almost ready to move to the reconstruction phase (helmet project)

Hi Youri,

yes, how you describe the workflow as it is described is correct in my understanding.

However, 1px max repro error is not a magic trick. It might helpin some cases or not, like in your case. What it does is it tells RC to discard all tie points with an initial repro error of 1 and higher. That means much less to chose from. Raising the value might be worth a try as well.

Anyway, figuring out how to get the best result from your dataset is basically doing the bulk of the work. This is the art of taming RC. So you need to either try it out for yourself with the help of many useful forum-threads that cover many of your questions or you need to provide some more info (see my other posts in your threads) and hope that somebody has some pointers for you…
