Video Integrations

Why?

- Ease marker identification- Documentation- Recording/analysis of high speed video:

Gain more insight into movements

Alternatives

• External video cameras

– Webcam– HDMI via Blackmagic– Import video file

• Qualisys video cameras

– Oqus 510+ and Oqus310+– Oqus 210c– Miqus Video Mono

Choosing video source

Let the requirements decide:

• Image Quality (Resolution, Color/Monochrome)• Frame rate (normal or high speed)• Recording of sound for documentation• Synchronization with mocap data• Calibrated video for 3D overlay of mocap data

Documentation purposes: webcam or HDMI sufficientSynchronization, 3D overlay and high speed video: Qualisys video

Webcam

• Typically 1080p/30fps• Not possible to synchronize• Not possible to calibrate• Must support Microsoft DirectShow API

HDMI via Blackmagic Designs card

• DeckLink Mini Recorder– Internal PCIe interface– HDMI/SDI input– Supports up to 1080p/30fps– Sound capturing

• Intensity Pro 4K– Internal PCIe interface– HDMI/Component/S-Video/Composite input– Supports up to 2160p/30fps and 1080p/60fps– Sound capturing– Analog breakout cable

One camera per cardData is uncompressed, use compression in QTM

Oqus/Miqus Video Comparison

• asdfasdf

Calibrated Video

• Let QTM know where camera is located inthe measurement volume

• Enables video overlay• Flash only used during calibration

Oqus Video 210c

• Easy integration• 1080p/24fps• MJPEG Compression• Synchronized capture• Calibrated capture• Color sensor• Connected in the same daisy chain as

the motion capture cameras• Supported in Oqus systems• 1.125 GB buffer for HS video

~580 frames 1080p– Use QTM video compression

Miqus Video Mono

• Easy integration• 1080p/85fps, 720p/150fps• MJPEG Compression• Synchronized capture• Calibrated capture• Connected in the same daisy chain as

the motion capture cameras• Monochrome, approx 1 EV higher sensitivity• Supported in Miqus systems• Visible light flash, only used during calibration• No buffer

Oqus 510+/310+

• Regular mocap camera with buffer and possibility to remove IR-filter• Monochrome sensor• Frame rate same as marker• Only buffered video, no streaming

• Oqus 510+– 2048x2048 180 fps

• Oqus 310+– 1280x1024 500 fps

Demos

• Webcam– Video offset

• Blackmagic Design Intensity Pro 4K– Compression

• Oqus 210c– High speed Video

• Miqus Video Mono– 3D Overlay
