EAST可见光视频诊断的图像采集

Data acquisition of visible imaging diagnostic system on EAST

为有效解决东方超环可见光视频诊断的统一控制问题,提出一种基于东方超环总控系统控制的图像采集算法。对图像采集执行过程进行认知和分解,分析图像采集控制过程的原理,在此基础上建立图像采集软件体系结构,对图像采集的功能进行了分解,提出一种基于Hermes API开发图像采集软件的设计方法,采用模块化功能程序进行系统设计。实例验证了该软件能够为东方超环等离子体物理实验研究提供稳定可靠的可见光视频数据。

To solve the problem of the unified control of the visible imaging diagnostics on EAST effectively,an image acquisition algorithm based on the control system of EAST was presented.The process of image acquisition was recognized and decomposed,and the control principle of the image acquisition was analyzed.The image acquisition software architecture was constructed,and the functions of image acquisition were decomposed.A design method of image acquisition software based on Hermes API was proposed,and the system was designed using modular function programs.A practical application was presented to verify that the software can provide stable and reliable visible imaging data for the EAST plasma physics studies.
