Abstract

A Dual-Core DSP Based lane departure warning system (LDWS) with a high dynamic range (HDR) CMOS camera is presented in this paper. We developed the HDR camera with the image sensor MT9V022, which has specifically been designed to support automotive imaging needs. Image data is transmitted across the vehicle as serial LVDS (low voltage differential signal) data, with reduced emissions and drastically improved immunity to external interference. The DSP image processor on LDWS works with operating frequency of 600MHz and the lane marking detection speed can be more than 25 frames per second. The presented fast adaptive lane detection algorithm is efficient and robust. And the Time to Lane Cross (TLC) criterion is used to determine when the vehicle is in danger of departing lane. The LDWS is equipped on the test vehicle and has been successfully verified for hundreds of kilometers on highway.
