A geodetic surveying device, wherein the geodetic surveying device is configured for surveying retroreflective cooperative targets, the geodetic surveying device comprising a base, a telescope and a support. The geodetic surveying device further comprises a target recognition emitting unit, called ATR-illuminator, an target recognition sensor, called ATR-sensor, an angle encoder and a processing unit. The geodetic surveying device is configured to distinguish desired targets from undesired targets, wherein the geodetic surveying device further comprises a classification model, wherein the classification model is configured for classification of retroreflective targets generating spots, wherein the retroreflective targets are classified into desired targets and undesired targets, wherein the classification is carried out by applying the classification model on the spot.

Surveying device for improved target classification

A method for scanning an area using a ground penetrating radar (GPR) by moving the GPR along at least one scanning trajectory. The method includes determining at least one landmark object image feature by applying object detection techniques to images of the area to be scanned, determining a position and/or type of at least one landmark object corresponding to the at least one landmark object image feature in a scanning-area coordinate frame, determining a candidate position or candidate type of at least one candidate underground asset in the area to be scanned by using the determined position or type of the at least one landmark object determining the at least one scanning trajectory using the candidate position and/or candidate type of the at least one candidate underground asset.

GPR scanning through the use of external scene knowledge

A computer program product and to a method for compensating thermal errors in a mechanical process, the mechanical process in particular provided by a mechanical device such as a coordinate measuring machine, a tooling machine or an articulated robot arm. Thermal errors arise due to thermal disturbances affecting the mechanical process, wherein thermal disturbances may arise from environmental influences affecting the mechanical process or from internally generated changing temperature distributions.
