HYBRID PRECISION TRACKING

摘要

Disclosed herein are through-the-lens tracking systems and methods which can enable sub-pixel accurate camera tracking suitable for real-time set extensions. That is, the through-the-lens tracking can make an existing lower precision camera tracking and compositing system into a real-time VFX system capable of sub-pixel accurate real-time camera tracking. With this enhanced level of tracking accuracy the virtual cameras can be used to register and render real-time set extensions for both interior and exterior locations.

主权项

1. A hybrid through-the-lens tracking system, comprising:
a first system that includes a calibrated look-up table and is configured to use the calibrated look-up table to modify search locations for scene markers when using adjustable lenses for motion picture and television visual effects production; the first system is configured to transmit predicted 2D locations of the scene markers to a second system; and the second system is configured to use a high speed GPU-based scene marker detection scheme that uses a fast geometry based search to calculate the predicted 2D locations of the centers of the scene markers.
