Abstract
A vehicular collision warning system comprises at least one image capture device capturing images of blind spots, a processing unit receiving the images of blind spots from the image capture device, and at least one alert device. The processing unit identifies at least one barrier from the images and calculates the speed and transverse displacement of the barrier according to the positional change with respect to time. The processing unit presets at least one attention area on the image, estimates whether the barrier will appear in the attention area, sends out an alert-triggering signal to trigger the alert devices to generate sound, light, or pictures to warn the driver early. Cooperating with the speed sensor, brake system and turn light system, the vehicular collision warning system can trigger different alert signals according to the grading of danger to actively warn the driver early.
