This framework seamlessly integrates scheduling and motion\u0000planning processes to ensure the effective operation of Cooperative Autonomous\u0000Vehicles (CAVs). The spatial relationship between CAVs and passenger requests\u0000is abstracted into a Bird's-Eye View (BEV) to fully exploit the potential of\u0000the LMM. Besides, trajectories are cautiously refined for each CAV while\u0000ensuring collision avoidance through safety constraints. A decentralized\u0000optimization strategy, facilitated by the Alternating Direction Method of\u0000Multipliers (ADMM) within the LMM framework, is proposed to drive the graph\u0000evolution of CAVs. Simulation results demonstrate the pivotal role and\u0000significant impact of LMM in optimizing CAV scheduling and enhancing\u0000decentralized cooperative optimization process for each vehicle.

Augmented reality (AR) offers\u0000a promising solution to overcome this challenge. Numerous studies have shown\u0000that combining learning-based and geometric methods can achieve accurate\u0000preoperative and intraoperative data registration. This work proposes a\u0000real-time monocular 3D tracking algorithm for post-registration tasks. The\u0000ORB-SLAM2 framework is adopted and modified for prior-based 3D tracking. The\u0000primitive 3D shape is used for fast initialization of the monocular SLAM. A\u0000pseudo-segmentation strategy is employed to separate the target organ from the\u0000background for tracking purposes, and the geometric prior of the 3D shape is\u0000incorporated as an additional constraint in the pose graph. Experiments from\u0000in-vivo and ex-vivo tests demonstrate that the proposed 3D tracking system\u0000provides robust 3D tracking and effectively handles typical challenges such as\u0000fast motion, out-of-field-of-view scenarios, partial visibility, and\u0000\"organ-background\" relative motion.","PeriodicalId":501031,"journal":{"name":"arXiv - CS - Robotics","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266860","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}

While such systems are still the mainstream in underwater and\u0000pipe inspection settings, the vulnerability to noise reduced, over time, their\u0000general widespread usage in favour of other modalities(textit{e.g.}, cameras,\u0000lidars), whose technologies were encountering, instead, extraordinary\u0000advancements. Nevertheless, mapping physical environments using acoustic\u0000signals and echolocation can bring significant benefits to robot navigation in\u0000adverse scenarios, thanks to their complementary characteristics compared to\u0000other sensors. Cameras and lidars, indeed, struggle in harsh weather\u0000conditions, when dealing with lack of illumination, or with non-reflective\u0000walls. Yet, for acoustic sensors to be able to generate accurate maps, noise\u0000has to be properly and effectively handled. Traditional signal processing\u0000techniques are not always a solution in those cases. In this paper, we propose\u0000a framework where machine learning is exploited to aid more traditional signal\u0000processing methods to cope with background noise, by removing outliers and\u0000artefacts from the generated maps using acoustic sensors. Our goal is to\u0000demonstrate that the performance of traditional echolocation mapping techniques\u0000can be greatly enhanced, even in particularly noisy conditions, facilitating\u0000the employment of acoustic sensors in state-of-the-art multi-modal robot\u0000navigation systems.
