However, the traditional linear track GBSAR can only obtain two-dimensional (2D) images, and cannot obtain three-dimensional (3D) information of the target. Therefore, the development of GBSAR system with 3D imaging capability has become a new research hotspot. The circular scanning GBSAR studied in this paper is a new GBSAR mode with 3D imaging capability, and the data are obtained by rotating around the center of the circle on the vertical plane. However, due to the observation geometry of the circular scanning curve, there are a large number of sidelobes in the 3D image which leads to the problem of unable to accurately extract the point cloud. This paper first introduces NCUT self-developed circular scanning GBSAR, and then proposes a 3D point cloud extraction method based on constant false alarm rate (CFAR) algorithm. The feasibility of this method is verified by real data experiments.","PeriodicalId":329327,"journal":{"name":"2022 IEEE 5th International Conference on Computer and Communication Engineering Technology (CCET)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122639664","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}

In this work, we propose a novel streaming media architecture over 5G network with intelligent edge for differentiated QoS requirements. Our proposed design spans a modular surveillance system architecture including the point-to-multipoint MEC gateway (MEC-GW), cloud media server, 5G network. The proposed system leverages the local data acquired at the edge GW to control multipoint video streams access in synergic optimization way, and alleviate traffic congestion near a specific base station (BS). MEC-GW schedulers with advanced adapter properties can adjust the priority state for differentiated QoS requirements and improve the efficiency in the 5G access network. Moreover, the joint 5G MEC-GWs deployment and resource allocation optimization strategy was formulated to maximize system energy efficiency (EE) taking stringent bandwidth and Qos constraints into account. By introducing Charnes-Cooper transform, a non-convex relaxation optimization is proposed to obtain the optimal solution. Real measurement and simulation results show that proposed strategy is scalable and robust, and also offer supplementary and energy-efficient room for improvement with respect to existing approaches.","PeriodicalId":329327,"journal":{"name":"2022 IEEE 5th International Conference on Computer and Communication Engineering Technology (CCET)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113935327","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}

In order to uniquely identify items, many different identification coding schemes have been designed and proposed. However, most of them have been difficult to satisfy the requirements of security, storage, and efficiency. Blockchain can provide a decentralized storage method to release the impact of security. Therefore, this paper proposed a trust blockchain-based Identifier (BID) uplink method. Frist, BID code scheme is given to realize unique identification. Second, BID document is designed to store recognizable digital object data on blockchain. Third, BID document resolution method is proposed to obtain BID document from blockchain.

A-pillar blind spots elimination can make for safer driving. Therefore, this paper proposes an algorithm that utilizes a screen mounted on the A-pillar to display its blind spots in real time and uses a wide-angle camera to capture a panoramic view outside the car. We use a binocular vision system detecting facial features to calculate the driver’s head pose and the 3D coordinates of the pupil center. After obtaining the pupil centers and coordinates of the four corners of the A-pillar display screen, the blind spot can be calculated through the angular relationship between the driver’s line of sight and the outside wide-angle camera’s angle of view. Considering the possibility that the pupil center detection may fail when the driver is not looking at the A-pillar, we propose a compensation method to indirectly calculate the pupil center by using the camera above the driver’s head. We carried out a simulation experiment using a display screen replacing the A-pillar, which showed that our algorithm could display the blind spots occluded by the display screen well.","PeriodicalId":329327,"journal":{"name":"2022 IEEE 5th International Conference on Computer and Communication Engineering Technology (CCET)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125408130","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}
