Problems solved by technology

Most of these studies are carried out on ideal external environments, and there are few studies on the recognition of lane markings under harsh lighting conditions. At present, there is no method that can accurately extract the parameters of lane markings under different lighting conditions.
In addition, there is a lack of in-depth and systematic research on the lane departure warning system

Embodiment Construction

[0034] The hardware installation of the present invention requires the smart camera to be installed horizontally, with the lens facing forward, that is, the direction of its optical axis is parallel to the ground. At the same time, the installation position of the smart camera is as close as possible to the middle position in the transverse direction of the front windshield. The installation height H depends on different types of vehicles.

[0035]When the vehicle is running on a high-grade highway, the lane departure warning function can be realized by pressing the start button on the front panel of the electronic control device. First, the image information collection module a timely collects images of the scene in front of the vehicle, and the images can contain road surface information in front of the vehicle within the field of vision. When the image information acquisition module acquires a frame of image, start the lane marking line recognition and tracking module b mo...

Abstract

The invention relates to a vehicle bias alarm method and relative system, for alarming driver to avoid bias and accidence. The output of inverter power and one end of relay is connected with an output signal interface of an intelligent camera, the picture information collecting module, channel mark line recognizing module, vehicle direction parameter evaluation module, vehicle position parameter evaluation module, channel width evaluation module and channel bias alarm module are embedded in the chip of the camera, while the intelligent camera via a mounting support is fixed in the front windscreen glass of cabin, and said six modules should started in serially to realize the alarm method.

Description

technical field [0001] The invention relates to the field of intelligent transportation and intelligent vehicle research, in particular to a method and a system for detecting the running state of a vehicle in a lane, and sending a warning to the driver when the vehicle is detected to deviate from the lane. Background technique [0002] Vision-based lane departure warning systems mostly rely on lane markings or road boundary information on the road. How to quickly and accurately extract the lane marking information on the road is the key problem that this type of system must solve. During the research process of autonomous navigation of intelligent vehicles in our country, some researches have been carried out on the recognition and tracking methods of lane markings based on vision, and some research results have been obtained. Most of these studies are carried out for ideal external environments, and there are few studies on the recognition of lane markings under harsh ligh...
