    摘要: In general, the invention includes a method and system of rectangular solid detection comprising: receiving an image of data; detecting edges from the image of data; finding lines from the image of data; finding junctions from the lines; filtering junctions and lines that meet a first set of certain criteria; grouping the junctions and lines that meet a second set of certain criteria; and detecting whether a rectangular solid exists in the image according to the grouping. The criteria includes using triplets of lines and fork junctions. The system and method may also analyze a single frame, or a single frame paired with a reference frame.
