Abstract

本实用新型涉及一种沉浸式球幕影院系统,包括一块半球屏幕、高清投影机阵列以及观影平台;所述高清投影机阵列包括5台投影机,其中4台投影机安装在球冠边缘竖直和横向方向的两个对称位置,安装倾斜角度约30度,分别对应半球屏幕的上、下、左、右四个位置,另一台投影仪安装在半球屏幕下方的投影仪的斜上方,单台投影机分辨率1920*1200,通过5台投影机拼接后球幕分辨率可达3072*3072;所述观影平台为升降式平台;本实用新型通过5台摄影机实现对球幕的全覆盖,不需要实用4K级别的投影机,减少了图形运算处理器的开支,降低成本。

Description

一种沉浸式球幕影院系统
技术领域
本实用新型涉及一种沉浸式球幕影院系统。
背景技术
在球幕影院系统中,通常有以下几种摄像机融合方案:1.双4K投影机方案,在这种方案中,投影机需要确定一个优化的安装角度,且需要给投影机配置一个特质的天幕广角镜,以达到双投影机覆盖球幕的效果,其缺点是每一台4K投影机需要通过4台图像生成计算机来进行图形运算显示,两组共需8台,4台计算机均需要严格的帧同步硬件机制,硬件造价高;2.单台4K投影机方案,一台4K投影机安装在平台下方,倾斜8度;投影机不在球幕的水平中心位置,导致投影影像存在明显变形;投影机往复运动,对于投影机的对焦有着严重的影响;容易导致投射的影像聚焦不准,出现模糊情况;同时投影机灯泡的使用寿命有着严重影响,而且容易出现爆灯的情况。
发明内容
本实用新型的目的在于克服上述的不足,提供一种沉浸式球幕影院系统,通过5台摄影机实现对球幕的全覆盖,不需要实用4K级别的投影机,减少了图形运算处理器的开支,降低成本。
实现上述目的的技术措施:
一种沉浸式球幕影院系统,包括一块半球屏幕、高清投影机阵列以及观影平台;所述高清投影机阵列包括5台投影机,其中4台投影机安装在球冠边缘竖直和横向方向的两个对称位置,安装倾斜角度约30度,分别对应半球屏幕的上、下、左、右四个位置,另一台投影仪安装在半球屏幕下方的投影仪的斜上方,单台投影机分辨率1920*1200,通过5台投影机拼接后球幕分辨率可达3072*3072;所述观影平台为升降式平台。
进一步的,所述观影平台包括若干液压伸缩立臂,所述液压伸缩立臂底部设有基座,所述液压伸缩立臂通过输油管路连接有液压驱动装置,相邻两所述液压伸缩立臂之间连接有加强杆,相邻两所述液压伸缩立臂顶部连接有台架。
进一步的,所述高清投影机阵列连接一台Quadro Plex工作站。
进一步的,所述投影机亮度8500流明,对比度10000∶1。
本实用新型的有益效果:通过5台摄影机实现对球幕的全覆盖,不需要实用4K级别的投影机,减少了图形运算处理器的开支,降低成本。
附图说明
图1为本实用新型的投影仪安装示意图;
图2为本实用新型的投影仪后部观测安装示意图。
具体实施方式
下面结合附图对本实用新型的优选实施例进行详细阐述,以使本实用新型的优点和特征能更易于被本领域技术人员理解,从而对本实用新型的保护范围做出更为清楚明确的界定。
如图1和图2所示,包括一块半球屏幕1、高清投影机阵列以及观影平台3;所述高清投影机阵列包括5台投影机2,其中4台投影机2安装在球冠边缘竖直和横向方向的两个对称位置,安装倾斜角度约30度,分别对应半球屏幕1的上、下、左、右四个位置,另一台投影仪安装在半球屏幕1下方的投影仪的斜上方,单台投影机分辨率1920*1200,通过5台投影机拼接后球幕分辨率可达3072*3072。
其中,所述观影平台3包括若干液压伸缩立臂,所述液压伸缩立臂底部设有基座,所述液压伸缩立臂通过输油管路连接有液压驱动装置,相邻两所述液压伸缩立臂之间连接有加强杆,相邻两所述液压伸缩立臂顶部连接有台架;
对于方案中采用的高清投影机阵列连接一台Quadro Plex工作站;作为优选投影机亮度8500流明,对比度10000∶1。
以上实施例,只是本实用新型较优选的具体实施方式之一,本领域的技术人员在本实用新型的方案范围内的通常变化和替换都应包含在本实用新型的保护范围内。
