Abstract

The invention provides a multi-beam laser ranging sensor based on TOF. The multi-beam laser ranging sensor based on the TOF comprises a digital processing unit, a laser emission unit, an optical system unit and a laser receiving unit; the laser emission unit is used for emitting at least three lasers according to a laser emission signal sent by the digital processing unit; the optical system unitis used for focusing the lasers to a measured object, and the lasers reflected by the measured object are reflected to the laser receiving unit; the laser receiving unit is used for generating a laserreceiving signal based on the received lasers and sending the laser receiving signal to the digital processing unit; and the digital processing unit is used for obtaining the distance from the corresponding laser to the measured object based on the laser emission signal and the laser receiving signal. According to the multi-beam laser ranging sensor based on the TOF, the problems that existing laser measuring frequency and resolution ratio are low, an object outline is not clear and the detection view is narrow are solved through multi-beam laser ranging.

Description

technical field [0001] The present invention relates to the technical field of laser ranging sensors, in particular to a multi-beam laser ranging sensor based on Time of Flight (Time of Flight, TOF). Background technique [0002] TOF technology means that the sensor emits modulated near-infrared light and reflects it when it encounters an object. The sensor calculates the time difference or phase difference between light emission and reflection, and converts the distance of the object according to the time difference or phase difference to generate depth information. In addition, combined with the object The reflected echo energy intensity, combined with the measurement distance, can present the three-dimensional outline of the object in the form of topographic maps with different colors representing different distances. [0003] In the prior art, most TOF-based laser ranging sensors use single-beam laser emission as the measurement core. Among them, the single-beam laser r...
