Strip plots for intrinsic parameters expressed as fractional error (standard deviation divided by value) and the RMS reprojection error, expressed as a fraction of the image width (error in pixels divided by image width in pixels). Errors are normalised here to facilitate comparisons between cameras with very different focal lengths and image sizes. Chessboard calibration consistently gives lower errors in parameter estimates and reprojection error compared to vicarious techniques (stars and terrain)
