Editions Comparison
Q: Which configuration do you recommend: Dual depth sensors or Multiple Sony PS Eye?
A: There is no straighforward answer to this question, there are pros and cons each option: Dual Depth Sensors vs Sony PS Eye Comparison
Q: What is the difference between Express Edition and other editions?
A: Express Edition:
- supports only 1 depth sensor
- capture volume will be 7 by 7 feet (approx. 2 by 2 meters)
- you will not be able to track complex motions that include rotations because of self occlusion.
- but you will not need multi-camera system calibration, that makes Express Edition much easier in operation compared to other editions (that are multi-camera)
- Express edition also uses our own markerless tracking algorithms that give much better tracking quality than Microsoft Kinect for Windows SDK
Basic and Standard Editions:
- support of 1 depth sensor is included in Basic and Standard Editions as well
- support of 2 depth sensors will allow you to capture more complex motions than with 1 depth sensor, including rotations
- Sony PS Eye cameras-based set-up is the most powerful option: it will allow you to capture very complex motions in much bigger capture volume - 20 by 20 feet (approx. 7 by 7 meters)
Q: What is the difference between Basic Edition and Standard Edition?
A: Standard and Basic both support dual depth sensor configuration, and other basic motion capture features. They differ by features:
- Maximum number of Sony PS Eye cameras (or other compatible cameras). Basic supports 3 or 4 cameras, Standard supports 3 to 6 cameras. 6-cameras set-up will allow you to track wider range of complex motions (including rotations, like fighting, dancing etc.) with good quality (more robust, more accurate).
- Standard will support multiple persons tracking (release of this feature is planned for May, 2013). Basic will not include this feature.
Q: What is the minimum space required for capture?
A: For 1 or 2 depth sensors you will need 9 by 5 feet (3.5 by 2.0 meters). For webcameras-based multi-camera system you will need 13 by 13 feet (4 by 4 meters)
