Abstract
A method determines poses of a sensors distributed in an environment. A signal of the environment is acquired by each sensor. Features in each signal that correspond to the features in at least one other signal are identified. Directions between the sensors and the corresponding features are determined. Nullspaces of the directions are used to construct a matrix. A nullspace eigenvector is determined of the matrix, and then the nullspace eigenvector is reconfigured to a matrix specifying the locations of the sensors.
