Close Range Project with partial fixed Camera Orientations

[Marcoo]

Hi there,

I'm trying to align two sets of photos for indoor 3D-reconstruction:
One from a standard DSLR without information about their position and one from the camera system of a tachymeter, whose position and orientation is exactly known and should not be changed. The idea is to resign manually measure control points.
My first idea was to set the accuracy of the camera positions to zero, but this isn't true for those photos without known position/orientation. What do you mean?

I'm glad to read your meanings or ideas
Marco

Hi Japper, have some data to see intro the problematic ??

Thanks for your response.
I uploaded a PhotoScan project with a small set of images (30MB) from a flight session last year.

The Zip-archive contains also some exports (camera exports in different formats and the adjusted camera calibration).
I created a new project and imported some images. Then I imported the external orientation ("import cameras..."), but only from a part of these images. The idea was to align the rest of the images (7239 and 7264) without changing these with the imported external orientation (7424, 7425, 7507, 7508, 7509). Technically, this is the same thing I want to do with the mix of tachymeter and DSLR images.
Notice: I didn't cut the external orientation of 7239 and 7264 from the exports in the Zip-archive yet.
Do you think this could work? Till now, PhotoScan always changed all of the external orientations.
