Blue eye calibration software11/13/2022 ![]() ![]() The images are ordered from left to right as blue, green, red, red edge and near infrared. Below is an example of the grayscale images of raw data captured with the RedEdge-MX: What is Radiometric Calibration and Why is it Important?Īlthough we generally visualize multispectral imagery as colorful indices or composites, the actual images that come out of the camera are grayscale and are essentially matrices of digital numbers. Hopefully, after reading this you will understand conceptually how changes in day-to-day light conditions can impact the accuracy of multispectral data and what tools are available to improve radiometric accuracy. The value of radiometric calibration can be a bit difficult to understand, so we’ve put together this article in an attempt to add clarity to the topic. ![]()
