Sequence Annular Image Processing Technology and Its Application
Chengliang Wang · Jisuanji gongcheng · 2009
Combining the particular application in geological exploration,by the control of depth,the sequence of images,reflected from the space of entire section(360o) of the borehole wall,is presented as annuals images on the screen.The overlapping part between the two sequence images are chosen based on the theory of image stitching error.A new seed filling method based on link queue is used to find the center and radius of the circle.By traversing every concentric circle according to a given angle,the annular images are expanded into rectangle.Using the overlapped information between two sequence images and grid matching method,it makes the sequence images stitch smoothly which are more convenient for observation.
