Mutli Camera Angle Mocap

Ok, so I’ve been playing around with camera tracking and watched a few videos on object tracking. I was wondering if it is possible to have multiple video tracks on the same scene from different angles. Is it possible to do this and use them to simultaneously solve all the tracked points instead of merging multiple tracks. I’m hoping this increases accuracy and reliability. I want trackers from multiple angles to be synchronized together for the solution.

If this cannot be done in blender, is there any other free/cheap software out there that does human motion capture the way it is done professionally, by major video game designers? Can anyone explain if the way i want to do it is even the same as them, and provide any tips on properly achieving an accurate Mocap?
