| |
| Infrared 10-bit linked with Depth 16-bit images |
| |
| |
| Description |
| =========== |
| |
| Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of |
| Infrared image followed by Depth data. The pixel definition is 32-bpp, |
| with the Depth and Infrared Data split into separate continuous planes of |
| identical dimensions. |
| |
| |
| |
| The first plane - Infrared data - is stored according to |
| :ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format. |
| Each pixel is 16-bit cell, with actual data stored in the 10 LSBs |
| with values in range 0 to 1023. |
| The six remaining MSBs are padded with zeros. |
| |
| |
| The second plane provides 16-bit per-pixel Depth data arranged in |
| :ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format. |
| |
| |
| **Frame Structure.** |
| Each cell is a 16-bit word with more significant data stored at higher |
| memory address (byte order is little-endian). |
