Embodiment Construction

[0028]According to the needs of vehicle-mounted obstacle detection, the basic idea of ​​the present invention's forward collision and lane departure warning device based on multi-sensor information fusion is: the vehicle-mounted radar (millimeter wave radar sensor 10) and the front CMOS camera 30 obtain the vehicle road information ahead , and send it to the computer as the on-board processing unit for information fusion processing, detect obstacles in front of the vehicle, and judge its danger level, and finally provide the alarm information to the driver intuitively in the form of a graphical interface, vibration or sound prompts. From the above design ideas, it can be determined that the early warning device of the present invention has the functions of information acquisition, communication, information processing and information output.

[0029] The present invention will be further described in detail below in combination with specific embodiments.

[0030] Such as figu...

Abstract

The invention discloses a multi-sensor information fusion-based forward collision and lane departure pre-warning device, which comprises a millimeter-wave radar, a communication interface module, a video camera, an image acquisition module, a display module, a warning module and a vehicle-mounted processing unit, wherein the vehicle-mounted processing unit can perform fusion processing of radar signals and machine visual information from the communication interface module and the image acquisition module. The pre-warning device is used for warning of forward collision and lane departure of a vehicle, and a pre-warning method comprises the steps of: driving devices; receiving and processing radar data and image data; fusing information; and finally displaying the fused information. According to the multi-sensor information fusion-based forward collision and lane departure pre-warning device disclosed by the invention, potential risk of collision during running of the vehicle can be found through the radar and the video camera so as to provide warning information for a driver. According to the pre-warning method disclosed by the invention, since a method of visible sensation combined with the radar is adopted, the accuracy rate of prevention of collision and lane departure of the vehicle is fundamentally improved, and the degree of accuracy can be increased by 5-20 percent as proved by experiments.

Description

technical field [0001] The invention relates to a safety assistance system for automobile drivers, in particular to an early warning system for avoiding forward collision and lane departure. Background technique [0002] In recent years, with the rapid growth of the number of road vehicles in our country, the situation of road transportation safety has become increasingly severe. Extremely severe and vicious traffic accidents occur frequently, which not only cause many casualties and economic losses, but also easily cause complex social problems. According to the statistics of the Ministry of Public Security in 2007, freight vehicles accounted for 29.4% of the total number of deaths in road traffic accidents in my country. For this reason, the "National Medium and Long-Term Science and Technology Development Plan" (2006-2020) has listed transportation safety technology as a major national scientific and technological demand, and invested a lot of manpower and material resou...
