Abstract
A dynamic depth extraction method (DDEM) is proposed, which tracks the time taken for a detected edge to move a known distance on the image plane and hence is able to calculate depth. Experimental results for three vertical bars of differing depth show the mean depths obtained were almost the same as those obtained from direct measurement. The fluctuation of obtained depth was about 3.6%, which corresponds to one half frame difference in matching time of the near bar. The DDEM was also successfully applied to a complicated room
