How do I find the distortion coefficients of my camera when it takes aerial shots from about 180 meters? Please help me out here. Is there a relation between distortion coefficients when taken from a lower height to distortion coefficients when image taken from a higher altitude?PrototypeMon, 28 Nov 2016 09:57:48 -0600http://answers.opencv.org/question/115135/What must be the minimum size of the chessboard pattern to obtain most accurate values for distortion co-efficients?http://answers.opencv.org/question/114860/what-must-be-the-minimum-size-of-the-chessboard-pattern-to-obtain-most-accurate-values-for-distortion-co-efficients/ I need to obtain distortion coefficients for an aerial image.I propose to setup a grid pattern on the ground and use it for calibration.How big should the grid pattern be ? Is there any other way to undistort an aerial image?
