Accurate 3D Mapping Algorithm for Flexible Antennas

Figure 10

An example of the flowchart of the dish edge detection process. (a) The acquired image is binarized. (b) The intersections between the ribs of the dish with the dish are “cleaned.” (c) Detecting the connected components in the binarized image is exemplified. (d) The edge of the dish is then located by finding the resultant convex hull.
