Abstract: A computer-implemented method for the detection of scan reference markers within scan data provided by a laser scanner, wherein the scan reference markers are to be fixedly positioned within a scene and provide for a fixed absolute position reference in said scene. Therefore, the computer-implemented method comprises multiple steps. Firstly, the scan data is provided as a three-dimensional visual representation of a scene. Secondly, a first marker detection algorithm is applied to the scan data configured to identify scan reference marker candidates, wherein for each of the identified scan reference marker candidates a section in the scan data is defined. Further, a resolution enhancement algorithm may be applied to the defined section in the scan data, wherein the resolution enhancement algorithm is configured to obtain a comparably higher resolution of the defined section and provide a high-resolution section of the scan reference marker candidate.

Abstract: In some embodiments a scanning method for deriving information about surfaces of objects for a surveying system is disclosed. In some embodiments, the surveying system may include a control and evaluation unit with scanning functionality, such as, for example, a laser scanner or a total station. In some embodiments, the recorded point set of the detected object points is kept available in a volatile memory of the control and evaluation unit and by means of the control and evaluation unit as part of the scanning process an adaptation of the recorded point set is effected depending on at least one point density of the recorded point set. The adapted point set generated thereby, with loss of the recorded point set, is stored in a permanent memory.
