Velocity restraint-based Hough transformation fast track starting method



The invention provides a velocity restraint-based new Hough transformation fast track starting method under dense cluttered environment. The method comprises the following steps: performing combination pairing and velocity restraint on data measured by a sensor in all scanning periods, deleting a part of pairs formed by clutter, resolving the accurate intersection points of pairs in a parameter space by utilizing a Hough transformation formula, extracting public intersection points through the segmentation and threshold setting of the parameter space, to obtain a candidate track, and screening the following track by utilizing the speed restraint, to obtain a final confirmation track. According to the method, the false track formed by the clutter can be effectively inhibited, the fast starting of the track can be guaranteed, and better robustness on the clutter interference can be achieved.
