摘要： Detection of a target by a surveying device is automated to achieve simple work. A surveying method uses a surveying device for detecting and identifying a target device having an entire circumference reflection prism and a code display that is arranged in a vertical direction. The surveying device has a laser scanner configured to perform laser scanning along a vertical plane while horizontally rotating. The surveying method includes performing laser scanning by emitting laser scanning light along the vertical plane while making the surveying device horizontally rotate, and detecting the code display on the basis of the laser scanning light that is reflected back.

摘要： An absolute encoder includes a light-emitting mechanism including a light-emitting surface and emitting detection light from the light-emitting surface. A light-receiving mechanism including a scale plate having a scale area and receiving at a light-receiving area the detection light emitted from the light-emitting surface and passing through the scale area of the scale plate. The light-emitting mechanism and the light-receiving mechanism are set to a positional relationship that inclines an irradiation axis extending from the light-emitting surface through the scale area to the light-receiving area relative to a rotation axis direction of the scale plate.

摘要： Novel tools and techniques that can be used to enhance the effectiveness of photogrammetric tools, such as bundle adjustment. One set of techniques can include a photo-observable backsight operation, in which a position of target point can be observed non-photographically, and this observed position can be used to constrain a pixel coordinate location of the same target point in a bundle adjustment operation. Using another technique, a photo-observable check shot operation, the observed position of another target point can be used to verify the validity of a bundle adjustment calculation. Such techniques can be used together or separately.

摘要： A measuring appliance in which inputted or measured spatial points and a horizontal projection representation or spatial representation of at least some spatial points from the quantity of spatial points can be displayed, said points being at least partially connected by lines. The measuring appliance has a representation-changing functionality in the framework of which, according to a line selected on the user side from the lines displayed in a horizontal projection representation or a spatial representation, in an automatically controlled manner by means of the evaluation and control unit: a virtual surface is defined by the selected line and a direction provided as the vertical; a subset of spatial points is selected from the quantity of spatial points, lying inside a buffer zone surrounding the virtual surface in a defined manner; and a vertical projection representation of exclusively such spatial points pertaining to the subset is displayed on the display.
