D455 vs D435
D455 can sense depth farther than the D435 but has a equal pixel resolution, how is that possible?
-
Hi Chicagobob123 The D455 has 2x the depth accuracy over distance of the D435 model. So the D455 has the same accuracy at 6 meters as the D435 has at 3 meters.
The D435 and D455 have different minimum depth sensing distances (MinZ). The D435 has a minimum depth distance of 0.1 meters, whilst the minimum depth distance of the D455 is 0.4 meters.

Hello Chicagobob123,
What enables the D455 to detect depth further than the D435 is the longer baseline of the D455, which is the distance between the two depth senors.
D435 Baseline: 50mm
D455 Baseline: 95mm
The longer the baseline, the further the camera can detect depth.
Sincerely,

It would be interesting to make the baseline adjustable so it can be extended based on need.
Currently its 3.74016 inches, following your logic if you made it about 1 foot baseline it could see 4 times
farther or about 120 feet. That would be useful for many.
The feature set and feedback are great. The 455 has the T265 data and pose information built into it right?
-
Yes, a longer baseline would allow depth sensing much further but trade-offs have to be made based on target usages.
The T265 is the only camera that provides pose information.
The D435i, D455, and L515 have built-in IMUs which provide gyro (angular velocity) and accel (angular acceleration) data only, no pose.
