手部腕关节面数学形态表达模型的研究

An Optimal Digital Model on Representing the Surface of Hand Wrist

应用摄影测量技术研究了人的手部腕关节面形态的数学模型。首先采用三维摄影测量技术对关节接触面予以摄影 ,其次利用全数字摄影测量系统对关节接触面进行数据采集 ,最后给出了关节接触面区域的最佳数学模型。实践证明 ,该成果不仅能为手外科创伤手术提供关节面间最佳吻合部位的手术指导 。

This paper proposes an optimal mathematical model to represent the surface of hand wrist. First, three\|dimensional photogrammetry is used to take photos of the touched surface of a hand wrist. Then, a system of digital photogrammetry is taken to capture the data from the photos. Finally, the optimal mathematical model is presented to represent the touched surface of the hand wrist. The result may not only show the optimal coincidence between two wrist surfaces to the surgical of hand surgery, but also benefit the make of artificial joint.
