Reflective a4tech model pk 333mb isn’t as bright as using LEDs so the camera’s infrared blocking filter may need to be removed. Camera Camera requirements Recommended cameras Compatibility list Camera requirements Webcams are the most applicable camera to use with FreeTrack as they are common and inexpensive with good PC connectivity and most known brands are suitable for optical tracking.
Manual exposure is essential for maximum stable frame rate in all a4tech model pk 333mb conditions and the ability to reliably isolate points. They typically have specifications of 30fps maximum frame rate, at least x resolution, 40 degrees field of view and have CPU usage.
Cameras with built-in infrared LEDs are well suited to reflective tracking, those that only activate in the dark can be made to stay on by covering the light sensor. Some webcams advertised with ‘night vision’ just use bright white visible LEDs that are blinding, so be sure the LEDs are actually infrared. Bluetooth adds a very small latency.
Other types of cameras may need a capture card for connection to PC. These cameras may require using VistaEnabler to disable autoexposure and shining a bright light at the camera to increase frame rate. Updated a4tech model pk 333mb Kestrel Sep.
