Camera calibration method of parking system

The invention provides a camera calibration method of a parking system. The method comprises: S1, a shooting blind zone boundary line is drawn on a pavement according to a minimum parking space identification distance L; S2, the angle of a parking camera is adjusted to be at a predetermined angle theta; S3, a calibration grid is drawn in a preset pavement range; S4, the calibration grid is converted into an image coordinate system; and S5, a relationship between a position of a sub calibration grid unit C'mn corresponding to a sub calibration grid unit Cmn in the image coordinate system and a corresponding distance value is determined and is stored. Using the method, steps for camera calibration are simplified and the efficiency is improved. 本发明提供泊车系统摄像头标定方法，包括：S1、根据车位最小识别距离L在路面上画出拍摄盲区分界线；S2、调整泊车摄像头角度到预定角度θ；S3、在路面预设范围内画出标定网格；S4、将所述标定网格转换为图像坐标系；S5、确定所述子标定网格单元Cmn在所述图像坐标系中对应的子标定网格单元C'mn位置与对应距离值的关系，并将所述关系进行存储。本发明实现了摄像头标定步骤的简化和效率的提高。
