Abstract:
It is an object of the present invention to provide a measuring apparatus capable of easily restoring the tracking state when the tracking state of the target is interrupted. One aspect of the present invention is a measuring apparatus that emits a light beam toward a target, captures and tracks the target, and measures the three-dimensional coordinates of the target. The measuring apparatus includes: a light source for emitting light beam; an angle control unit for controlling the emission angle of the light beam emitted from the light source so as to track the moving target; an imaging unit for capturing the target or the vicinity of the target, and a recognition unit for recognizing the target or the specific portion including the target from an image captured by the imaging unit. The angle control unit controls the emission angle of the light beam so as to emit light beam toward the target or the specific portion including the target recognized by the recognition unit when the tracking of the target is released.
