摘要： The invention relates to an electro-optical distance-measuring device, more particularly a laser rangefinder, with a transmitting unit for transmitting intensity-modulated optical radiation, a receiving unit for receiving a portion of the optical radiation reflected back from a target in a photosensitive electrical component and converting it into an electrical received signal, an input filter for filtering the received signal, an analogue-to-digital converter for digitising the filtered received signal and an electronic analysis unit that calculates the distance from the rangefinder to the target object on the basis of a signal propagation time using the digitised received signal. The input filter is implemented as a time-discrete and continuous-value filter structure, more particularly a digital filter structure.

摘要： The invention concerns a device for calibrating distance-measuring apparatus. A transmitter (1) emits high-frequency modulated optical radiation which is reflected by an object to be measured and is received by a measurement receiver (2). Part of the transmitter radiation is always decoupled as reference radiation and guided via a calibration path to a reference receiver (3) whose electrical signals are fed to a frequency mixer (4). The frequency mixer (4) and the avalanche photodiodes acting as measurement receivers (2) of the measuring radiation are interconnected directly via an electrical connection line (5) upon which a mixer frequency acts. As a result thereof, optoelectronic calibration which completely compensates the temperature-dependent phase shifts of the avalanche photodiodes is possible. Since, in addition, the phase shifts generated in the reference and receiver signals by the temperature drifts of the transmitter (1) compensate one another, the overall accuracy of the distance measurement is increased, in particular for short measuring times and immediately after the apparatus has been switched on. Furthermore, in comparison with a successive mechanical calibration process, the measuring times are halved and advantages in terms of weight, cost and reliability are afforded since a mechanical change-over device is dispensed with.

摘要： The equipment (10) has an evaluation and control unit connected with a laser source, a laser light detector and angle blades. The evaluation and control unit automatically controls user-side selected lines. A virtual surface is defined by a selected line and as a vertical preset direction. A subset of space points (1-4) is selected from a space point amount, which lies within a buffer zone surrounding the defined virtual surface. An elevation representation of the space points belonging to the subset is indicated on a display. Independent claims are also included for the following: (1) a method for representation change from a view representation or a spatial representation to an elevation representation (2) a computer program product comprising a program code for executing a method for representation change from a view representation or a spatial representation to a elevation representation (3) a system of a structure surveying equipment for surveying of spatial points of an indoor of a building.
