Abstract:
1. A method for reconstructing an unidentified boundary of a traffic lane including a left boundary and right boundary, comprising the steps of: capturing a plurality of traffic lane images by a front imaging unit; providing a top boundary predicting relationship curve and a bottom boundary predicting relationship curve by a control unit, wherein the top boundary predicting relationship curve defines a top geometric relationship between the left boundary and the right boundary at top of a region of interest (ROI) in a traffic lane image, and the bottom boundary predicting relationship curve defines a bottom geometric relationship between the left boundary and the right boundary at bottom of the ROI in the traffic lane image, and the top boundary predicting relationship curve and the bottom boundary predicting relationship curve are determined by a determining process comprising the steps of: reconstructing the unidentifiable boundary in any traffic lane image by applying the measured first and second set of characteristic values into the top boundary predicting relationship curve and the bottom boundary predicting relationship curve, by the control unit; dynamically updating the top boundary predicting relationship curve and the bottom boundary predicting relationship curve when width of the lane is changed by repeating the determining process to update the top boundary predicting relationship curve and the bottom boundary predicting relationship curve; detecting a vehicle status by a vehicle status detecting unit, and forwarding the vehicle status to control unit; issuing an alarm signal by the control unit as the control unit evaluates the vehicle status and determine a precaution is needed; and generating an alarm by an alerting unit, wherein the alerting unit is coupled to the control unit for receiving the alarm signal to generate the alarm.
