DI4D Head-Mounted Camera Optimized for 4D Facial Performance Capture

LOS ANGELES — Facial performance capture company DI4D has unveiled a new version of its wireless head-mounted camera system, which is now available.
The DI4D HMC is the culmination of DI4D’s many years of experience in developing and using head-mounted camera systems. It is a high-end solution for facial motion capture designed to deliver the highest quality data under high-pressure production conditions, and all while maintaining a high degree of actor comfort. The DI4D HMC is the only commercially available HMC that’s optimized for 4D facial performance capture using DI4D’s post-processing service. It is also compatible with third-party facial animation solutions.

The DI4D HMC is fitted with a stereo pair of high-quality 4MP cameras and a fine focus adjustment mechanism to ensure that captured images are always as sharp as possible. The onboard diffuse LED lighting panel ensures that illumination is as even as possible across the actor’s face. 

Synchronizing the lighting to the cameras reduces the apparent brightness to the actor, while still allowing capture with an aperture of F/2.5 for better depth of focus, short exposure to minimize motion blur and low gain to reduce image noise. Continuous wireless synchronization ensures that multiple HMCs remain accurately synchronised to master timecode at up to 60fps.

The light-weight, flexible open headband-based design ensures a comfortable fit for actors while the carbon fibre boom provides excellent rigidity and camera stability. The quick-release wire tension system ensures that helmets can be removed and fitted quickly and repeatedly. The rechargeable battery provides up to 3 hours of continuous wireless operation and is hot-swappable to ensure minimal interruptions while shooting.
DI4D’s intuitive DI4Dlive software makes it easy to control multiple DI4D HMCs remotely in a production environment. It offers a range of innovative features to simplify and speed up the process of setting up HMCs accurately and consistently for multiple performers and over multiple sessions. It also simplifies the process of monitoring, recording, reviewing and managing multiple takes across multiple DI4D HMCs. Additionally, DI4Dlive provides features to facilitate 4D performance capture, such as camera calibration and 3D reconstruction using stereo photogrammetry.
