Abstract

The present invention relates to a laser radar (100) and an automatic driving apparatus. The laser radar comprises an emission driving system (1), an emission system (2), a receiving system (3) and a signal processing system (4). The emitting system (2) comprises a plurality of light emitting units (21a) for emitting emergent laser, and the emitting system (2) is used for starting the light emitting units (21a) according to a first sequence to enable the emergent laser to traverse a detection area in a scanning manner; the receiving system (3) comprises a plurality of detection units (31a) used for receiving the echo laser, and the receiving system (3) is used for starting the selected detection units (31a) to receive the echo laser and detect a detection area scanned by the emergent laser emitted by the light emitting units (21a); the launching driving system (1) is used for driving the launching system (2); the signal processing system (4) is used for calculating the distance information of an object in the detection area based on the emergent laser and the echo laser; the detection unit (31a) comprises a photosensitive area, the ratio of the area of the photosensitive area to the pixel area of the detection unit (31a) is smaller than or equal to 0.5, and the ability of the laser radar (100) to resist ambient light is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radar, and in particular, to a laser radar and an automatic driving device. Background technique [0002] Lidar is a radar system that uses laser light to detect the position, speed and other characteristics of the target object. Its working principle is that the transmitting system first emits the outgoing laser for detection to the target, and then the receiving system receives the echo laser reflected from the target object. After processing the received echo laser, the relevant information of the target object can be obtained, such as distance, azimuth, height, speed, attitude, and even shape and other parameters. [0003] Area array laser radar refers to the laser radar in which both the transmitting system and the receiving system are area arrays, and there is no rotating scanning structure. For example, the transmitting system is a vertical cavity surface emitting laser array...
