Constraints including attitude

[2tall3ne]

I am coming from another application that allows importing constraints such as position, yaw, pitch, and roll...this is extremely important for our metrology projects.
I tried to import these constraints and it only allows X,Y,altitude, no yaw, pitch or roll. How will I achieve this? This is stopping is from moving to 3DF Zephyr.

Hi, you can load photos with known parameters (generally in the context of fixed rigs) using the XMP workflow, see this tutorial as reference: https://www.3dflow.net/technology/do...flow-tutorial/

Hi Alessi,

This is far more complicated than our current workflow for simpler projects. We may be able to pivot to this with our high-accuracy metrology projects when we are using our in-house camera, but I want to import constraints/references for each camera and have the software determine intrinsic values through its automatic algorithm and refine extrinsic values from the initial constraints. For certain subsea site survey projects, we will have INS positioning/attitude with a client camera and will not have intrinsic/extrinsic values but can use the camera poses as a starting point and have the software do refinement.

We tend to run processes in the field, and the ideal workflow is a single file exported from our navigation into the photogrammetry software, which we currently do in a competing application.

I am trying to convince multiple "very high-ups" that 3DZephyr is an excellent alternative to software that starts with "M," but this is a dealbreaker.

I do hope there is a simple workflow to achieve what I am asking for.

Regards.

you can use the "load photos from known parameters" if you really want to, but unless you have very accurate RPY, then it would be a placebo effect to have you had it input them, unless I'm missing a step here. Feeding XYZ position should be enough. Feel free to reach out to support@3dflow.net if you have a particular dataset / use case you need help with, we'll be happy to help.
