Hi. I’m asking for help as I’ve been stuck on Stereo Camera Calibration for a couple days now with no answers.
After some trial and error, I succeeded in getting the command lines on the guide site( Stereo Camera Calibration and Tools | Epic Developer Community (epicgames.com)) to work, and also succeeded in pulling a capture source that I could import into UE.
However, the imported result is not normal to say the least - it looks like a modern art piece using clay.
I don’t know if it’s because of the noise, if the depth data is wrong, or why the whole frame feels skewed.
As I experimented, I tried to improve each suspicious element, but the result was almost no different.
Here are some of the improvements I made.
-I used a custom calibration board and then printed out and used the calibration board provided on MetaHuman site.
-Aligned the two cameras on stereo HMC vertically instead of horizontally.
-Shortened the lens rig so that the face is larger in the camera’s field of view: Nose clipped in the latest capture source because the lens is too close to the face
-I also tried changing ‘-n 30’ to ‘-n 60’ when entering the CalibrationApp command line.
-Converting the .png files output from the data conversion with mh_ingest_convert.py to .exr files before entering the CalibrationApp command line.
I searched and tried this and that, but all of them failed. Sadly, there was very little documentation to refer to. 
There are a couple of things I’m not sure about in my experiment, and I’m not sure if they’re the cause of the problem.
- when I converted the data with mh_ingest_convert.py, the output file type was .png, is that correct?
- are the warnings I get when I enter the data conversion command line the problem?
If anyone has encountered a similar problem, or has any clue what’s going on, please respond.
