Problems solved by technology
When following vehicles, the smart car can use the automatic emergency braking technology in the on-board driving assistance device to avoid rear-end collision of the vehicle in front, but when the smart car is rear-ended by the rear vehicle, it cannot actively avoid danger
Or when the self-driving vehicle is waiting for a traffic light at an intersection, the stopping posture of the self-driving car is not correct, or the parking position is the lane waiting to turn, and the vehicle body is parked at a certain angle. Parking at an angle, causing rear collision warning false alarm

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

The invention relates to the technical field of intelligent vehicle automatic driving, and discloses a collision early warning system based on fusion of a foresight camera and a rear millimeter wave radar, and the system comprises a visual detection module which is used for shooting and processing a road condition image in front of an intelligent vehicle, and obtaining the front road condition information; the rear millimeter wave radar is used for acquiring rear obstacle information of the intelligent vehicle by a user, and the rear obstacle information comprises obstacle speed; the data processing module is used for processing the road condition information and the rear obstacle information and comprises a rear early warning processing unit, and the rear early warning processing unit is used for obtaining collision time according to the relative speed of the rear obstacle and the intelligent vehicle in the y direction and giving an alarm when the collision time reaches a rear collision threshold value. According to the scheme, safe driving of the intelligent vehicle is guaranteed through the front-back early warning function, the probability of collision of the vehicle is greatly reduced, and the driving safety of the intelligent vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of intelligent vehicle automatic driving, in particular to a collision warning system based on fusion of a front-view camera and a rear millimeter-wave radar. Background technique [0002] In recent years, artificial intelligence technology has been widely used in the automobile industry, and automobiles are also constantly developing in the direction of intelligence. Many vehicles are equipped with certain driving assistance devices and intelligent devices to assist drivers to perceive and control, which can further improve the safety of driving. When following vehicles, the smart car can use the automatic emergency braking technology in the on-board driving assistance device to avoid rear-end collision of the vehicle in front, but when the smart car is rear-ended by the rear vehicle, it cannot actively avoid danger. Or when the self-driving vehicle is waiting for a traffic light at an intersection, the st...
