iPi Soft, makers of motion capture technology, has introduced iPi Motion Capture Version 4, the next version of its markerless motion capture software. Version 4 includes realtime preview capability for a single-depth sensor. Other new features and enhancements include support for new depth sensors (Intel RealSense D415/D435, ASUS Xtion2 and Orbbec Astra/ Astra Pro); improved arms and body tracking; and support for action cameras such as GoPro and SJCAM. With Version 4, iPi Soft also introduces a perpetual license model.
The realtime tracking feature in Version 4 uses iPi Recorder, a free software provided by iPi Soft for capturing, playback and processing video records from multiple cameras and depth sensors, to communicate with iPi Mocap Studio software, which tracks in realtime and instantly transfers motion to 3D characters. This allows users to see how the motion will look on a 3D character and improve motion accordingly at the time of acting and recording, without the need to redo multiple iterations of acting, recording and offline tracking.
Live tracking results can then be stored to disk for additional offline post processing, such as tracking refinement (to improve tracking accuracy), manual corrections and jitter removal.
iPi Mocap Version 4 currently includes the realtime tracking feature for a single depth sensor only. iPi Soft is scheduled to bring realtime functionality for multiple depth sensors to users by the end of this year.
Development of plug-ins for popular 3D game engines, including Unreal Engine and Unity, is also underway.
Tracking Improvements include:
• Realtime tracking support of human performance for live preview for a single-depth sensor (Basic and Pro configurations). Motion can be transferred to a 3D character.
• Improved individual body parts tracking, after performing initial tracking, allows users to re-do tracking for selected body parts to fix tracking errors more quickly.
• Tracking improvements of head and hands when used in conjunction with Sony’s PS Move motion controller takes into account joint limits.
New Sensors and cameras supported include:
• Support for Intel RealSense D415 / D435 depth cameras, Asus Xtion2 motion sensors and Orbbec Astra / Astra Pro 3D cameras.
• Support for action cameras such as GoPro and SJCAM, including wide-angle cameras, allows users to come closer to the camera decreasing space requirements.
• The ability to calibrate individual internal parameters of any camera, helps users to correctly reconstruct 3D information from video for improved overall tracking quality.
• The ability to load unsynchronized videos from multiple cameras and then use iPi Recorder to sync and convert footage to .iPiVideo format used by iPi Mocap Studio.
• Support of fast motion action cameras — video frame rate can reach up to 120fps to allow for tracking extremely fast motions.
Version 4’s perpetual license is not time-limited and includes two years with full support and software updates. Afterwards, users have the option to subscribe to a support plan to continue receiving full support and software updates. Alternatively, they can continue using their latest software version.
iPi Motion Capture Version 4 is also available as a subscription-based model. Prices range from $165 to $1995 depending on the version of software (Express, Basic, Pro) and the duration of subscription.
The Basic edition provides support for up to 6 Sony PS3 Eye cameras or 2 Kinect sensors, and tracking of a single actor. The Pro version features full 16-camera/four depth sensors capability and can track up to three actors. A 30-day free trial for Version 4 is available.
