Abstract

The invention provides a laser radar and a ranging method for realizing scanning field of view partitions, the laser radar includes: a transmitting system, a receiving system, and a control and signal processing unit, and the transmitting system includes a first laser light source and a second laser A light source, the first laser light source is used to emit a first laser beam, and the second laser light source is used to emit a second laser beam; the first laser beam is used to scan the first area of ​​the space to be measured, and the second laser beam is used to It is used to scan the second area of ​​the space to be measured; the receiving system includes a first detector and a second detector, the first detector is used to receive the first echo signal returned by the first laser beam, and the second detector is used to receive the second laser beam The second echo signal returned by the beam. The invention can realize the detection of different areas by the same laser radar.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a laser radar and a ranging method for realizing scanning field of view partitions. Background technique [0002] Lidar can obtain the three-dimensional spatial information of the area to be measured by actively emitting laser beams to the area to be measured and detecting the echo signals reflected back from the space to be measured. Due to the high ranging accuracy and fast response speed of lidar, it can obtain enough rich three-dimensional space information, so it has a wide range of applications in various directions such as machine vision, assisted driving, and indoor scene scanning and reconstruction. [0003] However, the existing lidar products can only detect a certain area. When multiple areas need to be detected at the same time, multiple lidars are often required to be used together to meet the application requirements. Contents of the invention [0004] Aimin...
