1. A method for creating a model of a world space, comprising:
back projecting at least one image from at least one camera view to a model of a world space environment;
comparing the at least one back projected image to at least one image from at least one other camera view to determine a set of error metrics by transforming the model of the world space environment to a transformed image for a first camera and comparing the transformed image to an image captured by the first camera; and
aggregating the set of error metrics into a combined differences value and comparing the combined differences value to a threshold value.
