Application background Simple image processing, hoping to be the center point on the calibration panel to find out as expected, into the gray scale image wave through the low pass rate and history of image, the filtered image noise, to find the exact dot centroid!!! hope all guys can try it ! Key Technology The technique discussed will allow for full calibration and correction of
x,y pixel coordinates while only taking two uncalibrated and one calibrated measurement. These are done
by finding the observed x,y coordinates of a calibration target. Any Fisheye lens that has a roughly
spherical shape can have its distortion corrected with this technique. Two measurements are taken to
discover the edges and centroid of the lens. These can be done automatically by the computer and does not
require any knowledge about the lens or the location of the calibration target. A third measurement is then
