城市历史空间的计算机视觉模拟研究与应用——以清天安门广场为例

Study and Application of the Computer Visual Simulation of Urban Historical Space——Tian An Men Square of the Qing Dynasty

结合清天安门广场的计算机视觉模拟研究案例,初步探讨利用计算机建立数字模型来研究城市历史空间的过程与方法,及其在研究和教学中的应用。分析了计算机模拟城市历史空间在历史考证、尺寸推敲、模型更改、建模自动化、运算量控制等方面的难点,指出数字模型的建立是城市历史空间视觉模拟研究的关键。

Taking Tian An Men Square of the Qing Dynastyas an example, this paper discusses the process and method ofthe study of urban historic space by utilizing modeling building and application to researches and instruction. It pointsout that the digital model building is the key to the computersimulation study of urban historic space and there exist somecruces in the work of the textural research in history, the dimension studies, the modeling change, the modeling automation and the operand control.
