Radiometric Aerial Triangulation

Aerial image acquisition results in a collection of frames that cannot be seamlessly integrated into a mosaic. Individual frames in a collection will vary depending on camera angles, altitude, position of the sun, atmospheric interference (especially if taken at high altitude), and many other factors.

Radiometric aerial triangulation (Radiometric AT) compensates for the measurable phenomena that create image differences. Once this correction is done, a model will be created to allow it to adjust each frame simultaneously to minimize the variation within a whole mosaic. The result of this process is individual frames of higher quality that fuse seamlessly into a mosaic. 

I2R has developed automated software that optimizes the individual adjustments to each camera in order to create a seamless mosaic, without unwanted gradients. The final product of I2R's radiometric aerial triangulation is a higher quality collection with consistent colors across all frames integrated into a mosaic.
