Real time autonomous target tracking systems require a delicate balance between hardware and software. This paper explains the processes used to build a real time target tracking system using two 168 MHz microcontrollers. The system is split into two components which the optical microcontroller uses a camera to capture a image frame which is stored into SRAM. The image processing software scans the frame for the target, computes the center location, and sends to offset to the flight microcontroller. The flight microcontroller uses the offset to determine the correction necessary to stay on collision course.
