Simple C++ Integration

A C++ interface for development replaces the previous OptiTrack SDK’s COM interface for greater ease of integration with a variety of software languages and frameworks.

Camera Control

Extensive access to camera functions, methods, callbacks and properties for complete control of your vision system, including:

  • Video mode (object, segment, precision, raw grayscale, MJPEG)
  • Frame rate w/ frame decimation control
  • Exposure w/ automatic exposure control
  • Automatic gain control
  • Hardware masking
  • Image size windowing
  • Threshold
  • Illumination
  • Filter Switcher
  • High Power Mode (Flex 13 and V100:R2/Flex 3 only)
  • Status LED control

Object Data

2D object data for up to 512 objects in the camera’s view can be extracted for tracking and filtering purposes. Available information includes:

  • Location (weighted X,Y coordinates)
  • Area
  • Width/Height
  • Roundness
  • Ability to remove lens distortion effects

6DoF Vector Tracking

The Camera SDK includes basic vector tracking for both the TrackClip and TrackClip PRO, providing 6DoF output. Vector is a proprietary technology developed by NaturalPoint for 6DoF tracking using three markers and a single camera.

Multi-Camera Synchronization

Multiple cameras can be synchronized to fire their shutters and expose frames at the same time. Instead of fetching frames from individual cameras, groups can be created to both fetch synchronized frames and confirm that cameras within the group are properly synchronized.

Sample Applications with Source Code

Source code and documentation for sample applications are included to demonstrate best practices and provide starting points for using the SDK. Sample apps include:

  • Camera List
  • Frame Synchronization
  • Image Processing
  • MJPEG Viewer
  • Segment Mode
  • Vector Tracking
