Definitions
- the present invention relates to a surveying system with active target objects according to the preamble of claim 1.
- laser measuring devices are used, which determine distances and directions (angles) of the target points.
- the laser measuring devices comprise a distance measuring device for distance measurement between the target point and the distance measuring device and an angle measuring device for measuring the diameter.
- the measurement of the target points is supported by target objects that are placed at the target points.
- the target objects are used in surveying systems with laser measuring devices that emit a search beam and a measuring beam, with the wavelengths for the search beam and the measuring beam advantageously differing.
- the measuring beam is used for the measuring task of the laser measuring device, for example for distance and / or angle measurement, and the search beam is used to find and identify the target objects.
- the search beam is greatly expanded in order to capture a larger spatial area, whereas a focused measuring beam is used for the measuring task.
- the target objects are subdivided into passive target objects that reflect the laser beam's search beam, and active target objects that do not reflect the search beam but emit a transmit beam.
- Active targets have the advantage that the laser gauge can distinguish the transmit beam due to a different wavelength of rays reflected from reflective surfaces.
- EP 1 734 336 A1 discloses an active target for a laser measuring device emitting an infrared search beam and a measuring beam.
- the target object comprises a reflector device with at least one reflector element for reflecting the measurement beam, a
- Receiving device with a receiving element for receiving the infrared search hls, a transmitting device with a transmitting element for emitting a visible or infrared transmitting beam, and a control device with an evaluation element for evaluating the received search beam and a control element for controlling the transmitting and receiving devices.
- a disadvantage of the target objects is that no identification and differentiation of the target objects is possible.
- the visible or infrared transmission beams have the same wavelength for several target objects in a surveying system.
- the object of the present invention is the development of a surveying system consisting of a laser measuring device and a plurality of active target objects, wherein the target objects for the laser measuring device are clearly identifiable and also distinguishable from the other target objects for the operator.
- the expenditure on equipment in the laser measuring device for identifying the target object should be as low as possible.
- the surveying system comprises:
- a first active target object with a first reflector means for reflecting the measurement beam, a first receiving means for receiving the search beam, a first transmitting means for transmitting a first visible transmission beam and a first control means for evaluating the received search beam, and for controlling the receiving and transmitting devices, and
- the light color of the second visible transmission beam is different from the light color of the first visible transmission beam.
- the advantage of identifying a target by means of a visible transmit beam is that unwanted reflections of the search beam, which is often formed as an infrared laser beam, are not detected on reflective surfaces such as mirror surfaces, safety vests, traffic signs, and license plates.
- the colored visible Transmission beam is detected by a camera device, the target object can be identified in the difference image of the camera device.
- different colored visible transmission beams can also be distinguished from each other by the operator of a surveying system.
- visible transmission beam includes a single visible laser beam, a plurality of visible laser beams that are emitted simultaneously but spaced apart from each other, and a plurality of visible laser beams that are emitted successively in time.
- the visible transmission beam is composed of a plurality of partial beams, which are spatially spaced or emitted one after the other.
- the surveying system has at least one further active target object with a reflector device, a receiving device, a transmitting device for emitting a further visible transmission beam and a control device, wherein the light color of the at least one further visible transmission beam is different from the light color of the first and second visible transmission beam.
- the light colors of the visible transmission beams and / or of the visible partial beams are preferably selected from the light colors red, orange, yellow, green, blue and violet.
- the six light colors red, orange, yellow, green, blue and violet are reliably distinguishable for the laser measuring device and the operator.
- the wavelengths of the visible spectrum are between approximately 380 and 750 nm. In the visible spectrum, six different light colors are distinguished: violet (380 to 420 nm), blue (420 to 490 nm), green (490 to 575 nm), yellow (575 to 585 nm), orange (585 to 650 nm) and red (650 to 750 nm).
- the light colors of the visible transmission beams and / or the visible partial beams are particularly preferably selected from the light colors red, green and blue.
- the light colors red, green and blue are particularly suitable for the visible transmission beams, as red, green and blue light-emitting diodes are available at low cost.

- FIG. 2 the structure of the active target objects in detail.
- FIG. 1 shows a measuring system 10 according to the invention consisting of a laser measuring device 11, a first active target 12 and a second active target 13 in a schematic representation.
- the target objects 12, 13 are in the embodiment of FIG. 1 attached to a pole or a staff and placed at the bottom of a room. In addition to attachment to a pole or a staff, the target objects can be attached to a wall or a ceiling.
- the laser measuring device 11 comprises a laser measuring device 14, a camera device 15 and a control device 16.
- the laser measuring device 14 has a first and second beam source, wherein the first beam source emits a search beam 17 and the second beam source emits a measuring beam 18.
- the search beam 17 serves to detect and identify target objects in the measurement environment. To operators and others in the

- the target object 20 may in the surveying system 10 of FIG. 1 as a first or second target object 12, 13 are used.
- an index "i" is used.
- the target object 20 comprises a reflector device 21 with a reflector element 22 for reflecting the measurement beam 18 and a target element 23 for aligning the measurement beam 18, a reception device 24 with four reception elements 25 for receiving the search beam 17, a transmission device 26 for emitting a visible transmission beam and a control device 27.
- the control device 27 has an evaluation element 28 for evaluating the received search beam 17 and a control element 29 for controlling the receiving and transmitting devices 24, 26.
- the transmitting device 26 comprises four monochrome beam sources 31, 32, 33, 34, which may be formed in the light colors red, green and blue.
- the beam sources 31, 32, 33, 34 are arranged in the four corners of the rectangular target object 20.
- the first beam source 31 emits a first visible partial beam 35
- the second beam source 32 a second visible partial beam 36
