Abstract:
1. A laser scanner for optically scanning and measuring an environment, the laser scanner comprising: a light emitter, a rotary mirror, a receiver lens, and a light receiver, the light emitter configured to emit an emission light beam at an emission wavelength, the light receiver configured to receive a reception light beam, the emission light beam being reflected by the rotary mirror to an object in the environment, a portion of the emission light beam being reflected by the object to produce the reception light beam, the reception light beam being reflected by the rotary mirror and passing through the receiver lens, the receiver lens having an optical axis; a color camera on the optical axis of the receiver lens, the color camera responsive to visible wavelengths and configured to take colored pictures of the environment; a dichroic beam splitter and an energy detector, the dichroic beam splitter configured to pass a first wavelength of electromagnetic energy to the energy detector and to pass the reception light beam at the emission wavelength to the light receiver, the first wavelength being different than the emission wavelength and different than the visible wavelengths received by the color camera; and a control and evaluation unit configured to determine, for a multitude of measuring points, a distance to the object based at least in part on the reception light beam, the control and evaluation unit further configured to link the distance to the colored pictures and to the electromagnetic energy received by the energy detector.
