Abstract
A method of imaging a scene includes estimating multiple three-dimensional (3D) representations, each of which corresponds to a respective portion of the scene. Neighboring portions of the scene area are at least partially overlapping. Each 3D representation is estimated by illuminating the respective portion of the scene with a light burst including multiple light pulses, after which multiple point clouds are generated by detecting photons reflected or scattered from the respective portion of the scene using a focal plane array. Data points in the point clouds represent a distance between the focal plane array and a scene point in the respective portion of the scene. The 3D representation is then estimated based on the multiple point clouds via coincidence processing. The method then generates a 3D image of the scene based on the multiple 3D representations.
