Camera. The restricted hardware situations in the camera and 3D vision system presently used in this paper bring about a large reconstruction error. All these aspects may be enhanced by optimizing the hardware structure of 3D vision program and using far better camera gear inside the future, so as to enhance the accuracy of your reconstruction system, after which strengthen the sensible worth from the integrated SFM algorithm. In short, determined by the current outcomes, the subsequent operate should really first additional analyze the influence mechanism in the threedimensional reconstruction error, propose the error separation, and compensation procedures to enhance the measurement accuracy. Secondly, the hardware gear with the detection system ought to be further improved to improve the practicability from the strategy. On this basis, the parameters on the printing approach are controlled to attain closedloop printing feedback.Author Contributions: Conceptualization, N.L., Y.Q., and Y.Z.; methodology, N.L., C.W., and Y.Q.; software, Y.Q. and C.W.; formal analysis, N.L., C.W., Y.Q., and Y.Z.; investigation, N.L., C.W., Y.Q., and Y.Z.; resources, N.L. and Y.Z.; information curation, N.L., C.W., and Y.Q.; writingoriginal draft preparation, C.W. and Y.Q.; writingreview and editing, N.L., C.W., Y.Q., and Y.Z.; project administration, N.L. and Y.Q.; funding acquisition, N.L. and Y.Z.

Furthermore, MGs may well feature various topologies or operative scenarios. These characteristics bring about main challenges in figuring out a appropriate protection coordination scheme. A brand new optimal coordination method for directional overcurrent relays (OCRs) in MGs is proposed. Within this case, a clustering of operational models is carried out by signifies of a Kmeans algorithm hybridized with the principal element evaluation (PCA) technique. The amount of clusters is limited by the amount of setting groups of commercially readily available relays. The outcomes carried out on a benchmark IEC microgrid proof the applicability and effectiveness from the proposed method.Citation: SaldarriagaZuluaga, S.D.; L ezLezama, J.M.; Mu zGaleano, N.
