So recently I've been given the task to be able to make measurements of objects displayed in the panoramas. I've found this old topic, needless to say that this subject isn't an easy one. I now understand, that just by using a single image it's impossible to do. However, we're open to any suggestions and solutions? Have any of you ever did something like this in practice? I've looked up a lot of material about this online, but it's all quite confusing at the moment. Perhaps any ideas on how to proceed if say we had two shots of the same location? Btw, it doesn't have to be an automatic process, manual input (like selecting the corresponding points on the two images) is fine as long as we get a good result. We also obviously have access to camera parameters, such as focal length, sensor size, height of the tripod etc, whatever is needed.
Any help is greatly appreciated! Thanks!
