Problems solved by technology

Light changes lead to large image deviations, which will lead to matching failures or low accuracy, and it is difficult to work in nighttime environments
[0009] 2) It is not suitable for scenes that are monotonous and lack texture
Binocular vision performs image matching based on visual features, and no features will cause matching failure

Abstract

The invention discloses a structural line laser and inclined binocular combined vehicle-mounted visual radar system which comprises a shell and a support rod fixed in the shell, two aluminum alloy camera bases are fixed on the support rod, and camera modules are respectively arranged on the two aluminum alloy camera bases; an arc-shaped laser device support is further installed between the two aluminum alloy camera bases on the supporting rod, a plurality of infrared laser devices and diffractive optical lenses are annularly distributed on the arc-shaped laser device support at equal angles, and the diffractive optical lenses are located on the outer sides of the transmitting ends of the infrared laser devices and correspond to the infrared laser devices in a one-to-one mode. Structural line laser and the binocular camera are adopted to realize the capability similar to that of a multi-line scanning laser radar, and the system has huge price advantage compared with the laser radar. Meanwhile, the camera is used as a laser information receiving end, so that the vehicle-mounted visual radar system combining the structural line laser and the inclined binocular does not have the common crosstalk problem of the laser radar, and can be intensively applied on a large scale.

Description

technical field [0001] The invention relates to the field of vehicle-mounted electronics, and particularly designs a vehicle-mounted vision radar system combining structural line laser and tilted binoculars. Background technique [0002] In the field of ADAS and autonomous driving, there are mainly four sensors in the forward-facing system of the car, including millimeter-wave radar, lidar, monocular camera, and binocular camera. [0003] LiDAR is a sensor used to accurately obtain the position, size, speed, and external contour of the measured object. LiDAR (Light Detection and Ranging): It is the abbreviation of laser detection and ranging system. Its working principle is to calculate the straight-line distance between the laser scanner and the target by measuring the flight time of the laser with the laser ranging device. The basic optoelectronic components in lidar are semiconductor lasers and APDs. [0004] The interference (crosstalk) problem of lidar, what really i...
