@Yonatan (including @user2 since it looks like you are working on the same thing), can you share some more details about your setup and workflow?
- Which
camera and(A7Riii) model of lens are you pairing to the sensor? - Which recording settings are you using to capture the pairing samples and clips? Codec, file container format, resolution, sensor crop, etc.
- Are you transcoding or converting the files before ingesting them into Depthkit during the pairing process?
- How is the camera mounted to the sensor? (Do you have pictures?)
- What is your sampling strategy - Where are you positioning the chart relative to the sensor/camera, how far is it? Where is it in the frame? Which way is it facing?
- Which depth resolution is the sensor set to when sampling? From the screenshot, it looks like a WFOV mode, but is it 512 Binned, or 1024 Raw (15 Hz)?
- Are you getting any errors once you generate the intrinsic lens calibration with Adobe Lens Profile Creator - even when using the digital display rather than the printed chart?
The Pairing Accuracy metric generally accumulates as you add more and more samples. If it doesn’t increase with additional samples, it’s possible the underlying intrinsic calibration generated in the Adobe tool could be invalid. But if it does increase with more samples, I recommend adding up to a total of 25-35 pairing samples.
