In reconstruction settings you can set Minimum Cameras to Start Trajectory
to 2 (default is 2) and Store Ray Contributions to False.
In Axiom Labeling Settings
Joint Ranges Slack default is 1, DO NOT go over 1.5, but 1.2 might be for a
very flexible actor. The lower value will be more accurate.
Booting quality leave as is – zero will be doing best for system
Under Solving Settings: Turn Extrapolate finger data on to True
This only applies if you are using the Post (Axiom) Processing
Enhance your camera calibration and post-processing skills with this comprehensive guide. Ensure proper settings and follow step-by-step instructions for accurate results. From unrolling rotation curves to solving motion, this guide covers it all. Utilize tools like auto masking, wand wave data collection, and marker editing for precise calibration and reconstructions. Make the most of studio activities and post-processing tabs to streamline your workflow. Whether it's setting origin points or calibrating floor planes, this guide has you covered for optimal camera setup and data processing.
