Embodiment Construction

[0019] The content of the present invention will be further described below in conjunction with the accompanying drawings, but the actual method of the present invention is not limited to the following embodiments. 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.

[0020] A method for early warning of lane change depth for a driver in a high-speed driving environment, comprising the following steps:

[0021] One, such as figure 2 As shown, install the camera. The camera 2 is installed on the lower edge of the rearview mirror 1, the direction of the optical axis of the camera is toward the rear of the vehicle, and the angle between the camera and the longitudinal centerline of the vehicle body is 3°. A camera is respectively installed in the left and right rearview mirrors, and the installation is as follows: figur...

Abstract

The invention discloses a method for early warning of the driver's lane change depth in a high-speed driving environment. A camera is used to collect the side and rear images of the vehicle, and the collected side and rear images of the vehicle are transmitted to the computer. The deep learning network of road depth warning completes the end-to-end mapping between the camera’s image input of the vehicle on the side and rear of the highway and the output vehicle type, and uses the network to simultaneously complete the vehicle type identification and mark the identification frame, and recognize the output vehicle The type of image is used to measure the distance, and then the vehicle ECU is used to determine the operating status of the vehicle. If the detection range of 0-100m recognizes the vehicle type, the driver will be given an early warning to achieve the safety of the driver's lane change depth warning in the high-speed driving environment. The invention reduces the error rate of identification, improves the accuracy of identification and realizes real-time monitoring. Realize real-time automatic identification, distance calculation, and early warning of vehicle models in the area behind the vehicle.

Description

technical field [0001] The invention belongs to the field of automobile safety, and relates to a driver lane change depth early warning safety system for high-speed driving environment. Background technique [0002] To reduce the losses caused by traffic accidents has become a problem that people pay more and more attention to. As an effective means of reducing traffic accidents and accident losses, automobile safety assisted driving technology has been favored by governments of various countries. Automobile safety assisted driving technology has become a research hotspot for scholars and automobile companies in various countries. Some people have proposed such as: ARM-based vehicle lane change video detection system, vehicle lane change monitoring system based on vehicle millimeter wave, etc. But the traditional system is mainly based on eliminating the driver's visual blind spot in the high-speed driving environment. It has mainly gone through the following four stages o...
