LabVIEW

The architecture is divided into two parallel execution loops, each with a specific function and a different execution priority.

1. The Producer Loop: "Acquisition" (High Priority) This loop is the data producer. Its single and most critical function is to capture frames from the webcam and pass them to the consumer loop, without interruptions and as fast as possible. WebCam.lvclass Block: This is the object or class that represents the webcam. It is configured to capture image frames and extract information such as the data cluster and the capture time (dt). RT FIFO Create: This block creates a Real-Time FIFO. A FIFO is a circular memory buffer. The RT (Real-Time) concept indicates that this buffer is optimized for real-time systems, ensuring that data writing and reading are predictable and not subject to operating system delays, for example Windows. It acts as the communication between the two loops. RT FIFO Write: This block is the motor of the producer loop. It takes the captured image frame and writes it into the FIFO buffer. The writing is a high-priority operation and is optimized to be as fast as possible. Stop Control: The loop continues to write frames until a stop condition - Stop button is triggered by the user.

2. The Consumer Loop: "Communication with GUI" (Low Priority) This loop is the data consumer and its function is to read frames from the FIFO buffer and perform other lower-priority operations, such as displaying them on the screen. RT FIFO Read: This block reads the frames that were written by the producer loop.
