A method for computing the displacement vector of cloud clusters in sky image

The invention discloses a method for calculating a cloud cluster displacement vector of a sky image, which obtains a plurality of combined optimization calculation models through processing a sample sky image, and calculates a new cloud cluster displacement vector of the sky image according to the combined optimization calculation models, so that more accurate cloud cluster vector calculation canbe obtained. The method for calculating the displacement vector of a cloud cluster of a sky image provided by the invention can face different motion modes of the cloud cluster and select corresponding different calculation strategies, that is, each weight of the three methods is respectively set in a combined calculation model. The method can improve the limitation of the traditional single method in the scope of application, and can be applied to most of the cloud scenarios with high robustness. 本发明公开了种天空图像云团位移矢量计算方法，通过对样本天空图像进行处理获取多个组合优化计算模型，并根据多个组合优化计算模型对新的天空图像云团位移矢量进行计算。从而可以获得更加准确的云团矢量计算。本发明提供的天空图像云团位移矢量计算方法能够面对云
