Finde fotogrammetrie Photogrammetry is, in general, a technology to calculate 3-dimentional coordinates of an object by analyzing the features on the overlapping photographs of the object. If less features on the object, it will be hard for algorithm to calculate the pose of the camera and the 3d information of the object If using manual mode, set the aperture to as high a number as you can, certainly above 10; this will maximise the depth of field (avoiding close parts and far parts looking blurry). Also, if using a black background, decrease exposure (and vice versa for a white background). This will remove all detail from the background Adjusting The Scanner's Position In Relation To the Object. Sometimes doing slight adjustments in the way you scan an object can have a big impact on your results. When scanning shiny surfaces, scan at a slight angle and distance. Light then diffuses instead of bouncing directly back into the 3D scanner which is the source of the problem
