1. A method for residual error mitigation, comprising:
capturing one or more images viewing an object of known dimensions;
computing the object dimensions using a current set of calibration parameters;
computing an error in the computed dimensions by comparing the computed dimensions to the known dimensions;
determining whether the error has been minimized;
if it is determined that the error has not been minimized, adjusting the calibration parameters; and
returning to the step of computing the dimensions of the object using the adjusted current set of calibration parameters.
