摘要能源是国民经济的基础，在今后相当长的时间内化石燃料的燃烧仍是获取动力的主要途径。显然,通过燃烧诊断实验对燃烧流场的各关键物理参量（温度、压强、流速和组份等）进行检测，获得其三维空间分布是进行燃烧研究的必不可少的重要手段。发射层析技术（Emission Computerized Tomography, ECT）以燃烧场中火焰的多方向光辐射为投影数据，通过CT重建获得到燃烧场的三维空间物理参量分布，如温度分布、火焰结构等。64386

本课题针对多方向的ECT投影数据提取问题，通过编程实现了多方向的相机采集与控制，并对相机聚焦判断算法，Harris角点检测技术进行了研究。在此基础之上，用所编写的程序对火焰场进行了多方向采集试验，为进一步的ECT多方向标定研究提供技术基础。

Title  Multiple direction projection based on ECT calibration  technology research 

Abstract Energy is the foundation of the national economy, the burning of fossil fuels in a long time in the future is still the main way to gain power. Obviously, through the combustion diagnosis experiment of combustion flow field of the key physical parameters (temperature, pressure, flow rate and components, etc.) for testing, to obtain its 3 d spatial distribution is the indispensable important means of combustion research. Emission Tomography technique (Emission Computerized Tomography, ECT) with many direction of flame in the optical radiation as the projection data, obtained from CT reconstruction to the combustion field distribution of the three-dimensional space of physical parameters, such as temperature distribution and flame structure. 

This topic for more direction projection data extraction problem of ECT, through the programming to realize the direction of camera collection and control, and the camera is focused on the judgment algorithm, Harris corner detection technology is studied. On this basis, with a written procedure for fire field acquisition experiment, has carried on the multiple directions for further ECT direction calibration study provides technical basis.
