Abstract :
Recently, because of the blind spot of oversize vehicle, accident happened repeatedly when the vehicle turned right. Therefore, to solve the problem, an embedded system based on computer vision technology which can early warn driver is proposed. Capture image with CCD camera, extract the background by using background subtraction, and build background model by the way of weighted average. After that, obtain all the moving area with MHI(Motion History Image), and sign the areas which are gathered. Then it would warn by judge whether or not the signed area in the warning area.
