Claim One:
1. A method for multi-resolution hierarchical radiance field estimation of an enclosure, comprising: dividing an enclosure into a number of first field elements of a first resolution and a number of second field elements of a second resolution; determining radiance of a number of first imaging elements of a first resolution and radiance of a number of second imaging elements of a second resolution using images of the enclosure; estimating a radiance field and converged parameters of the number of first field elements of the enclosure using initialized parameters of the number of first field elements and the determined radiance of the number of first imaging elements; and estimating a radiance field and converged parameters of the number of second field elements of an enclosure using converged parameters of the number of first field elements, the estimated radiance of the number of first field elements, and the determined radiance of the number of second imaging elements.
