Adaptive lane departure warning system on Android smartphone

This study proposes an adaptive Lane Departure Warning system (LDW) on smartphone, to deal with flexible warning capability for different road environment and driver behavior. The proposed system is migrated the preliminary developed LDW algorithm and utilizing mobile camera built-in Android smartphone to capture images of road environment. Through "Java Call C" approach, the LDW kernel is processing the captured images to obtain line-marking of road. When the vehicle departs from its lane, the departure alarm is active. An adaptive mechanism could adjust the parameters of alarm box according to different driving situations without any extra manual setting and yields user-friendly manipulation.
