Method of compensating for noise in lane drifting warning system |
摘要 |
A method of compensating for noise in a lane drifting warning system for vehicles. The method includes the steps of converting input image signals into binary data; determining if the converted image signals are those from a start of a lane detecting process; reading previously stored data of the slant in the lane markers if it is determined that it is not the start of the lane detecting process; compensating for peripheral environment noise in the slant in the lane markers; extracting portions of the signals determined to be possible indications of road lane markers if it is determined that it is the start of the lane detecting process; extracting actual lane marker portions from the portions of the signals determined to be possible indications of road lane markers; measuring and storing a slant in the lane markers; calculating a width of a lane defined by the lane markers and determining if the vehicle is veering from the lane; and outputting a warning to alert the driver if the vehicle is veering from the lane. <IMAGE> |
