Abstract

The invention discloses a ranging device combining a solid-state area-array laser radar and two CCD cameras, comprising a solid-state area-array laser radar, a control unit, a calculation unit, and two CCD cameras. The solid-state area-array laser radar and the two CCD cameras are horizontally arranged, and the solid-state area-array laser radar is arranged in the center of the two CCD cameras. The control unit issues a ranging instruction; the solid-state area-array laser radar and the two CCD cameras respectively acquire the distance information and the RGB image information of a target field of view after receiving the ranging instruction; and the calculation unit fuses the distance information and the RGB image information to obtain the ranging result of the solid-state area-array laser radar to each point in the target field of view.

Description

technical field [0001] The invention belongs to the technical field of high-precision area array ranging, and in particular relates to a ranging device combined with a solid-state area array laser radar and double CCD cameras. Background technique [0002] Lidar is a system for measuring distance by emitting and receiving laser light. Its working principle is: the light source driver module drives the light transmitter to send out light signals, and the light signals are reflected and scattered when encountering obstacles during propagation. After the receiver receives the reflected or scattered light signal, the signal processing module compares the emitted light with the received light, and after proper processing, the relative distance from the radar to the obstacle is obtained. [0003] Two CCD cameras are a system for measuring distance through binocular vision algorithms. Determine the distance of feature points in the image or all points in the image. [0004] For a...
