Eagle-4 Digital RealTime System

Eagle-4 Digital CameraThe Eagle-4 Digital RealTime System consists of Eagle-4 Digital Cameras, the EagleHub, and EVaRT software, which can capture complex motion with extreme accuracy. Real-time capabilities allow our customers to see capture results at the same instant as the subject is performing a specific task. The Eagle-4 can be mixed with other Motion Analysis digital cameras to optimize your research lab's capabilities.

Eagle-4 Digital Camera

The Eagle-4 uses the Micron Corporation MI-MV40 sensor and operates up to 200 fps at a full resolution of 2352 x 1728 pixels, and up to 10,000 fps at reduced resolutions. For those applications that can work with the lighting limitations of external optical strobing, the new Eagle-4 camera is an excellent choice.

Portable Motion Capture SystemThe Eagle-4 Digital Cameras provide today's motion capture technicians with a tool that assures reliable and accurate data. With digital technology there is no degradation of the signal over distance, less noise, and no resampling of data on another piece of electronics.

With today's studios demanding multiple person capture within increasing volumes, the stability of the signal becomes critical. The Eagle-4 Digital Camera signal goes directly to the tracking computer via an Ethernet connection. The signal processing is embedded in the camera. This streamlined system of motion capture from camera to computer means less hardware and less potential for equipment problems. The FPGA (field programmable field array) built into the Eagle-4 is software and firmware upgradeable via the Internet - you don't even have to take the cameras down! Motion Analysis was the first company to manufacture digital cameras for motion tracking - the Eagle Digital Camera was introduced at SIGGRAPH 2001. Thousands of our digital cameras are currently in service.

The Eagle-4 Digital Camera has a larger sensor area than standard video cameras. The corresponding use of a high quality 35mm lens allows for the sweet spot of the lens to map over this larger image sensor area, resulting in greater lens and system accuracy.

  • Calibration: The Key to Real Time

    Motion Analysis uses a dynamic linearization technique which is the only technique currently available capable of producing precise and accurate calibration. First, a small four-point calibration device is used for defining the XYZ axes. A 500mm wand (for large capture volumes) or a 150mm wand (for small capture volumes) is then used for establishing camera linearization parameters. If the camera lenses are changed, recalibration takes mere moments as compared to the cumbersome, time consuming grid technique used by other motion capture systems.

    EagleHub EagleHub

    The EagleHub consists of multi-port Ethernet switch (100 Mbps) and provides power for the cameras. A single Ethernet Cat 5 Cable is used for all signals and power between the camera and the EagleHub.

    Integration

  • Fully compatible with EVaRT software
  • Standard TCP/IP Protocol
  • 128 channels of synchronized 16-bit analog data acquisition (forceplate and EMG data)
  • Exportable to all major animation software packages
  • EVaRT

    Camera Rays EVa Real-Time Software (EVaRT) provides a user with a simple and powerful interface. Under a single software environment you can set up, calibrate, capture motion in real-time, capture motion for post processing, edit and save data in the format of your choice.

    A dual monitor option provides the motion capture technician with a full view of the active capture display and graphic panels on one monitor while viewing application forms and panels on another monitor.

    Simultaneous Display of Graphical Panels

    Golf Swing in EVaRT The Eagle-4 Digital RealTime System provides simultaneous viewing of up to four different panels:

  • 3D Display- different views and angles are possible
  • 2D Display- digital grayscale and threshold images
  • Color Video Display (avi)
  • XYZ Graphs
  • Analog Graphs
  • HTR Graphs
  • Simple and Customizable User Interface

  • Post processing provides one stroke hot keys for power users
  • "Hot keys" are customizable- define your own system for processing actions
  • Preferences for features such as initial monitor display, init poses, etc., can be named to an .ini file so that multiple system users are always assured of their customized configurations at login
