This paper establishes a three-layer centralized control architecture for transmission grid, distribution grid and local equipment and a multi-layer coordinated distributed control architecture for distribution system; exploring the "source-network-load-storage" comprehensive coordination and interaction mechanism of power distribution system; researching on the operation of equipment at the source, network, load and storage ends of the distribution network, and construct a coordinated centralized optimization model of "source-network-load-storage" and a zoned distributed optimization model based on the data-driven distribution robustness method, the CCG algorithm and ADMM algorithm are used to solve the problem effectively, and the method of this paper can realize the improvement of "source-network-load-storage" regulation ability.
Virtual-real occlusion is a key step in augmented reality systems. The traditional virtual-real occlusion method has some problems, such as low accuracy and poor adaptation to the scene. On this basis, this paper proposes a virtual real occlusion method based on monocular camera. Firstly, AKAZE algorithm was combined with Tanimoto similarity estimation to find the optimal pair of feature points, and the relative depth of feature points on adjacent frames was calculated by using the triangulation method in SFM algorithm. Then, the real depth value was obtained by combining the translation scale. Finally, the depth value of virtual and real objects was compared to realize the virtual and real occlusion of monocular camera. The experimental results show that the virtual-real occlusion based on monocular camera is realized and the occlusion accuracy is high.
