System and method for image registration and camera calibration using learned error functions

A non-transitory computer readable medium comprising computer executable instructions for registering input images to reference objects to generate output parameters, comprising instructions for:

• obtaining an input image from an imaging device;
• obtaining a reference object, wherein the reference object comprises a reference image or a template corresponding to a model of content in the reference image;
• performing a registration of the input image by estimating a geometric transform and/or a set of non-linear transform parameters, without using predefined image features;
• measuring a misalignment error between the input images and the reference object;
• and
• generating a set of output parameters characterizing the registration as the geometric transform and/or the set of non-linear transform parameters, wherein the geometric transform is associated with intrinsic and extrinsic parameters of the imaging device, and the set of non-linear transform parameters are associated with optical distortion parameters of the imaging device for performing imaging device calibration.
