Abstract

An image based distance self-calibrating method for automotive electronic system is proposed to ease the difficulty in setup procedure and offset the possible changes caused by moving the camera that used to capture image for distance measurement. By process the information from vertical edge of dashed road line, the lookup table is established to translate the pixel distance to real distance. The only parameter needs to be provided by user is the practical distance that bottom row of captured image stand for. In addition, a noise-insensitive filter is designed to find the edge of dashed road line. As a result, the error is within 1 meter inside the range of 30 meter.
