Drive Line Segment Fitting Algorithm Based on Dynamic Region of Interest
Lin Wei · Modern Computer · 2011
Proposes drive line detection algorithm based on dynamic region of interest and fitting algorithm.Dynamically adjusts of region of interest(ROI) and reduces the processing space.Using Otsu algorithm(OTSU) dynamically extracts gray level threshold,and makes it as the gray level threshold of the multi-direction Sobel gradient edge detection to improve the accuracy,uses Zhang-Suen skeleton the edge images,then removes burrs and divides the image into two regions.In different regions and conditions,uses line or curve fitting to improve precision.Simulation result shows that a frame with simple background,the processing time is about 15ms,while with complex background,is about 35ms,it can meet the real-time requirements.
