Abstract

一种摄像机基座，包括有基座与设置于基座上的光栅尺，光栅尺包括标尺光栅与光栅读数头，基座包括有设置于上部的旋转台以及设置于下部的固定座，旋转台与固定座的连接处环设有标尺光栅；固定座与标尺光栅连接，旋转台与光栅读数头连接。通过环形标尺光栅的设置，配合光栅读数头，就可以得出基座在一个环形范围内的移动位移，通过光栅尺得到的环形移动位移，就可推算出基座的转动角度，再结合当前基座所处的角度，就可以很轻易的得出基座的初始位置。

Description

一种摄像机基座
技术领域
本发明涉及基座领域，尤其是一种摄像机基座。
背景技术
摄像机基座在摄像机的拍摄过程中起到非常重要的作用，起到稳定摄像机，防止画面抖动以及长时间稳定拍摄的作用，但是现在市场上的固定座一般都是起到简单的固定支撑作用，可以实现摄像机的一定范围内移动，在长时间拍摄时，拍摄者往往会遗忘摄像机的移动过程，很难找到最初的拍摄点，为以后的记录或者画面比对造成很大的困扰。
发明内容
本使用新型主要解决的技术问题在于提供一种摄像机基座。
本发明为解决上述技术问题采用的技术方案为：
一种摄像机基座，包括有基座与设置于基座上的光栅尺，所述光栅尺包括标尺光栅与光栅读数头，所述基座包括有设置于上部的旋转台以及设置于下部的固定座，所述旋转台与固定座的连接处环设有光栅尺；
所述光栅尺包括标尺光栅与光栅读数头，所述标尺光栅设置于固定座上部，所述光栅读数头设置于旋转台下部；
所述固定座底部设置有三脚架，所述三脚架与固定座通过伸缩臂连接。所述光栅尺连接有独立电源。所述伸缩臂包括有伸缩杆与万向球，所述万向球设置于伸缩杆一端。所述伸缩杆为电动伸缩杆。所述旋转台为电动旋转台。
本发明的有益效果：
1.通过环形标尺光栅的设置，配合光栅读数头，就可以得出基座在一个环形范围内的移动位移，通过光栅尺得到的环形移动位移，就可推算出基座的转动角度，再结合当前基座所处的角度，就可以很轻易的得出基座的初始位置。
2.光栅尺的位移测量非常准确，进而通过光栅尺的位移数据推算出的移动角度也非常准确，效率非常高，而且光栅尺基本不影响基座原先的使用效率和便捷性。
附图说明
图1为本发明一种具体实施方式的结构示意图。
图2为本发明一种具体实施方式的俯视图。
图中：1为旋转台，2为固定座，3为标尺光栅，4为光栅读数头，5为伸缩臂，6为三脚架。
具体实施方式
请同时参阅图1与图2，为本发明的一种具体实施方式。
一种摄像机基座，包括有基座与设置于基座上的光栅尺，所述光栅尺包括标尺光栅与光栅读数头，所述基座包括有设置于上部的旋转台1以及设置于下部的固定座2，所述旋转台与固定座的连接处环设有光栅尺；所述光栅尺包括标尺光栅3与光栅读数头4，所述标尺光栅设置于固定座上部，所述光栅读数头设置于旋转台下部；
所述固定座底部设置有三脚架6，所述三脚架与固定座通过伸缩臂5连接。
光栅尺连接有独立电源。
伸缩臂包括有伸缩杆与万向球，所述万向球设置于伸缩杆一端。伸缩杆为电动伸缩杆。万向球为塑钢球。旋转台为电动旋转台。独立电源为锂电池。三脚架材质为高强塑料。
通过环形标尺光栅的设置，配合光栅读数头，就可以得出基座在一个环形范围内的移动位移，通过光栅尺得到的环形移动位移，就可推算出基座的转动角度，再结合当前基座所处的角度，就可以很轻易的得出基座的初始位置。
光栅尺的位移测量非常准确，进而通过光栅尺的位移数据推算出的移动角度也非常准确，效率非常高，而且光栅尺基本不影响基座原先的使用效率和便捷性。
