Abstract

An optical axis angle inspection device is provided with a first camera and a screen which are disposed in front of a laser distance meter, is provided with a point light source on the screen, and is provided with a second camera disposed behind the laser distance meter. An image of the laser distance meter is captured by the first camera, and the height of the point light source is fitted to the height of the laser distance meter on the basis of the captured image. Then, an image of the point light source is captured by the second camera, and a difference in height between the centroid of the captured image and the point light source is specified. The optical axis angle of the laser distance meter is calculated from the difference in height and the distance from the screen to the laser distance meter.
