Depth sensor confidence information as a 4 bits per pixel packed array
|
|
|
|
Description
|
|
===========
|
|
|
|
Proprietary format used by Intel RealSense Depth cameras containing depth
|
|
confidence information in range 0-15 with 0 indicating that the sensor was
|
|
unable to resolve any signal and 15 indicating maximum level of confidence for
|
|
the specific sensor (actual error margins might change from sensor to sensor).
|
|
|
|
Every two consecutive pixels are packed into a single byte.
|
|
Bits 0-3 of byte n refer to confidence value of depth pixel 2*n,
|
|
bits 4-7 to confidence value of depth pixel 2*n+1.
|
|
|
|
**Bit-packed representation.**
