英文摘要： Heliostat has been the core equipment of solar thermal power tower plant, a fast and accurate measurement method of heliostat shape is critical to guarantee high-efficiency operation of the plant. In this project, the principle and method of the heliostat shape measurement based on fringe reflection technology and binocular vision will be deeply studied, content of this research are given: (1) The shape measurement method of heliostat based on combined orthogonal fringe reflection is proposed; (2) The fast and precise calibration method and algorithm of this measurement system will be proposed in detail; (3) The shape surface of large stitched heliostat is reconstructed based on measured multi-view gradient data. This project mainly discusses from four aspects as proposing the combined orthogonal fringe reflection method, presenting calibration method 3D shape reconstruction and matching corresponding data. The research of this project would provide theoretical basis and technology support for the shape measurement of heliostat, the result having a better application prospect will enhance the shape measurement efficiency and competitiveness of heliostat.
