Marker-less motion capture is advanced technology using computing power and ingenuity to track people, instead of tracking markers. It increases usability as anyone can just hop in the system and generate data. A typical tracking outfit day-in and day-out can be as simple as jeans and a tee-shirt. While we constantly improve our algorithms to track better there are still some general rules to keep in mind so you can make the most of your motion capture sessions.
The best way to think about this is consider you are the motion capture system. The system needs to take the images it sees (as you can see in the camera views) and not only find a person, but identify a skeleton within that person. If it makes it easier for you to see, it is easier for the system.
If you were wearing baggy pants or a puffy shirt, just as a computer might, you would have a difficult time identifying where your actual body was below the cloths. Additionally, if that puffy shirt was white against a white background you would have an even trickier time. So in general if you aren't getting perfect tracking results, step back and evaluate if you are inadvertently "tricking" the system into making mistakes. If you think you might be, or just want to get the best results every time, use the following guidelines:
- Wear form-fitting cloths (save your Aloha shirt and parachute pants for some other time)
- Differentiate yourself from the background -- strong dark colors against a bright white background is recommended.
- Don't forget your feet. Whether wearing shoes or socks, the system needs to see them too.
