Question, WebODM and Roof measurement accuracy
I have a question regarding the accuracy of using DJI mini 5 pro without gcp to measure roof.
My method is I take more than 15 photo have more than 70% overlap with each one, same heigh, and sometimes i just randomly go back to take a couple of picture randomly.
example, from front house to back around 15 photo, then i go from back to front like another 5-6 photo.
How accurate is the measurement, like the plus-minus measurement error.
Quick look at the google some say it like 10cm+-, and some even say up to 6 meter. But my understanding is that the 6 meter is more of the position error relative to the real world rather than what i want the roof measurements. Does what I say make sense?
also I think it also depend on the heights of the image capture, house usually I think below 9 meters anyway so it is good way to measure roof?
