Refractive machining center positioning method and system

The invention discloses a refractive machining center positioning method and system, and the method comprises the following steps: obtaining watermark contour image information, calculating the center point of a watermark contour, the watermark contour being a contour formed by the contact of a contact lens and a cornea; the center point of the watermark contour coincides with the center point of the processing lens; the change of the watermark in the contact process of the cornea and the contact lens is collected in real time, the outline center coordinate is obtained by extracting the watermark outline and calculating, the outline center coordinate is dynamically visualized, and the spatial position and posture of a patient are finely adjusted in cooperation with a movable patient bed. A doctor is guided to achieve accurate and automatic butt joint of the machining center and the optimal refraction center, and the precision is effectively improved. 本发明公开了一种屈光加工中心定位方法及系统，包括如下步骤：获取水印轮廓图像信息，计算水印轮廓的中心点，水印轮廓为接触镜
