| The system architecture, in the same way as the equipment does, is divided into two categories: external and internal. | |||||
|
External Architecture The adjacent figure shows the external architecture of the system. An optical camera is used for image capture, which is built into a servo motor. The latter allows a two-dimensional (2D) movement of the servo motor-camera system. As shown in the figure, the camera and the servo motor communicate with a personal computer (PC) via Ethernet (IEEE 802.3) (black channel) and RS-232 (blue channel) respectively. Additionally, a joystick is connected via USB (brown wire). |

Internal Architecture Internally, as shown in the adjacent figure, there are two subsystems at software level. The first one implements the detection and recognition. Initially, using the Motion Detection Filter (MDF), the moving objects are detected. Then, they pass through the Recognition Filter, which consists of the Target VeRification Filter (TVRF) and the Target ValiDation Filter (TVDF). There, they are checked for their morphological validity, confirmed as targets based on their shape, color and movement, while they are constantly subject to scrutiny. The second subsystem, which implements the servo motor control, is fed with data from the first subsystem (position, target speed, etc.). Initially, these data are processed by the Servo Speed Controller (SSC). The Target Position Filter (TPS) is simultaneously activated in order to reject false positions. The "filtered" data are passed to the Target Position Predictor (TPP). Finally, the Servo Movement Controller (SMC) is activated. |
