    Abstract: 本研究使用單晶片電腦RaspberryPi 搭載單目鏡頭作為機器視覺系
    統,經由UART 將控制所需之回授訊號傳輸至車體控制系統之微處理器
    Arduino 控制自走車。機器視覺系統方面利用二值化、Canny 邊緣檢測、
    作為車體控制所需之參數。車體控制系統方面利用Arduino 接收之訊號
    控制鏡頭轉動,並使用PID、PI 控制法輸出PWM 訊號控制馬達實現自
    走車倒車入庫。;This research uses a singlechip
    microcomputer RaspberryPi equipped
    with a monocular len as a machine vision system, and transmits the
    values required for control via UART to the microprocessor Arduino, serving
    as a vehicle body control system, to control the selfguiding
    The machine vision system uses image processing techniques such as
    binarization, Canny edge detection, closed operation, and contour detection
    to determine whether the camera captures a parking grid image,
    and uses camera calibration to obtain the internal and external parameters
    of the monocular camera, thereby establish the correspondence between
    the threedimensional
    world coordinates and the twodimensional
    pixel coordinates, After calculation, the distance between the camera,
    the parking space and the yaw angle are obtained as parameters required
    for vehicle body control. In the body control system, the signal
    received by the Arduino is used to control the lens rotation, and the PID
    and PI control methods are used to output PWM signals to control the
    motor to realize selfguiding
    vehicle backward parking.
