Abstract

The invention discloses a transceiving combine lens based two-dimensional scanning laser ranging radar and mainly solves problems of large size and low space utilization rate of scanning laser radar in the prior art due to separated placement of a transmitting part and a receiving part. The transceiving combine lens based two-dimensional scanning laser ranging radar comprises a receiving sensor, alaser, a combined lens and a rotating reflection component in sequential arrangement. The laser is used for lasing, the combined lens is used for collimation of emitted laser and convergence of received laser, the transmitting component is capable of rotating during lasing, and the receiving sensor is used for receiving laser. By adoption of the technical scheme, the problems are well solved, andthe transceiving combine lens based two-dimensional scanning laser ranging radar can be used for laser ranging radar.

Description

technical field [0001] The invention relates to a two-dimensional scanning laser ranging radar based on a combined transceiver lens. Background technique [0002] Lidar is an active detection device that uses lasers to emit laser pulses or continuous wave laser beams to target, record and analyze echo signals, and obtain information such as distance, azimuth, height, speed, attitude, and shape of the target. Lidar has the advantages of high angular resolution, high distance resolution, wide ranging range, and strong anti-interference ability. It is widely used in the fields of surface topography mapping, atmospheric detection, and 3D virtual reality robot vision. [0003] In recent years, the rapid development of mobile robots has put forward higher requirements for the volume, weight, resolution, and field of view of LiDAR. The existing scanning laser radar transmitting part and receiving part are placed separately, and the space utilization rate is not high, which makes i...
