Abstract: PURPOSE: A device for detecting a vehicle and calculating the distance between the vehicles using stereo vision are provided to recognize the vehicle with a simple method about a vehicle nominating area detected from the image by determining availability in Canny Edge image extracted by vehicle detection technology based on a computer. CONSTITUTION: A device for detecting a vehicle and calculating the distance between the vehicles using stereo vision comprises a stereo vision unit(100), a pre-processor(110), and a unit(120) for detecting the vehicle and calculating the distance between the vehicles. The stereo vision unit detects the left image and the distance image corrected from an image signal. The image signal is filmed by right and left cameras installed in the vehicle. The pre-processor extracts edge information based on an output signal of the stereo vision unit. The unit for detecting the vehicle and calculating the distance between the vehicles detects a corner of the vehicle based on the edge information. The unit detects the vehicle and calculates the distance between the vehicles from image information through expanding a vehicle area, grouping, and testing availability.

Abstract: PURPOSE: An image processing device and a method for comparing an object shape in real-time are provided to reduce the error in shape comparison depending on the size and arrangement angle of an object by judging the shape similarity. CONSTITUTION: A binary image generator(120) generates binary image data, and a subject connection component detector(130) analyzes the binary image data. The subject connection component detector displays the pixel value of an image in arrangement. A subject property decision unit(140) detects the characteristic information depending on the size and angle. A subject shape acquisition unit converts the component value arrangement. The component value arrange is mapped to an object window. The subject shape comparison unit(180) compares the component value arrangement with the reference component arrangement.
