摘　　要：目的：验证牙冠外形三维光学测量系统标定实验（一）的结果。方法：用牙冠外形三维光学测量系统测量标准圆柱状石膏模型，将测量得到的位相值转成该石膏模型表面高度值。结果：得到标准圆柱状石膏模型表面实际高度图，比较准确地反映出了被测量圆柱标准试件的高度。结论：所采取标定实验简单实用。Objective: To validat the resuls from the demarcating experiments on an optical instrument for measuring toothcrown 3D shapes(One). Method: A standard column plaster cast was measured with the optical instrument for measuring toothcrown 3D shapes,then phase value of the column plaster cast was transformed to an actual value. Results: The actual height distributing maps of the standard column plaster cast surface were obtained. Conclusion: This method is brief and practical in application.
