METHOD AND SYSTEM FOR GROUND TRUTH DETERMINATION IN LANE DEPARTURE WARNING

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for ground truth determination in lane departure warnings.SOLUTION: The methods include receiving a plurality of time slice images of a lane captured at a plurality of different time frames from an image capturing unit. The intensity profiles of these time slice images are determined and these intensity profiles of the plurality of images are smoothened to obtain a smoothened histogram. A threshold value of these time slice images are determined and further refined to extract the lane marking of a lane. A ground truth value is detected that is used for validating a lane departure warning.SELECTED DRAWING: Figure 3
