Practical application of the geo-bridging method using linear object segments
It is known that the linear object segments can be used for the geo-bridging of the bush-broom images. Road guard lines, fences, navigation tracks, horizontal lines, walls basis and concrete blocks, etc. are used as linear objects. The application of the vertical lines of the building’s corners as a linear object for geo-bridging of the bush-broom images and determination of the heights of buildings will be describe in this article. Practical examples of using structures for geo-bridging of bush-broom images and determination of heights of these structures are given. The RPC model is considered as a model for the orientation of bush-broom images. Shift corrections for the «Pleiades» bush-broom images and affine corrections for the «Resource-P» bush-broom images are used for the RPC model refinement. The proposed method of the buildings height’s determining does not require too much geodetic works or the presence of stereo pairs for the stereo measurements. Having high-quality ortho images and DEM as a high-raise basis and a single off-nadir image for the specified work area is necessary to implement the proposed method.
