Claim Text:
1. A measuring device comprising: a measuring unit configured to irradiate an object with a plurality of light beams, and measure, for each light beam, a direction of an irradiated point on the object, a distance to the irradiated point, and reflection intensity of the irradiated point; a capturing unit configured to capture the object that has been irradiated with the light beams and obtain an image; an estimation unit configured to estimate, for each irradiated point, an estimated projection position on the image where the irradiated point is to be projected, using the direction and the distance of the irradiated point and calibration information based on calibration of the measuring unit and the capturing unit performed in advance; a calculator configured to a detector configured to detect a calibration shift between the measuring unit and the capturing unit by comparing the reflection intensity change point and the brightness change point.
