The Photography Stack Exchange site is about the art and science of photography, which is the making of images with light.
Many people want to use consumer cameras as sensors and measuring devices, which seems reasonable because the are ubiquitous and cheap. But because they are made for photography, they're not really geared for this kind of thing. Answering questions about how a consumer camera is not really working well for machine vision or scientific analysis is repetitive and tedious. And it's not really any more on topic than someone asking
I want to weigh a bag of rice and I don't have a set of weights, so can someone tell me how heavy the Canon 5D is?
or
I have a bunch of nails and need to hang up some pictures. Which lens is best for hammering them in?
Sure, those are about about camera gear, but it's not about photography. The site isn't https://camera-gear.stackexchange.com/.
Additionally, these are usually one-off questions, or a series of questions around the non-photographic use case. They don't help build a community of practice around actual photography.
Perhaps there is room for a site about computer vision where these kind of things would be on topic. But if there's a question about image processing or measuring things from image metadata or anything like that, please don't send the questioner to Photography.SE. That just makes everyone frustrated.
