We also have to capture the last time-stamp when “Q” was pressed, as it will cause the program to end capturing video from camera and later generate the time data. WebMultiple view Camera calibration tool This tool allows to compute the intrinsic and extrinsic camera parameters of a set of synchronized cameras with overlapping field of view. The intrinsics estimation is based on the OpenCV's camera calibration framework and it is used on each camera separately.
To capture multiple streams with OpenCV, I recommend using threading which can improve performance by alleviating the heavy I/O operations to a separate thread.
