Abstract
A method, a system, and a program for high-fidelity three-dimensional modeling of a large-scale urban environment, performing the following steps:
- acquiring imagery of the urban environment, containing vertical aerial stereo-pairs, oblique aerial images; street-level imagery; and terrestrial laser scans,acquiring metadata pertaining to performance, spatial location and orientation of imaging sensors providing the imagery;identifying pixels representing ground control-points and tie-points in every instance of the imagery where the ground control-points and tie-points have been captured;co-registering the instances of the imagery using the ground control-points, the tie-points and the metadata, andreferencing the co-registered imagery to a common, standard coordinate system.
