基于S12单片机的机器视觉系统设计与实现

his paper introduces a set of implementation and design of computer vision system to achieve the requirement of the National SmartCar Competition. The system uses S12 microcontroller as the main processing chip, and adopts CMOS camera as image acquisition unit to achieve a MCU-based image acquisition, image processing, track recognition, and intelligent decision-making functions. The system uses a brief but very effective and efficient algorithm for track detection, combined with the pre-decision method to extract useful information that could be used to control the movement of smart car. Thousands of debugging and testing confirme that the system can complete the task of tracing and predetecting of the track, and control the cart moving fast and accuratly.
