An Affordable Temporal Calibration Method for Common Video Camera

Article Preview

Abstract:

The temporal synchronization between video capture and sensor data acquisition are provided by most of advanced data gathering systems using dedicated (and expensive) hardware. This paper raises the question that one could obtain accurate temporal assessment with a normal commercial video camera. With the help of an affordable ATmega328 microcontroller enabled board – for real time programming, and an inexpensive LED based circuit together with some image recognition software an affordable temporal calibration method was proposed that address two of the issues concerning timing of video capture: the real time for image capture and usage of external recorded timers for synchronization between various acquisition systems.
