Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same components are denoted by the same reference numerals.

[0023] refer to figure 1 As shown, an unmanned driving system based on a single-line laser radar and a millimeter-wave radar in this embodiment includes a camera module 1, a millimeter-wave radar 2, a control module 3, a driving module 4, and a single-line laser radar 5 arranged on the vehicle. , cloud communication module 6, positioning module 7, roadside unit 8 and voice prompt module 9;

[0024] The camera module 1 is used to take pictures of the front of the vehicle and generate picture data, and send the picture data to the control module 3 in real time. The camera module 1 faces directly ahead of the vehicle. The camera module 1 is a vehicle-mounted monocular camera. The cost of the monocular camera is low, but the distance measurement effect is not good. The dist...

Abstract

The invention discloses an unmanned driving system based on a single-line laser radar and a millimeter-wave radar. The unmanned driving system is characterized by comprising a camera module, the millimeter-wave radar, a control module, a driving module and the single-line laser radar, the camera shooting module is used for shooting the front of the vehicle, generating camera shooting data and sending the camera shooting data to the control module in real time; the millimeter-wave radar is used for detecting the front of a vehicle and generating millimeter-wave data, performing Doppler still life elimination on the millimeter-wave data and then generating filtering data and sending the filtering data to the control module; the single-line laser radar is used for detecting the front of a vehicle, generating single-line laser data and sending the single-line laser data to the control module. And the control module generates first road information and second road information, and controls the driving module to perform driving operation according to the first road information and the second road information. The system can improve the judgment reliability of front still objects, especially static special-shaped trucks, and is low in cost.

Description

technical field [0001] The present invention relates to the field of unmanned driving, and more specifically relates to an unmanned driving system based on single-line laser radar and millimeter wave radar. Background technique [0002] In recent years, cars equipped with assisted driving functions have sprung up like mushrooms after the spring rain. For the realization of adaptive cruise control functions, different car manufacturers have adopted different solutions. Specifically, it can be realized through vision, also through millimeter-wave radar, and through multi-line lidar. Among them, the scheme of vision and millimeter-wave radar is currently the more commonly used scheme. Its advantage is that the cost is relatively good, and the disadvantage is that it is difficult to identify the still objects in front and cannot recognize stationary special-shaped vehicles such as special-shaped trucks, and the judgment reliability is not high. The main reason is that millimeter...
