I saw a 2 Minute Papers video that talks about the paper [0] I linked below. Basically the AI segments up the human body in to pieces. Using that data you could create a classifier for either pre-defined postures/positions or let it create its own classes (naive classification, I think?) Source [1] is a different kind of segmentation. I think your biggest obstacle will be training sets (assuming you want to use AI/ML). Once you've got training sets, the presence of obstacles (sheets/blankets) might not be so much of an issue.
