Abstract

A multi-line Lidar is provided. The multi-line Lidar includes: a multi-line ranging laser emission module comprising one or more lasers; a multi-line ranging laser reception module comprising one or more photodetectors and adapted to detect a laser echo generated when a measurement laser emitted by the laser emission module is incident to an obstacle and is diffusedly reflected; a ranging information resolution module in electrical signal connection with the multi-line ranging laser emission module and the multi-line ranging laser reception module, and designed to calculate the distance, in each direction, to the obstacle by means of calculating the time difference between the emission of the measurement laser and the receiving of the laser echo; and a control circuit and an optical system correspondingly configured for the multi-line ranging laser emission module and the multi-line ranging laser reception module.
