iPi Soft Announces iPi Motion Capture Version 4

Advanced Markerless Mocap Solution Delivers Real-time Tracking For 3D Character Content Creation, Compatibility With Leading Sensor Technologies, GoPro Camera Support and New Perpetual License Model


MOSCOW, RUSSIA – July 3, 2018  – iPi Soft, LLC, developers of advanced motion capture technology, today announced iPi Motion Capture Version 4 a comprehensive next version of its popular markerless motion capture software. Version 4 introduces a highly anticipated real-time preview capability for a single depth sensor.

Other new features and enhancements in Version 4 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 like GoPro and SJCAM. With Version 4, iPi Soft also introduces a perpetual license model.

We are delighted to introduce real-time tracking feedback in Version 4 that allows users to preview the motion tracking result transferred to 3D characters at the time of performance, Michael Nikonov, iPi Soft founder and chief technology architect, said . The combination of real-time tracking, expanded support for the latest in depth sensor technology and wide-angle action camera compatibility in Version 4 elevates the content creation experience for high-end film, television and games customers where a fast and reliable workflow is essential.

Benefits of iPi Mocap V 4 Real Time Tracking

The new real-time tracking feature in Version 4 uses iPi Recorder, a free software provided by iPi Soft for capturing, for playing back and processing video records from multiple cameras and depth sensors, to communicate to iPi Mocap Studio software that tracks in real-time speed 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 to provide end users with an accurate, flexible and efficient workflow.

iPi Mocap Version 4 currently includes the real-time tracking feature for a single depth sensor only. iPi Soft is scheduled to bring real-time functionality for multiple depth sensors by the end of this year.

Development of plug-ins for popular 3D game engines, including Unreal Engine and Unity, is also underway.

Key features in iPi Motion Capture 4

Real-time Tracking and Other Tracking Improvements

  • Real-time 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, users can re-do tracking for selected body parts, which allows users to fix tracking errors more quickly.
  • Tracking improvements of head and hands, when used in conjunction with Sony’s PS Move motion controller that takes into account joint limits.

Support for New Sensors and Cameras

  • Support for Intel RealSense D415 / D435 depth cameras, Asus Xtion2 motion sensors and Orbbec Astra / Astra Pro 3D cameras.
  • Support for action cameras like GoPro and SJCAM, including wide-angle cameras, which allows users to come closer to camera thus decreasing space requirements.
  • Ability to calibrate individual internal parameters of any camera, which can be used to correctly reconstruct 3D information from video for improved overall tracking quality.
  • 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.
  • With support of action cameras, video framerate can reach up to 120 fps to allow for tracking extremely fast motions.
