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

Surveying apparatus comprising an event-based camera comprising a dynamic vision sensor. The events detected by the camera are used, by means of target radiation, to determine a direction to a target to be surveyed or to determine camera poses of the camera in the context of visual odometry or determining the location of the surveying apparatus

Surveying apparatus comprising event-based camera

The invention generally relates to an industrial or geodetic surveying device having a tracking unit configured to receive over a tracking channel a tracking signal which is used to track a cooperative target. According to the invention, the surveying device comprises a camera to generate image data, wherein based on the additional knowledge about the position of the cooperative target in an image generated in the locked state, the visual appearance of the target carrier is learned and the result is stored in the form of a detector for use in a backup tracking mode.

Surveying device with automatic training of locked object or person for camera based target tracking

The invention relates to a surveying system for surveying and tracking a mobile target object which defines a target point, wherein the surveying system has a control and evaluation unit, a surveying device with a sighting device which defines a target axis, and a target object. The control and evaluation unit is designed to track the moving target object within the scope of a target-finding functionality, wherein a first change in alignment of the target axis about a first axis occurs as a function of detected target-finding radiation in such a way that the target axis tracks the movement tendency of the target object.

Device for automatically finding a mobile geodetic target object

Measuring device with a control and evaluation unit, a radiation source for emitting an illumination light ray and a fine targeting and target tracking functionality, a variation of the emission of the illumination light ray being effected automatically controlled by the control and evaluation unit, in the course of the fine targeting and target tracking functionality, such that a known sequence of illumination ray flashes is generated.
