0 depth at the left of depth image even after performing alignment
I'm using D405 and opencv C++. Resolution is 848 x 480. The top image is the color image and the bottom image is the colorized depth image. The foreground object in the images seemed aligned after I performed alignment as described in rs-align. However, I'm curious about the black pixels at the left of the depth image. Can anyone tell me if this is sort of expected? Can I get rid of these black pixels?
Hi Dhongfhel The black area without depth on the left-side of the image is normal and is a phenomenon called the Invalid Depth Band. Page 82 of the current edition of the data sheet document for the 400 Series cameras has information about it. The width of the band should decrease as the camera is moved further away from the scene that it is observing, though on the D405 camera model doing so may not be practical due to its close depth-sensing range.
Hi MartyG Thank you for this helpful information. I can see its width decreases as I move the camera farther. But yeah, I need it closer to the object that's why I picked D405 for this purpose. I guess I'll just have to crop that part off the depth image. Thanks again.
