record or extract raw left and right RGB images from D435i

Hi,

I'm trying to record videos and capture images that include both depth and RGB images.  For the RGB images, is there a way for me to capture both left and right raw RGB images of a scene? Or can I extract left and right views from pre-recorded/pre-capture RGB video/image?

A little bit background.  I'm asking for a way to do this just in case I don't do a good job of tuning the parameters for capturing depth map of a scene; with the raw left and right views, I can always use outside algorithms or packages to extract a more accurate depth map.  This is my backup plan as the scene I'm trying to capture is not always and easily available to me.

 

Thanks!

    Raw RGB can be provided in a RAW Bayer format, which is recognized by Librealsense as a format called V4L2_PIX_FMT_RW16

    Although recognized by the RealSense SDK as a legacy format for the sake of back compatibility, I don't believe it is accessible through the SDK by the user.

    Regarding your wish for both left and right RGB: a member of the RealSense support team has said "For the RealSense D41x, the RGB stream is available only via the "left" IR imager.  Left and right IR imager on the D43x series camera are monochrome sensors; hence, no RGB color".
