Application of probabilistic Hough transform in detecting coal level of coal bin
Sun Ji-ping, Bing Wu · Meitan xuebao · 2004
Using computer vision technique to detect coal level of coal bin,a new Hough transform algorithm was developed for finding-circle.It employs gradient orientation to define potential circles using point-pairs.It samples F~(2)instead of F~(3),and transforms the sampled pairs into very small sets of parameter vectors in Q.The result is high speed,increased accuracy and very low memory resources.Using the algorithm to detect coal level of coal bin,the result is satisfy.
