Creation of photoplan by several photos

This mode is applied at creation of photoplan from several fragments of different photos. Created digital orthophotomaps onto a separate nomenclature sheet frequently are located on several photos. In result on a place of photos joint the shift of the image is formed, that worsens photometric properties of the created photoplan. For minimization of received shift the technology of the report of rasters is used. As the report of rasters we understand process of additional transformation of crossed rasters with the purpose of minimization of a divergence of the image in places of a joint of crossed rasters. Accuracy of creation of the photoplan thus does not worsen.

The technology of creation of the photoplan from several rasters consist of several stages.

On the first stage the transformation of each source raster which fragment belongs to the nomenclature of the created photoplan is carried out.

On the second stage we carry out report of transformed rasters. For this purpose it is consecutive for all rasters, which must be subjected to the report the measurement of connecting points is carried out. After that the transformation of rasters by control points and the average coordinates of connecting points is carried out. As a result of these operations we receive the new transformed rasters with the minimized shift on joints.

On the third stage we unite reported rasters into one file of BMP format, we convert it into RSW format and we carry out cutting a raster by nomenclature sheets. To reduce volume of raster, you can optimize it.
