Abstract

The invention relates to a laser radar system and a detection method. In the laser radar system, a transmitting module comprises at least one transmitting unit used for transmitting emergent laser. The detection module at least comprises a first detection unit and a second detection unit. The first detection unit is used for receiving echo laser returned by an object in a first field angle after reflection; and the second detection unit is used for receiving echo laser returned after the object in the second field angle is reflected, and the distance measurement range in the second field angleis greater than the distance measurement range in the first field angle, so that reasonable division of the whole field of view of the detection area can be realized. Therefore, the laser radar system can improve the range finding range in the second field angle while guaranteeing the range finding range in the first field angle, thereby improving the overall detection performance of the laser radar system. And the processing module is used for processing the echo laser received by the detection module so as to realize detection of a target in a detection area.

Description

technical field [0001] The present application relates to the technical field of laser radar, in particular to a laser radar system and detection method. Background technique [0002] The transmitting end of the solid-state flash lidar emits an area array laser, and the area array laser is incident on the detection target and scattered by the detection target, and its receiving end records the pixel points to record the photon time-of-flight information. Therefore, solid-state flash lidar can be applied to near-field blindness compensation, obstacle avoidance and early warning of vehicles in the field of autonomous driving. [0003] However, solid-state flash lidar is difficult to achieve long-distance detection due to its transmission and reception characteristics. However, the detection requirements in practical applications are not uniform, and both far-field and near-field detection are often required. Contents of the invention [0004] Based on this, it is necessary...
