Automatic tracking collision avoidance system and method thereof
First Claim
1. An automatic tracking collision avoidance method, comprising the steps of:
- taking images in front of an origin vehicle by at least two photograph units;
delivering the images to a calculation assembly for transforming the images from images of three primary colors to grey-level images;
obtaining a relative vehicle speed of the front vehicle corresponded to the original vehicle according to the grey-level images; and
enabling the calculation assembly to calculate and obtain a safe distance according to the relative vehicle speed, while making an evaluation to determining whether the safe distance is great than a distance between the original vehicle and the front vehicle, if so, enabling an alarm module to generate an alert signal;
wherein the images are transmitted to a grey-level processing unit where the images are transformed from images of three primary colors into grey-level images, while an alignment unit is enabled to perform a level calibration process and a background light calibration process upon the image of three primary colors, and thereafter, the calibrated images of three primary colors are transmitted back to the grey-level processing unit to be transformed into the grey-level images.

Abstract
An automatic tracking collision avoidance method has following steps: taking images in front of an origin vehicle by at least two photograph units; the images delivering to a calculation assembly, to transform the images from three primary colors images to grey images; having a relative vehicle speed of the front vehicle corresponded to the original vehicle according to the grey images; and according to the grey images the calculation assembly having a relative vehicle speed that the front vehicle corresponded to the original vehicle; the calculation assembly having a safe distance according to the relative vehicle speed, if the safe distance is great than a distance that between the original vehicle and the front vehicle, an alarm module generating an alert signal.

9. An automatic tracking collision avoidance system, comprising:
-
an on-board module; and a calculation assembly, connected to the on-board module for signal transmission, further comprising; an image capturing module, having at least two photograph units; an image processing module, connected to the image capturing module for signal transmission, and further comprising; a grey-level processing unit, connected to the image capturing module for transforming an image of three primary colors that is received from the image capturing module into a grey-level image; an alignment unit, connected to the grey-level processing unit for performing a level calibration process and a background light calibration process upon the image of three primary colors while transmitting the calibrated image of three primary colors to the grey-level processing unit; and an edge detection unit, connected to the grey-level processing unit for detecting and obtaining image edges according to the grey-level image; a calculation module, connected to the on-board module and the image processing module, and further comprising; a depth calculation unit, connected to the edge detection unit for calculating and thus obtaining a depth value and a disparity according to the detected image edges; a tail-light detection unit, connected to the depth calculation unit for calculating and thus obtaining a front-vehicle-tail-light depth value according to the depth value; and a distance conversion unit, connected to the tail-light detection unit for calculating and thus obtaining an actual distance and a vehicle speed according to the front-vehicle-tail-light depth value; and an alarm module, connected to the calculation module for generating an alarm signal in a condition when the actual distance is smaller than a safe distance. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
