (14a) for setting relative positions of the photographing apparatus and an object for calibration so as to be visually recognizable by an operator in a finder (12) configured to present an image of a subject so as to be visually recognizable by the operator, when photographing the object for calibration including at least one of a known shape and a known surface attribute in order to acquire parameters of a photographing optical system of the photographing apparatus.

摘要:
A calibration pattern unit which obtains correction information of an imaging system by imaging at the imaging system (6) comprises a calibration pattern (5-1) which has a known geometric pattern formed on a plurality of three-dimensionally arranged planes, and a relative position and posture fixing section (7) which fixes relative position and posture between the calibration pattern (5-1) and the imaging system (6).
摘要:
A calibration apparatus which estimates a calibration parameter of an image acquisition apparatus (14), comprises a calibration jig (10) which includes at least two planes and in which calibration markers having known three-dimensional positions are arranged in each plane based on a predetermined rule. The calibration apparatus further comprises a calibration marker recognition section (12) configured to measure and number in-image positions of the calibration markers in at least one image obtained by photographing the calibration jig by the image acquisition apparatus, and a parameter estimate section (12) configured to estimate the calibration parameters of the image acquisition apparatus by the use of the three-dimensional position and the in-image position of the calibration markers numbered by the calibration marker recognition section.
