Abstract
A laser measuring system is provided by combining N-beams, angle based modulation and a laser receiver and laser transmitter configured with corner reflectors for signal shift measuring to facilitate full three dimensional positioning.
Claims29
A laser receiver comprising:
- a photo detection unit for receiving a plurality of modulated laser beams, each laser beam of the plurality of laser beams being modulated with at least azimuthal angle information;
- and
- a processor for estimating an azimuthal position, associated with the laser receiver, using particular ones of the plurality of modulated laser beams.
A position measuring method for a laser receiver, the method comprising:
- receiving a plurality of modulated laser beams, each laser beam of the plurality of laser beams being modulated with at least azimuthal angle information;
- and
- estimating an azimuthal position, associated with the laser receiver, using the plurality of modulated laser beams.
A non-transitory computer-readable medium storing computer program instructions for position measuring by a laser receiver, the computer program instructions, when executed on a processor, cause the processor to perform operations comprising:
- receiving a plurality of modulated laser beams, each laser beam of the plurality of modulated laser beams being modulated with at least azimuthal angle information of a laser transmitter that transmitted the plurality of modulated laser beams;
- estimating an azimuthal position of the laser receiver using the plurality of modulated laser beams;
- and
- estimating a distance between the laser receiver and the laser transmitter using at least one modulated laser beam which has been reflected between the laser receiver and a laser transmitter that transmitted the plurality of modulated laser beams.
