摘要
传统光学天象厅因为节目制作难度大,成本高昂,功能扩展困难等缺点逐渐被功能强大的数字天象厅取代。随着天文教育和科普的深入推广,国内对数字天象厅的需求越来越大。数字天象厅的核心是球幕投影技术。针对球幕投影技术存在的一些技术问题,如自动化程度不高,需要人工干预等,提出了面向中小型球幕天象厅易于实现的多投影自动拼接方案。对方案中的几何校正、亮度校正、颜色校正等核心功能进行了详细的论述。该方案便于操作,易于实现,对中小型球幕有良好表现,对大型球幕也有借鉴意义。
Troubled by huge cost in program making and difficulties in extending its functions, traditional planetarium has been gradually replaced by powerful digital planetarium. With the development of astronomy education and popularization of science, digital planetarium is in high demand in China. The key technique for digital planetarium is full dome projection, especially the muhi-projectors＇ projection. We present a straightforward method to increase the automation in multi-projectors calibration for small and medium size planetariums. Most effort of the method is in geometry alignment, light and color calibration. This method is easy to implement and operate for target planetariums.
