Embodiment Construction

[0043] figure 1 A stationary measuring device 90 is shown having a scanning function (for example in the form of a laser scanner) for recording a target surface 100 . The device is here configured to emit measurement radiation 91 according to a specified measurement direction 1 , to receive measurement radiation 91 reflected by said surface 100 , and to evaluate it, for example using time-of-flight or phase difference methods. In order to scan the target surface 100, the measuring radiation 91 is continuously translated and in each case at least one measurement value (including in each case the distance from the corresponding target point P) is recorded continuously at short time intervals, As a result, a plurality of measurement directions 1 are obtained and a plurality of points 98 of the target surface 100 are measured, thereby obtaining a plurality of individual measurement data items which are interconnected and form scan data. Measuring direction 1 for example by elevat...

Abstract

The invention provides a method for visually representing scanning data which are composed of a multiplicity of individual measurement data. The individual measurement data in each case have at leastone measurement value that is linked to a respective measurement direction, wherein the measurement directions are different from one another such that a predetermined scanning region with a predetermined scanning resolution is covered. The representation of the scanning data is effected by way of an image map with a number of map points that is dependent on a predetermined display resolution andby way of an assignment rule for assigning measurement value to map point, wherein the assignment is effected immediately on the basis of the respective measurement direction that is linked to the measurement value.

Description

technical field [0001] The invention relates to a method for visually representing scan data according to the preamble of claim 1 and to a scanning-capable measuring system having the preamble of claim 15 . Background technique [0002] 3D scanning is a very efficient technique for generating millions of individual measurement data points (especially 3D coordinates) within minutes or seconds. Typical measurement tasks are the documentation of objects or surfaces of objects such as industrial installations, building facades or historic buildings, as well as accident and crime scenes. Measuring devices with scanning functionality are eg total stations and laser scanners (such as Leica P20 or Leica Multi Station 50) for measuring or creating 3D coordinates of surfaces. For this purpose, they must be able to direct the measuring beam (usually a laser beam) of the distance measuring device onto the surface and, in this way, acquire the directions of the corresponding measuring p...
