The following thesis presents the system requirements, design methodology, final hardware design and system integration of a custom digital camera for high-speed pharmaceutical capsule inspections.
The primary goals of the camera design were to minimize the cost of the device and to have a flexible design that could be easily upgraded in the future. For this application, a 3.1 mega pixel CMOS image sensor was used with a USB 2.0 interface. In addition, the custom camera can pre-process image data in an embedded, reconfigurable real-time image processor implemented in a FPGA. All data processing in the camera occurs with only buffering four rows of an image, eliminating the need for RAM on the device and lowering the overall cost.
The final design was manufactured and implemented into a complete inspection system which used 16 of these cameras to inspect up to 60 000 capsules per second.
