An Actuator reacts to a pulse in a different way, with a TRUE pulse it switches itself ON (makes itself active), with a FALSE pulse it turns itself OFF. The output pulse width for this circuit is variable from approximately 5 to 850 nsec. A 16×2 LCD display is used for displaying the frequency count. I'll focus on face detection using OpenCV, and in the next, I'll dive into face recognition. If the camera enters a time lapse interval while camera is currently recording in motion detection mode, the time lapse image will be skipped. Default value is 600. LAB 4: PULSE SHAPING AND MATCHED FILTERING I. on mobile phone and computers with webcams. A given output laser pulse can have many returns, and they must be marked in sequence of return. This is how the the output of the 'matched filter' result will look like: The peaks are where the start of the signal was detected. Below is a screen-shot of an actual run of the code. Returns the length of the pulse in microseconds or gives up and returns 0 if no complete pulse was received within the timeout. To accomplish this, you'll want to monitor the (x, y)-coordinates of the ball.
