弧幕沙盘

弧幕数字沙盘顾名思义是通过弧形的金属投影幕与沙盘结合展示数字化的内容，普通的投影幕带来的新奇感不如弧幕数字沙盘，并且展示的画面感也没有弧幕数字沙盘那么震撼。弧幕数字沙盘运用了投影融合技术对多台投影机投射出的画面进行处理，将弧幕和物理沙盘进行双向演示，能够充分展现区位特征等。

As the name implies, the arc screen digital sand table displays the digital content through the combination of arc metal projection screen and sand table. The novelty brought by ordinary projection screen is not as good as the arc screen digital sand table, and the display image is not as shocking as the arc screen digital sand table. The arc screen digital sand table uses projection fusion technology to process the images projected by multiple projectors, and demonstrates the arc screen and physical sand table in two directions, which can fully show the location characteristics.
