The invention relates to a laser-assisted measuring system for three-dimensional objects and complex surfaces. In accordance with the invention, three-dimensional objects are preferably interior areas of buildings or geological hollows with complex surfaces. The invention makes a considerable contribution to the rationalization and improvement of precision in measuring operations of this kind. In the known pulse operation time method, the distance is measured by a laser pulse from the transmitter to the measuring point and back. A measurement fan is generated on emission of laser pulses. In accordance with the invention, the measurement fan (11) must be turned 360° step by step at a constant speed, in order to cover a three-dimensional area. In a wall, up to 200,000 measuring points can be obtained. An appropriate evaluation of the measurement data takes place so that a 3D wire model can be constructed. |
