Abstract
A three-dimensional image capturing device obtains distance information of a standard subject, to which the distance from the device to each point of a surface of the standard subject is known. Based on the distance information of the standard subject, correction data is sensed, which is an error of distance information sensed when using a measurement subject, to which the distance from the device to each point of a surface of the standard subject is unknown. A distance measurement is performed for the measurement subject, so that distance information is obtained. The distance information of the measurement subject is corrected using the correction data.
