However, most vSLAM algorithms are incompetent to project virtual object on a specified plane, especially when rigour precision is required. This is because they fail to distinguish the mappoints of interest from other normal ones. In this work we propose a new SLAM system which integrates target detection algorithm into conventional ORB-SLAM2 so that mappoints of interest can be regarded as variables and hence be optimized continuously. Specifically, the proposed system adds a new class member called Target in the map of ORB-SLAM2 so that the system can detect the target during operation with Oriented Fast and Rotated Brief (ORB) features and distinguish the Target Mappoints from others. Compared to conventional ORB-SLAM2, proposed system needs to take on two more tasks: management of Target Mappoints and updating the projection matrix in all three treads. In this work we use the Lena picture as the target plane we want to project visual objects on and the test results demonstrate that our system can perform projection more accurately.","PeriodicalId":163200,"journal":{"name":"2021 IEEE 3rd International Conference on Circuits and Systems (ICCS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115544935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the initial design of the filter can be completed quickly through the inductive unit and capacitor unit circuit simulation and the three-dimensional electromagnetic simulation. Secondly, through the analysis of the field distribution of the typical resonance frequency of the filter parasitic passband, it is determined that the high-frequency parasitic oscillation of the filter inductance unit is the main reason for the deterioration of the filter stopband. Therefore, based on the design idea of the asymmetric inductance unit structure, the staggered distribution characteristics of the out-of-band resonance frequency points of the filter are optimized, and the structure design of the X-band wide stopband waveguide low-pass filter is realized. Simulation and measurement results show that the filter has a passband frequency response of 9.7~11GHz, and the stopband frequency range of 11.8GHz~43GHz achieves the suppression greater than 50dB.","PeriodicalId":163200,"journal":{"name":"2021 IEEE 3rd International Conference on Circuits and Systems (ICCS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125935158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The induced electric field on the earth surface is calculated by changing coast dip angle and the surface and subsurface earth resistivity. From the results, when the resistivity of surface layer is almost the same as that of sea water, the coastal effect is not obvious, and with the increase of coast dip angle, the surface electric field in offshore area increases slightly. When the surface resistivity is larger than the seawater resistivity to a certain extent, the coastal effect will make the surface electric field in the offshore area larger than that in area away from coast, and the smaller the coast dip angle is, the more obvious this trend is. The surface induced electric field in area away from coast will not be affected by the coastal effect, so it will not be affected by the coast dip angle. The influence of subsurface resistivity on the surface electric field in both offshore area and area away from coast is the same: with the increase of subsurface resistivity, the surface induced electric field gradually decreases and finally tends to be stable. When the surface resistivity is determined, the influence of the coast dip angle on the surface electric field is small. The results of this paper can provide reference for coastal effect calculation and GIC hazard assessment during geomagnetic storms.","PeriodicalId":163200,"journal":{"name":"2021 IEEE 3rd International Conference on Circuits and Systems (ICCS)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125180939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
