摘　　要：定日镜是塔式太阳能热发电站的核心装置,对定日镜面形进行快速精确检测是保证电站高效运行的关键。文章基于二维条纹反射方法对定日镜面形的快速检测进行了分析研究,结合Hermite插值理论对面形进行三维重构,其研究结果将提升定日镜的面形检测效率及产品竞争力,具有很好的应用前景。Heliostat is a vital equipment of solar thermal power tower plant,a fast and accurate measurement method of heliostat shape is critical for high-efficiency operation of the plant. In this paper,the principle and method of the heliostat shape measurement based on 2D fringe reflection technology and binocular vision are deeply studied,the results are combined with the Hermite interpolation method to develop a new method for 3D shape reconstruction of the heliostat. The new method has a better application prospect to enhance the shape measurement efficiency and competitiveness of heliostat.
