Abstract
Disclosed herein are separated type receiving device for lidar, transmitting device for lidar and lidar system thereof. The receiving device for Lidar is installed in a moving device and separated from a transmitting apparatus for Lidar fixed to a fixed body. The receiving apparatus for Lidar includes: an object beam detection module configured to detect an object beam which is a beam received after being transmitted from the transmitting apparatus for Lidar and reflected from a neighboring object of the moving device; and a reception controller configured to generate Lidar data based on information associated with the transmitted beam and a signal of the object beam.
Claims17
A receiving apparatus for Lidar installed in a moving device and separated from a transmitting apparatus for Lidar fixed to a fixed body, the receiving apparatus for Lidar comprising:
- an object beam detector configured to detect an object beam which is a beam received after being transmitted from the transmitting apparatus for Lidar and reflected from a neighboring object of the moving device;
- and
- a reception controller configured to generate Lidar data based on information associated with the transmitted beam and a signal of the object beam,
- wherein the reception controller is further configured to:
- obtain an intensity of light according to the object beam and a reception time of the object beam, based on the signal of the object beam, and
- generate the Lidar data, based on the intensity of light, the reception time and the information associated with the transmitted beam.
A Lidar system comprising at least one transmitting apparatus for Lidar and a receiving apparatus for Lidar that are operated in separation from each other,
- wherein the transmitting apparatus for Lidar is installed to be fixed to a fixed body and comprises:
- a light emitter configured to output a light;
- a beam scanner configured to outwardly irradiate the output light as a beam;
- and
- a transmission controller configured to control the light emitter and the beam scanner, and
- wherein the receiving apparatus for Lidar is installed in a moving device and comprises:
- an object beam detector configured to detect an object beam which is a beam received after being transmitted from the transmitting apparatus for Lidar and reflected from a neighboring object of the moving device;
- and
- a reception controller configured to generate Lidar data based on information associated with the transmitted beam and a signal of the object beam.
A receiving apparatus for Lidar installed in a moving device and separated from a transmitting apparatus for Lidar fixed to a fixed body, the receiving apparatus for Lidar comprising:
- an object beam detector configured to detect an object beam which is a beam received after being transmitted from the transmitting apparatus for Lidar and reflected from a neighboring object of the moving device;
- a transmit beam detector configured to detect a beam transmitted directly to the receiving apparatus for Lidar as a transmit beam among beams of the transmitting apparatus for Lidar;
- and
- a reception controller configured to generate Lidar data based on information associated with the transmitted beam and a signal of the object beam,
- wherein the transmit beam detector is further configured to identify at least one of an irradiation direction of the transmit beam, an angle of the transmit beam, an emitting position of the transmit beam, an emitting time of the transmit beam and an emitting repetition rate of the transmit beam, and
- wherein information obtained from the transmit beam is beam scan information that includes at least one of the irradiation direction, the angle, the emitting position, the emitting time and the emitting repetition rate.
