Finally, latitude and longitude coordinates (α is judged respectively1,β1), (α2,β2), (α3,β3) whether with the pixel before projective transformation
The latitude and longitude coordinates of point are corresponded, and are (α due to latitude and longitude coordinates being not present on the digital satellite cloud atlas before projective transformation1,
β1) pixel, you can it is the estimation point (that is pixel A is numerical value vacancy point) of pixel to learn pixel A, and
The estimate that linear interpolation processing obtains pixel A is carried out according to the pixel B around pixel A and pixel C value, so
Afterwards, the color for determining pixel A according to pixel A estimate repairs digital satellite cloud atlas.
By the method for above-mentioned reverse Mapping and space interpolation it is possible to prevente effectively from after projective transformation, because the difference of coordinate
And the numerical value vacancy of rear region augmenting portion is converted caused by the change of viewing area scope, further, since before conversion
Pixel distribution is regular distribution and pixel has uniqueness, so interpolation model is simple, so as to reduce interpolation difficulty, keeps away simultaneously
Pixel " overlapping " phenomenon is exempted from so that the cloud atlas drawn out is more accurate.
