Calibration method and system for camera of scanning translation pen

The invention provides a camera calibration method and system of a scanning translation pen, and relates to the technical field of scanning translation pens. The method comprises the following steps: starting a calibration program preset in a pen, preprocessing an acquired image, selecting a to-be-detected image, capturing boundary point coordinates of the to-be-detected image, continuously selecting a plurality of pixel points from the center point position of the to-be-detected image along the Y-axis direction and the X-axis direction respectively, and by endowing the pixel points with high values or wide values from small to large, detecting and determining coordinate data of an effective window boundary line and storing the coordinate data, thereby completing the calibration process. According to the method, after the scanning translation pen is produced, the effective window boundary line of the camera can be calibrated at a time, and the calibration process is simple and efficient. 本发明提出了一种扫描翻译笔的摄像头标定校准
