11/25/2023 0 Comments Multispec 4c firmware![]() ![]() Sunlight sensor equals the lighting conditions during one measuring flight, while reflectance panel flatens differences in sunlight spectrum from one measuring to the next. The MultispeQ combines the functionality of a handheld fluorometer, a chlorophyll meter, and a bench-top spectrometer into one low cost, modifiable tool that brings lab quality measurements to field applications. Panel and sunlight sensors don't do the same things. Yes, we work with reflectance panels - in the rare time when we have a link between drone and rc. Whenever I calibrate the Green band everything works okay, but I have problem with the other channles. The only suggestion I could find that folks on the manufacturing end were thinking that we can get away without a reflectance calibration target was in the MicaSense Rededge FAQs (I paraphrase): Images were taken with multiSPEC 4C and the calibration target by AIRINOV which albedo values are already known by the manufacturer. Wondering if anyone has info regarding reflectance calibration workflows with the P4 MultiSpec camera array? The P4 MultiSpec has an on-board sunlight sensor, however with other MultiSpec sensors a reflectance calibration target tarp/board is still required, and formal research published on the topic pretty much demands the use of a reflectance calibration target for reproducible and thus comparable results. Is the P4 multiSpec sunlight sensor so amazing that reflectance calibration target board shots are of no additional value to the workflow? Would the accuracy/reproducibility of the imagery be better if reflectance calibration target board shots are incorporated into the workflow?ģ. Is a reflectance calibration target board/trap recommended for this sensor array?Ģ. So the questions (and I ask the same thing in a couple of different ways purely to ensure clarity):ġ. Although in he future we hope to develop the DSL sensors so the reflectance calibration target board shots are not required.'

'Q: if I use a sunlight sensor (DSL) do I still need to take reflectance calibration target board shots? A: Yes.
