Clarification on light-field data accessibility in ULTRIS X20 (CUVIS SDK)

[juhyc]

Hi,

After resolving the recent SDK setup issues and starting our experiments
with the ULTRIS X20, we would like to ask for clarification regarding
the level of light-field / angular data that is accessible through the
CUVIS SDK for research purposes.

We are using ULTRIS X20 for hyperspectral 3D reconstruction research.
Since ULTRIS X20 is described as a light-field based snapshot hyperspectral camera, we would like to better understand what data representations are available to the user.

Specifically, we would like to ask the following:

1. Does the CUVIS SDK provide access to raw sensor data prior to hyperspectral cube reconstruction, such as micro-lens based micro-images, sub-aperture views, or angular/light-field samples?

2. If raw micro-image access is not available, is it possible to export sub-aperture views or any form of multi-angular images corresponding to different light-field directions?

3. Is the delivered hyperspectral cube (e.g., 410×410×N spectral bands)
   already fully integrated over angular dimensions, or does it still
   implicitly encode angular/light-field information that could be decoded
   for applications such as depth estimation or digital refocusing?

4. Are there calibration models or documentation available that describe
   the mapping from sensor pixels to rays (position, angle, wavelength),
   which would enable light-field-based depth estimation or refocusing
   in research applications?

5. If direct access to angular/light-field information is not supported,
   would ULTRIS X20 be officially recommended to be used as a snapshot hyperspectral camera only, with 3D reconstruction relying on
   camera motion and multi-view geometry instead?

Our goal is to understand whether ULTRIS X20 can support single-shot or multi-angular light-field depth cues, or whether multi-view acquisition
is the intended and recommended approach for 3D reconstruction in
research workflows.

Thank you very much for your time and clarification.

Dear Juhyung Choi,

thank you very much for your request.
I kindly ask you to submit this as a SDK specific/sensitive data request in our Help Center.

Best regards,
