High Speed Videography


Stanford Reference:

04-192


Abstract

Stanford Researchers have patented an improved technique for capturing and processing dynamic and high speed scenes using a collection of precisely timed video cameras. This system uses multiple synchronized image sensors with precise time delays to capture high-speed video. If the cameras are closely packed together, the system can be used as a continuously streaming high-speed camera. If the cameras are spread further apart, the system can be used to capture multi-viewpoint video of dynamic events (sports, performances, etc) at effectively higher frame rates without using expensive high-speed cameras and capture systems. Capturing with a higher effective frame rate simplifies space-time view interpolation creating new images of a scene that appear to have been taken from a place and time not in the captured set of images. An example would be slow-motion replay from a smoothly varying virtual camera position.



Applications


  • High-speed videography
    • Sports: for analysis of athlete's performance or competition finishes
    • Medical testing
    • Dance: for analysis of dancer's motion
    • Military test and evaluation
    • Industry trouble shooting: manufacturing, vehicle impact testing, ect...
  • Movie special effects
  • Enhanced video playback for consumer television

Advantages


  • Enables continuous streaming
  • Longer capturing duration: minutes instead of seconds of video capture
  • Eliminates the need for a trigger
  • Cost-Effective: eliminates rolling shutter distortions allowing the use of inexpensive CMOS sensors
  • Modular & Scalable – can scale to higher speeds by simply adding more cameras to the array
  • Processing of new visual outputs with minimal computational load
  • Flexible
  • Capture from widely spaced cameras with staggered trigger times enabling playback of real, live scenes from a variety of angles and varying speed for sports, dance, and other action filled scenes
