Problems solved by technology

[0002] At present, in the research on vehicle anti-rear collision warning technology, one method is to use detection radar installed at the rear of the vehicle to determine whether there is a vehicle approaching from behind. This method is a passive warning and cannot well avoid the possibility of being rear-end collision.
If the car stops on the ro...

Embodiment Construction

[0059] The installation of the smart camera 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 (the height of the optical axis of the smart camera from the ground) depends on different types of vehicles.

[0060] When the vehicle is running on a high-grade highway, the anti-rear collision warning function of the vehicle can be realized by pressing the start button 6 . At this time, the smart camera 9 and its built-in information processing part III start to work, and its specific work flow is shown in FIG. 2 .

[0061] First, the image information acquisition module a timely collects images of the scene in front of the vehicle, and the images can contain informat...

Abstract

The invention relates to a vehicle anti-impact alarm method and relative system, for alarming driver to avoid impact 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, vehicle character extracting module, information analyzing module, vehicle position tracking module, ranging speed measuring module and anti-impact 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, specifically a system for predicting whether a rear-end collision between the vehicle and the vehicle in front can occur, and sending a warning to the driver when there is a possibility of a rear-end collision. Background technique [0002] At present, in the research on vehicle anti-rear collision warning technology, one method is to use detection radar installed at the rear of the vehicle to determine whether there is a vehicle approaching from behind. This method is a passive warning and cannot well avoid the possibility of being rear-end collision. . If the car stops on the road due to an accident, although the anti-rear collision warning system can issue a warning, the car cannot be manipulated to avoid the vehicle hitting from behind. The other is to install a detection radar at the front of the vehicle. Although this method is an active warning, s...
