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. Once the angular orientation of a coverage strip (5) of the recording means (3) has been determined, the image (4) is captured and represented at least partially in the form of a display image (6). 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. Once the template (10) has been selected and positioned, it is adapted to the recorded object (1a) and determines the set of recorded image co-ordinates (7) by means of a characteristic point (11) of the template (10). The invention also relates to an electronic display and contr…
