Abstract
A method for processing scan data which are recorded by a measuring device with a scan functionality, wherein a reduced scan data record is created from a recorded scan data record with a first scan data density by selecting individual scan data points. Here, the selection represents an adaptation to a reduced scan data density, which is less than the first scan data density of the recorded scan data record. The reduced scan data density depends on a predetermined display resolution for displaying scan data. The reduced scan data record is transmitted to an external data processing device and displayed by the latter by means of a display, depending on the predetermined display resolution.

A method for processing scan data, the method comprising:
- recording first scan data record over a defined object surface scan region by a measuring device, wherein the first scan data record comprises a first number of individual scan data points with a first scan data density and the individual scan data points are respectively related to a point on an object surface;
- creating a reduced scan data record with a second, reduced number of individual scan data points making a selection from the first number of individual scan data points of the recorded scan data record using a control and evaluation unit of the measuring device, wherein the selection is carried out as an adaptation to a predetermined second, reduced scan data density, which is lower than the first scan data density, and the reduced scan data density is dependent on a predetermined display resolution for visually displaying scan data;
- transmitting the reduced scan data record from the measuring device to an external data processing device;
- and
- visually displaying the reduced scan data record or of parts thereof on a display of the external data processing device with the predetermined display resolution or with a display resolution derived therefrom.
A measuring system comprising:
- a measuring device with a scan functionality for recording first scan data record over a defined object surface scan region, wherein the first scan data record comprises a first number of individual scan data points with a first scan data density and the individual scan data points are respectively related to a point on an object surface;
- and
- a data processing device that is external to the measuring device, the data processing device configured to:
- create a reduced scan data record with a second, reduced number of individual scan data points making a selection from the first number of individual scan data points of the recorded scan data record using a control and evaluation unit of the measuring device, wherein the selection is carried out as an adaptation to a predetermined second, reduced scan data density, which is lower than the first scan data density, and the reduced scan data density is dependent on a predetermined display resolution for visually displaying scan data,
- transmit the reduced scan data record from the measuring device to an external data processing device, and
- visually display the reduced scan data record or of parts thereof on a display of the external data processing device with the predetermined display resolution or with a display resolution derived therefrom.
