Radiometric Calibration

Hi,

I am trying to understand the process of Radiometric Calibration. Given a radiometric calibration target and the Albedo values for all bands of interest, how to apply this information to get a radio-metrically calibrated image. What is the formula to apply radiometric calibration?

Thanks

Hi, 

In order to apply the radiometric calibration to your project, you can set the Albedo values of your radiometric calibration target in the Processing Options of the Index Calculator, as described here: https://support.pix4d.com/hc/en-us/articles/203891879#label3 

The formula that applies the radiometric calibration to the images takes into account several parameters and varies depending on the correction you apply (“Camera”, “Camera and Sun Irradiance”, “Camera, Sun Irradiance and Sun angle”).
