A technology for the radiometric correction of high spatial resolution imagery (aerial or UAV). The imagery is calibrated to approximate surface reflectance by fusing with concurrent and collocated satellite imagery. The technique allows the production of seamless mosaics corrected for coarse scale atmospheric and bidirectional reflectance distribution function (BRDF) effects and does not, like many existing methods, require the manual acquisition (or provision) of ground reflectance references.
Target Industries
This technology could find applications in various industries requiring:
- Remote Sensing
- Earth Observation
- Scientific analysis of areial and or UAV imagery.
Examples of potential target industries are forestry, conservation, and climate change.
Unique Features/Benefits
The use of high spatial resolution aerial and or UAV imagery is limited by radiometric variations cased by atmospheric and BRDF effects. The variations creates discontinuities and gradients between and within images, and inhibit their use for quantitative analysis.
This technology corrects the radiometric variations without the need for manual field relectance measurments, the placements of targets of known reflectance, or detailed knowledge of atmoshperic conditions. The technique is relatively computationally efficient and can be applied to large moasaics of imagery consisting of thousands of image.
