The study of movement based on video processing is a common tool in different fields. One problem in this type of installations is frame synchronization with multiple cameras. This problem can be solved with the use of cameras with genlock mechanism, but such a solution could be expensive if hardware has to be replaced, or impossible if the available cameras do not have such feature. This work shows a new method for capturing the time of each frame, which also takes into account processing unit’s speed as an extra source of measurement errors. The method uses an array of synchronized lights, which add temporal information to each frame. The system has been evaluated with several video conditions, and we show its effectiveness as well as its future use as a solution for synchronization of multiple cameras without genlock, possibly at different frame rates.
