Abstract
The invention relates to a measuring system for optically measuring and imaging an environment, having a laser scanner for detecting measurement data, a processing unit for processing partial measurement data into processed measurement data, a display for displaying a portion of the processed measurement data representing at least a partial region of the environment. The laser scanner comprises an optical distance measuring device for detecting distance measurement data, having an emitter unit and a receiver unit, an imaging sensor for detecting image data, a base, a support rotatably fixed to the base about a support rotation axis, a beam deflection unit, a first angle encoder for recording first angle data about a rotation of the support about the support rotation axis, and a second angle encoder for recording second angle data about a rotation of the beam deflection unit about the beam rotation axis.
