Abstract

The invention discloses a two-dimensional scanning laser radar device. The two-dimensional scanning laser radar device comprises a transmitting unit, a receiving unit, a control unit connected with the transmitting unit and the receiving unit, a light splitting device and at least three rotating prisms, wherein the transmitting unit comprises at least two lasers and is used for transmitting lasersignals; the light splitting device is used for collimating and / or converging the laser signals and reflecting echo signals reflected by a scanning area; the receiving unit comprises at least two detectors and is used for receiving the echo signals; the rotating prisms are respectively a first rotating prism, a second rotating prism and a third rotating prism and are used for adjusting the scanning direction of the laser signals. According to the two-dimensional scanning laser radar device disclosed by the invention, scanning in multiple angle ranges in the horizontal direction and the vertical direction can be realized through the rotating prisms, the problems that a two-dimensional scanning laser radar is small in scanning range and low in reliability are solved, multi-area scanning canbe realized, the scanning range of the laser radar device is larger, and the distance measuring capability of the laser radar is greatly improved.

Description

technical field [0001] The invention relates to the technical fields of optics and electronics, in particular to a two-dimensional scanning laser radar device and electronic equipment. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. With the advantages of high precision, fast operation speed and high efficiency, it is an indispensable core sensor in the fields of automobile automatic driving, robot positioning and navigation, space environment mapping, security and security. [0003] At present, when the laser radar is working, it mainly transmits the laser signal to the target object through the laser transmitting part installed inside the laser radar, and receives the laser reflection signal reflected by the target object through the laser receiving part set, and records the laser emission and The time point when the laser is received to obtain the time difference b...
