Cooperative consensus simultaneous localization and mapping for multi blimp system_Herdawatie Abdul Kadir_E3_2017_MYMY
Navigasi dalam persekitaran lautan dengan sedikit ciri-ciri statik dan menggunakan dinamik air sebagai latar belakang adalah bidang yang mencabar untuk diterokai oleh sistem berbilang ejen. Ini adalah kerana wujud pengukuran yang tidak seragam di permukaan lautan kerana pengagihan ciri spatial yang kerap berubah-ubah. Oleh itu, adalah wajar untuk mereka bentuk satu rangka kerja kerjasama persetempatan dan pemetaan yang mampu untuk mengendalikan pengukuran palsu, mengurangkan ketidaktentuan persetempatan ejen dan mampu mencapai keputusan yang cepat dan baik. Objektif utama kajian ini adalah untuk mereka bentuk satu keedah kerjasama persetempatan dan pemetaan serentak untuk berbilang kapal udara yang melibatkan permukaan air yang dinamik sebagai latar belakang dan konsensus kawanan kecil sebagai kaedah keputusan kumpulan. Rangka kerja koperasi yang baru bagi sistem berbilang kapal udara yang terdiri daripada tiga kapal udara dan pelampung isyarat telah dibangunkan dan direka bagi tujuan ini. Algoritma persetempatan dan pemetaan serentak telah direka dengan menyatupadukan tiga kaedah iaitu Penapis Kalman Lanjutan, Pengubah Ciri Peningkatan Skala dan Petunjuk Kekuatan Isyarat Penerima bagi meningkatkan proses pengurusan data. Persepsi arah dalam kumpulan berdasarkan konsensus kawanan haiwan kecil telah digunakan dalam proses pengurusan data. Konsensus kerjasama persetempatan dan pemetaan serentak ini, didapati telah berjaya mengurangkan bilangan dan mengesan ciri-ciri yang dikehendaki dalam persekitaran air jernih dan keruh. Di samping itu, berdasarkan penandaarasan konsensus kerjasama, kaedah ini telah berjaya mencapai persetujuan yang lebih cepat sehingga 8.3% dan 42% berbanding model skala bebas dan model klemm-eguilez. Selain itu, ketepatan arah telah ditemui bertambah baik sehingga 30% dan 76% daripada model skala bebas dan model klemm-eguilez. Secara keseluruhan, pendekatan yang dicadangkan telah mencapai keputusan yang baik dan terbukti boleh dipercayai dengan ketara dan boleh dilaksanakan di dalam sistem pemantauan pemerhatian lautan. __________________________________________________________________________________ Navigation in an ocean environment with few static features and dynamic water background is an adventurous field to be explored by multi-agent system. This is because of its non-uniform availability of measurement on the ocean surface since the spatial feature distribution is greatly varied. Thus, it is desirable to design a cooperative localisation and mapping framework that is capable to handle spurious detection, reduce the localisation uncertainty of an agent and achieve fast and good decision. The main objective of this research is to design a cooperative simultaneous localisation and mapping method for multi blimp system involving the dynamic water surface as the background and small flock consensus as the group decision method. A new cooperative framework for the multi blimp system consisting of three blimps and buoys was developed and designed for this purpose. The simultaneous localisation and mapping were designed by integrating three methods which are the Extended Kalman Filter, the enhanced Scale Invariant Feature Transform and Received Signal Strength Indicator to improve the data association process. The group perception of direction based on small flock of animal consensus was taken into the data association process. It was discovered that this cooperative consensus simultaneous localisation and mapping was able to reduce the number of feature points and detect the desired features in clear and dark water environments. In addition, based on cooperative consensus benchmarking, this method was able to achieve faster consensus to up to 8.3 % and 42 % than the scale free model and klemm-eguilez model respectively. On top of these, its heading accuracy was found to be more accurate to up to 30 % and 76 % than the scale free model and klemm-eguilez model respectively. Overall, the proposed approach has achieved its prominent results and it is proven to be significantly reliable and applicable to be implemented in the ocean observation monitoring system.
