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.

Abstract: The present invention discloses a fast object position detection device and a method thereof, particularly to a detection device and a method thereof which can directly apply to various image systems. The device of the present invention mainly comprises an image capturing system that captures images within the regions defined by the user, and an image processing unit determining the position of an object and obtaining related information. In the method of the present invention, a captured image is converted into 1-D distance-axis signal information; a differential value of the 1-D distance-axis signal information is used to determine a position of an object; and a difference of the 1-D distance-axis signal information of at least two adjacent time points is used to determine an approaching status of an object.
