摘要
介绍了交互式三维测量技术在医学图像中的应用。在平行投影透视图中,将用户指定的屏幕二维坐标点转化为需要的物体坐标系下的空间三维坐标,并用取点法实现了特征点的选取。对病人的颅面部进行实际测量,得到了较为满意的结果。
The technology of interactive 3-D measurement based on medical image is introduced here. In the parallel project scenograph, the 2-D data in the screen coordinates selected by the user are transformed into 3-D in object coordinates. We employ an recognition algorithm to extract the key points are extracted. Through the measurement to the skull of some patients, some satisfy results are obtained.
