Class Zhang99OptimizationJacobian

java.lang.Object

boofcv.alg.geo.calibration.Zhang99OptimizationJacobian

All Implemented Interfaces:

org.ddogleg.optimization.functions.FunctionNtoMxN

public class Zhang99OptimizationJacobian
extends java.lang.Object
implements org.ddogleg.optimization.functions.FunctionNtoMxN

Analytical Jacobian for optimizing calibration parameters.

NOTE: Accuracy is tested in a unit test using a numerical Jacobian. A very crude tolerance was required to make it pass. I think this implementation is correct, but hand computing the Jacobian is error prone. In practice it produces virtually the same final results as the numerical Jacobian.
