GPU Plugin using GPU Direct for Pattern Matching

On the top surface of the drum, a circular disc holding 4 PCBAs are rotating at the same angular velocity as the drum. A HB-25000-SB-C camera is used to capture images of the PCBA and the captured images are transferred directly to GPU memory by GPU Direct. Once the image is in GPU memory, a CUDA-based plugin executes a pattern matching test against a reference zone of a known good PCBA. A green box around the matched zone is displayed each time there is a good match.
