Hi @HanzDieter Each stream will use the bit depth of the particular format that it is set to. So if Z16 depth and Y8 infrared is used together, the streams would be 16-bit and 8-bit respectively. Only 16-bit is available on the depth stream, whilst infrared can be set to 8-bit or 16-bit. On the D405 camera model you can set infrared to 16-bit Y16 but doing do automatically disables the depth stream. You can set 16-bit Z16 and 16-bit UYVY at the same time on D405. UYVY produces an infrared-like monochrome color image. https://www.theimagingsource.com/en-us/documentation/icimagingcontrolcpp/PixelformatUYVY.htm
If you require depth, infrared and color simultaneously then color can be set to YUYV (not UYVY), resulting in an RGB color image in that format.

You can use 1280x720 instead of 848x480 for all three (Z16 depth, UYVY infrared, YUVY color). For the depth stream, 848x480 is the optimal resolution for depth accuracy but you may find 1280x720 satisfactory.
Because RGB comes from the depth sensor on D405 because it does not have a separate RGB sensor component, 1280x720 color will be the best that you can get as 1920x1080 Full RGB is not supported on the D405 model. The RealSense depth stream cannot have its bit rate changed. It is always 16 bit. Some RealSense users have converted 16-bit RealSense depth to an 8-bit OpenCV mat in the past though. An easier way to free up processing may be to use a post-processing Decimation filter to 'downsample' the depth image to a lesser complexity. |
