采用123DCatch基于照片全自动构建人体器官三维模型

摘要

Construction of 3 D model library is the key to realizing virtual laboratory of human anatomy .Due to the complicated shape of human organs , the traditional manual modeling techniques are not suitable because they are highly specialized and need big investment and long cycle .Because of its advantages in low cost , simple operation and high fidelity , photo-based 3D modeling technique is being paid close attention to by researchers .This paper , by comparing the advantages and disadvantages of various types of modeling methods and taking Autodesk 123 D Catch for an example , introduces how to realize quick construction of a photo-based virtual laboratory 3 D model library of Human Anatomy from the application point of view regarding the basic methods , corresponding processes , operation key points , precautions and application in VRML .%三维模型库的构建是实现《人体解剖学》虚拟实验室的关键。由于人体器官形态的复杂性，传统的手工建模技术因其专业性强、投入大、周期长，难以适用。基于照片的三维建模技术，因其成本低、操作简单、逼真性高等优势，逐渐得到研究者的重视。该文在比较各类建模方法优缺点的基础上，以Autodesk 123D Catch为例，从应用的角度重点阐述了其基本方法、相应流程、操作要点、注意事项及在VRML中的应用，实现了基于照片快速构建《人体解剖学》虚拟实验室三维模型库。
