Abstract: A traffic sign identification method using a traffic sign identification system includes: operating a traffic sign image capture unit to capture a road condition image, operating a traffic sign image recognition unit to pick up a traffic sign image from the road condition image, and operating an arithmetic processing unit to convert the original RGB color space of the traffic sign image into a HIS color space, and then to extract one or multiple graphical features from the HIS color space subject to a predetermined graphic pattern, and then to execute a positioning procedure to allocate one traffic sign in the traffic sign image so as to further obtain a digital speed limit image using a matching arithmetic, and then to convert digital speed limit image into a digital speed limit skeleton diagram for identification of the speed limit value of the traffic sign image.

Abstract: A driving condition identification system mounted in a car, including an image capture unit adapted for capturing images of the scene in front of the car to produce a continuous video signal when the car stands still, and an operation processing unit electrically coupled with the image capture unit and adapted for receiving and processing the continuous video signal to determine images of an object in the continuous video signal in front of the car, to analyze changes in the images of the object in front of said car, and to determine the object in front of the car to be in movement or not.
