Mike Tully, CEO of ASI provides an interesting look at a number of technical issues concerning the use of what he terms a “flying camera” in this article from a recent newsletter. Here’s an excerpt:
“Drones operate in an inherently unstable atmosphere under constant, random motion where lighting conditions can vary continuously and dramatically. Resolving power is a measure of how much detail is discernable in photography (Figure 1). The ultimate resolving power is a product of not only the quality of the camera and lens but also the performance of the entire “camera system”. These and other factors affect the ultimate detail visible in drone photography.
Clarity of detail is often needed to accurately measure or map visible features. Clarity (high resolving power) also has a direct impact on the ultimate positional accuracy of the orthophotography generated from the aerial photography. As budding new drone operators or consumers of these professional services we need to understand these fundamentals of remote sensing and mapping.”
Mike explains that resolving power and resolution are not the same thing and that there is no direct relationship between the two.
Definitely worth the time to read.
