Why don't depth cameras and SLAM techniques work?
- simcop2387 7y agoGenerally, the depth cameras don't provide enough precision in the data to be able to manage anything usable. If you want to scan an object to recreate something close it'll generally work ok but if you wanted to scan the object to build around it, and have things like up accurately then it's not good enough.
- Miraste 7y agoThey do work, just not well enough to be useful for scanning. I have a handheld infrared SLAM scanner, and when it encounters moderately reflective or dark surfaces, it interprets them as voids because they absorb or scatter the IR. Anything translucent or refractive is similarly a nonstarter. The surfaces it does scan are not very accurate (covered in slight bumps from inaccuracies). This means it can't scan most objects, and the ones it can scan still require a ton of cleanup.
- KaiserPro 7y agowell it looks like its a multiview structured light and another type of camera. So I suspect it is a SLAM system (how else can it make up an accurate mesh like that) but with a calibrated and well integrated depth sensor on there as well.
