Inconsistency with D415
When I view the live depth readings from my D415, there is a lot of variation in my image data. In other words, the data is changing quite a bit, even when the image is completely stationary. This effect is exacerbated the closer you get to the edge of the image. This results in my frame captures to be quite noisy, making it hard to extract real data from the image with any kind of consistency. I have tried taking multiple captures and averaging as well as applying filters to the depth in postprocessing, but none of it really removes the problem. I have also tried using the camera in all types of settings (light/dark, far/near, etc.) and the problem persists through all of them.
Is there any way to fix this?
I also noticed that there is always a somewhat significant bar of invalid data on the left side of the image. What is the reason for this?

Hi Dpalumbo573. The strip of invalid data at the left edge of the image is normal and is called the Invalid Depth Band. Page 79 of the current edition of the data sheet document for the 400 Series cameras provides information about it.

In regard to depth fluctuations, the depth reading can be made more stable by using a Temporal Filter post-processing filter and setting its Smooth Alpha to a low value such as '0.1' instead of its default value of '0.5'.
There may be factors in the environment of the location that the camera is being used in that may be contributing to the fluctuations though. Could you provide an RGB image of the scene to help to identify elements in the scene that are potentially disruptive, please?
