What does it mean "it reads my cameras' lens"? What reads what?ģ. However, even with the older version, one needs an actual image to get the parameters.Ģ.
#Ptlens profile trial
Do you mean with "free version" the trial version of PTLens? The older version displays the lens geometric distortion parameters, the newer one does not. I tried to I understand your questions, but I'm not sure if I succeeded pls correct me if I started out from the wrong point.ġ. I have the "free" version, but it reads my cameras' lens. the distortion was not corrected.įacit: use the geometric distortion parameters supplied by PTLens, don't let PT calculate them. However, when I had PT calculate the lens parameters based on six straight lines around, close to the edges, the calculated lens distortion parameters were not even close to those from PTLens, and the stitching result was almost identical to the source, i.e. When using the parameters I got from PTLens, the result was virtually perfect, at the edges as well. I shot a grid (nested rectangulars) and used PTA to "stitch" a single image. Now I made some tests with my Sigma 20mm, which has a pronounced distortion. You mentioned on the PTAssembler 3.5.0 Beta 2 thread, that you are not sure, how well the distortion correction works close to the edges. Update: I removed "for Buho" from the subject line, as this discussion became more generic. However, the real problems are somewhere else, see later. Update: I found, that the phenomenon we are discussing here is not geometric but curvilinear distortion.
