Presentation Transcript


  1. Capture: Preliminary Experiment Instrumentation: • 2 Kinects (1 overhead and 1 side view) • 1st person audio/video: GoPro glasses on examiner • Boom microphone (fixed) • Consumer video camera • EDA on child and examiner Observations: • Activities with examiner/child take place across the whole room • Placement of fixed sensors must be studied carefully or activities more controlled • 1st person video • Go Pro $300 price point offers exciting opportunities for in-home use and wide deployment with examiners and families • Challenges with respect to stabilization for viewing/coding • Offers the examiner’s view at any time (both a positive and negative)

  2. Kinect vs. HD Video • Multiple Kinects • Positives: • Inexpensive (~5-10K for system with Kinects, PCs, and 4 Kinects) • Gives RGB + depth • Body pose estimates (in side views) • Negatives: • Overlap between Kinect views yields errors in depth streams • Each Kinect intermittently drops video frames at different times • Capture is asynchronous, which is challenging for multi-view analysis • High-res video capture (using Camera-Link) • Positives: • high-definition, high optical quality • Synchronized at time of capture • Negatives: • Expensive (~$50K for system with capture equip, PC, and 4 cameras) • Does not include depth sensing

  3. Workflow • Where in the workflow does synchronization of streams occur? • What method(s) will be used for synchronization? • Is synchronization needed?
