Abstract: A method for colourising a three-dimensional point cloud including surveying a point cloud with a surveying instrument. Each point of the point cloud may be characterised by coordinates within an instrument coordinate system having an instrument center. The method may include capturing a first image of the setting with a first camera. Each pixel value of the first image is assigned coordinates within a first camera coordinate system having a first projection center as origin and a first parallax shift relative to the instrument center. The method may include transforming the point cloud from the instrument coordinate system into the first camera coordinate system, resulting in a first transformed point cloud, detecting one or more uncovered points within the first transformed point cloud which are openly visible from the first projection center, and for each uncovered point, assigning a pixel value having corresponding coordinates in the first camera coordinate system.

The surveying device also includes an imaging unit including a camera sensor which is fixedly arranged so that an optical axis of the camera sensor is directed towards the rotation body, such that only in a predetermined imaging-alignment of the rotation body around the rotation axis (B) the optical axis of the at least one camera sensor is deflected by the curved deflecting element by a desired angle and direction so that the field of view comprises a defined field angle around the rotation axis (B).

Abstract: The invention relates to a method for correcting a distortion in an aerial photograph caused by a flight movement in the forward direction. The aerial photograph is captured by a surface sensor, the sensor lines of which sensor are exposed at different, successive exposure times, so that each individual sensor line senses a strip of terrain of the terrain flow over at the different exposure times. A relative flight altitude above the strips of terrain captured by the respective sensor line is assigned to the individual sensor lines. Furthermore, a compensation factor is separately determined for each of the individual sensor lines, wherein the factor depends on an air speed of the flying object, a focal length of the aerial camera and the relative flight altitude assigned to the respective sensor line, and corrects the distortion in the aerial photograph for the lines based on the respective compensation factor.

Abstract: The invention relates to a method for the geodesical measurement of an object (1), using a geodesical measuring appliance (2) comprising recording means (3) for acquiring a recorded image (4) at least of the object (1) to be geodesically measured.

A set of recorded image co-ordinates (7) are determined by establishing at least one set of associated display image co-ordinates (8), and the set of recorded image co-ordinates (7) is transformed into at least one geodesical measuring variable, especially a solid angle. Templates (10) which are in the form of models that can be placed on the display image and at least partially describe the object (1) are used to support the user during the fixing of the target point.
