Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The smaller the radius, the larger the screen curve. In order to give more precise information about the curve of the screen, often the manufacturer provides data about the radius of this circumference. There are curved displays, whose curve is part of a circumference (arc). If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.Īpproximate height of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.Īpproximate width of the display. Often this is the rounded value of the actual size of the diagonal in inches.Īpproximate diagonal size of the display. Size class of the display as declared by the manufacturer. Sunlight sensor equals the lighting conditions during one measuring flight, while reflectance panel flatens differences in sunlight spectrum from one measuring to the next.Display Information about the main characteristics of the display - panel, backlight, resolution, refresh rate, etc. 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. 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): 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.
