| 摘 要： | 良好的手术操作对象的几何模型能提高虚拟手术系统的沉浸感，为了获得逼真的股骨、胫骨和髌骨的几何模型，论文对膝关节的CT图像进行分析，根据灰度直方图选取合适的阈值进行阈值分割，并结合区域生长做进一步的处理，最后进行三维重建。结果表明建立了更精确的几何模型。

| Abstract: | Lifelike geometric models of operation objects of surgery can improve the immersion feeling of virtual surgery training system. To get the lifelike geometric models of femur, tibia and patella, the article analyze the CT images of knee, and select appropriate threshold for segmentation according to histogram of image, and use region growing segmentation for further processing. Finally, we get accurate models from 3D reconstruction based on processed images. |

| Keywords: | CT images thresholding segmentation region growing three dimensional reconstruction |
