.. _cameras-develop: Cameras used for development ============================= OptiTrack V100R2 (USB2.0) ------------------------- .. figure:: cam_v100r2.jpg .. figure:: cam_v100r2lens.jpg - 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) --------------------------- .. figure:: cam_v120slim.jpg 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) ------------------------------------------------------------------- .. figure:: cam_CSCV90BC3.jpg - 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 :ref:`why-IR`). IMPERX Bobcat ICL-B0620 (CameraLink Base configuration) ------------------------------------------------------- .. figure:: cam_ICL-B0620.jpg - 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 :ref:`why-IR`). imi tech IMB-11FT (IEEE1394a) ----------------------------- .. figure:: cam_IMB-11FT.jpg - 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 :ref:`why-IR`). LogiCool Webcam Pro 9000 (USB2.0) --------------------------------- .. figure:: cam_logicool9000pro.jpg - 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. .. figure:: cam_irfilter_9000pro.png - Note * Inserting IR pass filter between the sensor and the lens would reduce measurement noise (see :ref:`why-IR`). Point Grey Flea3 FL3-U3-13Y3M-C (USB3.0) ------------------------------------------ .. figure:: cam_FL3-U3-13Y3M-C.jpg - 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 :ref:`why-IR`).
