This claims to work with monocular or RGB+depth but the only live demo is for an Intel Realsense d455 RBGD camera. That seems a shame as it significantly raises the bar for people to try it out themselves. (Can you even still buy the d455?)

I assumed that the algorithm only uses the RGB sensor and the depth is ignored. I bought two d455 within the past year and they are quite nice.

Seems it can use both, if available.

Their model works on both. RGB only performance is comparable to other depth based methods which is why they emphasized it over the RGB-D version.

Most iphones since iphone x have truedepth camera sensor in front that could be used instead of realsense I guess. However since iphone 13 quality of those depthmaps got more noisy. You can try with record3d to stream such rgbd data to your laptop via USB and use in python https://github.com/marek-simonik/record3d/
