Cameras used for development

OptiTrack V100R2 (USB2.0)

• Pros

  • Affordable price

  • No additional interface hardware is necessary (USB2.0 interface)

  • Embedded IR illumination (No additional IR light is necessary)

• Cons

  • Relatively slow speed (100fps)

• Note

  • Focal length of the genuine lens (f=4.5mm or 5.5mm) is too short for gaze tracking. M12-mout lens with longer focal length (e.g. 25mm) is necessary.

  • Camera should be placed near participant's face (less than 15cm-20cm from eye) to prevent bright pupil.

OptiTrack V120slim (USB2.0)

Pros

• Relatively affordable price (Although camera unit is not so expensive, IR illumination and CS-mount lens are necessary)

• No additional interface hardware is necessary (USB2.0 interface)

Cons

• IR illumination and CS-mount lens are necessary

Note

• 800nm IR pass filter option is highly recommended.

Toshiba Teli CleverDragon CSCV90BC3 (CameraLink Base configuration)

• Pros

  • Customizable camera speed

  • less expensive than ICL_B0620

• Cons

  • IR illumination and C-mount lens are necessary

  • CameraLink interface board is necessary

• Note

  • Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see Why IR illumination is necessary?).

IMPERX Bobcat ICL-B0620 (CameraLink Base configuration)

• Pros

  • High-speed image capture (260fps in default, works at 500fps or higher depending on the recorder PC)

• Cons

  • expensive

  • IR illumination and C-mount lens are necessary

  • CameraLink interface board is necessary

• Note

  • Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see Why IR illumination is necessary?).

imi tech IMB-11FT (IEEE1394a)

• Pros

  • This camera can be controlled from SimpleGazeTracker OpenCV edition. That is, this camera can be used with Win, Mac and Linux.

• Cons

  • IR illumination and CS-mount lens are necessary

  • Not so fast (up to 86Hz).

  • Some camera parameters cannot be correctly set through OpenCV.

• Note

  • Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see Why IR illumination is necessary?).

LogiCool Webcam Pro 9000 (USB2.0)

• Pros

  • This camera can be controlled from SimpleGazeTracker OpenCV edition. That is, this camera can be used with Win, Mac and Linux.

  • No additional interface is necessary.

• Cons

  • IR illumination is necessary

  • Slow (30Hz)

  • Low adjustability

  • Built-in IR cut filter should be removed.

• Note

  • Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see Why IR illumination is necessary?).

Point Grey Flea3 FL3-U3-13Y3M-C (USB3.0)

• Pros

  • High-speed image capture (150fps in default, works at approximately 490fps depending on camera mode)

  • No interface board is necessary if your PC has USB3.0 interface.

  • Price is low considering performance.

• Cons

  • Captured image is noisy compared to ICL-B0620 at high fps.

  • Camera spped is not stable at high fps.

  • IR illumination and C-mount lens are necessary

• Note

  • Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see Why IR illumination is necessary?).
