多功能厅大屏幕位置问题的解决——建立人体正坐模型

Determining the Height of Large Screen through Establishing the Human Body Sitting Model

通过实际工程案例,在由平面型和阶梯型两种不同类型会场布局组成的多功能厅中,通过建模计算,对不同区域不同位置观众的遮挡程度做了定量分析,同时计算出相应的视角和仰角,依此来评估大屏幕高度下降对观看效果的影响程度。文中所采用模型尺寸及分析方法可用于类似项目的工程设计中。

In a true engineering project, a quantitative analysis is makda for the degree kept out of line of sight of the audiences, who are sitting in different position in different area in a multi-faction hill, which is mixed by the plane distribution meeting model and the ladder distribution meeting model. The angle of elevation and view is calculated in the same time. The sight＇ s degree influenced by reducing the height of the large screen is evaluated. The model size and the way of analyzing can be used in the engineering design of similar project.
