Abstract:
A traffic monitoring apparatus for detecting an abnormality in traffic by monitoring images produced by an imaging device, the apparatus comprising:image inputting means for inputting images produced by the imaging device; move vector extracting means for extracting a move vector of an object from images input from the image inputting means; parameter calculating means for calculating parameters in the case of a move vector extracted by the move vector extracting means being considered as a segment; plotting means for plotting parameters for a segment calculated by the parameter calculating means in a two-dimensional coordinate system with the parameters as its bases; and abnormality judging means for judging, in the case of the parameters for a segment plotted in an unusual area, that an abnormality has occurred, wherein the parameter calculating means calculates the slope and intercept, being parameters, of a segment by performing Hough transformation on the move vector.
