Embodiment Construction

[0046] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0047] An aspect of the embodiments of the present invention provides a false positive detection method for forward collision warning, wherein, as figure 1 As shown, the forward collision warning methods include:

[0048] Image capture step: the camera captures and transmits the image signal of the vehicle in front;

[0049] The step of identifying the position of the vehicle in front: setting an effective area for detecting the position of the vehicle in front, obtaining the horizontal and vertical edges of the image signal in the effective area, and determining the position information of the vehicle in front;

[0050] Collision detection step: Obtain the distance and vehicle speed between the ...

Abstract

The present invention provides a false alarm detection method and device for a forward collision alarm, comprising: an image capture step, a front vehicle position recognition step, a collision detection step, and an alarm step; further comprising: after the image capture step, performing: collecting the front vehicle Image signal forms video data; playback video data; forward collision alarm processing steps: input video data to carry out front vehicle position recognition steps, collision detection steps, and obtain forward collision alarm information; false alarm rate statistics step: calibrate forward collision auxiliary judgment line, when the video data playback process, the position of the vehicle in front crosses the forward collision auxiliary judgment line, it is judged as a forward collision case; compare the forward collision case with the forward collision warning information, and count the forward collision warning misreporting rate. The invention achieves the technical effect of reducing the complexity of the false report detection of the forward collision warning system and making the false report detection of the forward collision warning system repeatable and reproducible.

Description

technical field [0001] The invention relates to the technical field of performance testing of a forward collision warning system, in particular to a method and device for detecting false positives of a lane forward collision warning. Background technique [0002] Forward Collision Warning (ForwardColisionWarning, referred to as: FCW) system is one of Advanced Driver Assistance Systems (Advanced Driver Assistance Systems, referred to as: ADAS), is a car driving safety assistance system. When the sensing element detects that the distance to the vehicle in front is too close, if the driver fails to brake due to fatigue or negligence, the system will send out a warning signal to remind the driver to brake. The Forward Collision Warning (FCW) system currently uses the camera as the main sensor, detects and tracks the position of the vehicle ahead based on machine vision technology, and judges whether the vehicle is in danger of collision based on the characteristics of the driver...
