I have been collecting imagery from a MicaSense RedEdge camera, a multispectral camera made for attaching to sUAS. https://www.micasense.com/rededge/.
This camera also comes with a calibration target that I took pictures of before each of my sUAS flights ,and the calibration target has a laboratory measured reflectance value for each camera band.
However, now I am struggling with how to use the calibration target to convert the DN of the imagery to reflectance value so that the imagery can be compared between different times. I also have access to information on the date and time of day that the imagery was taken, as well as solar irradiance values for each image.

Hello Kelsey. There are a number of articles in our knowledge base that can help. For instance, this one:

Easiest way to get reflectance compensated outputs is using Atlas. Pix4D Mapper will also work using the proper workflow.
Send us an email at support@micasense.com for further info.
