大型雕塑三维透视纠正系统的研究和开发

Research on and Development of Large Scale Sculpture 3D Perspective Correcting System

由于人眼透视非线性的事实,在对雕塑手稿进行等比例放大后均需根据所观察到的透视效果对大型雕塑进行透视纠正。原来雕塑家需对照手稿人工制作透视正确的放大雕塑,由于大型雕塑体积大,手工制作工作量大,为了减少工作量,文中研究并开发了一种雕塑透视纠正系统。在该系统中,首先读入雕塑手稿的三维扫描模型数据,为雕塑设计者可使用计算机对雕塑模型数据在虚拟环境下进行放大模拟和透视纠正,随后通过将计算机生成的模型分割后进行机械加工得到大型雕塑,从而减少了真实雕塑纠正和放大所耗费的时间。

Due to the nonlinearity of the human eye perspective,large-scale sculptures need to be corrected fluoroscopically in the proportional amplification of sculpture manuscripts based on the observed effects of the perspective. The original manuscript sculptor needed to make amplified sculptures with correct perspective manually. Due to the large size of sculptures,making sculptures manually is labor consuming. In order to reduce the workload,the paper researched and developed a sculptural perspective correction system. In this system,first the manuscript sculpture 3D scan data model is read into the system,so that designers can use the computer to amplify the analog model data and correct its perspective in a virtual environment. Then the computer-generated model is divided and mechanically processed into a large-scale sculpture,thereby reducing the time for real sculpture correction and amplification.
