Currently, there is a growing consensus that the use of more sustainable urban freight transportation has potential to offer major energy and efficiency benefits which can be achieved through appropriate combination cargo bikes integration drones into logistics system. This study presents results stepwise regression analysis examines role, benefits, impact electric vehicles such as e-bikes, bikes, for intermodal in five Greek cities support green paradigm. The show between routes almost...
The treatment of osseous defects around teeth is a fundamental concern within the field periodontology. Over years, method grafting has been employed to treat bone defects, underscoring necessity for custom-designed scaffolds that precisely match anatomical intricacies cavity be filled, preventing formation gaps could allow regeneration soft tissues. In order create such patient-specific scaffold (bone graft), it imperative have highly detailed 3D representation defect, so resulting aligns...
The evolution of the high-quality 3D archaeological representations from niche products to integrated online media has not yet been completed. Digital archives field often lack multimodal data interoperability, user interaction and intelligibility. A web-based cultural heritage archive that compensates for these issues is presented in this paper. multi-resolution models constitute core visualization on top which supportive documentation multimedia content are spatial logical connected. Our...
Abstract. The already arduous task of collecting, processing and managing heterogeneous cultural heritage data is getting more intense in terms indexing, interaction dissemination. This paper presents the creation a 4D web-based platform as centralized hub, moving beyond advanced photogrammetric techniques for 3D capture multi-dimensional documentation. Precise metric data, generated by combination image-based, range surveying techniques, are spatially, logically temporally correlated with...
Abstract. In the last decade 3D datasets of Cultural Heritage field have become extremely rich and high detailed due to evolution technologies they derive from. However, their online deployment, both for scientific general public purposes is usually deficient in user interaction multimedia integration. A single solution that efficiently addresses these issues presented this paper. The developed framework provides an interactive lightweight visualization high-resolution models a web browser....
This paper presents a holistic guiding methodology for the development of geospatial tool to be used documentation, planning, smart management and dissemination country’s network historic hiking trails. To deal with challenges ensure sustainability site, documentation merging authoritative crowdsourced data WebGIS-based spatial analysis is necessary. Geospatial collection should include professional field surveys, photographic video recording existing walking/hiking A geodatabase, structured...
Abstract. Cultural Heritage (CH) management software represents virtual information in various ways aiming either at usability and long-term preservation or interactivity immersiveness. A single web-based framework that couples the organization of geospatial, multimedia relational data with 4D visualization, Virtual Reality (VR) Augmented (AR) is presented this paper (https://meteora.topo.auth.gr/5dmeteora.php). It comprises 5dMeteora platform Content Management System (CMS) for uploading,...
In the context of web augmented reality (AR), 3D rendering that maintains visual quality and frame rate requirements remains a challenge. The lack dedicated efficient format often results in degraded original data compromises user experience. This paper examines integration web-streamable view-dependent representations large-sized high-resolution models AR applications. developed cross-platform prototype exploits batched multi-resolution structures Nexus.js library as lightweight tests it...
Cargo drones are a cutting-edge solution that is becoming increasingly popular as flight times extend and regulatory frameworks evolve to accommodate new delivery methods. The aim of this paper was comprehensively understand cargo drone dynamics guide their effective deployment in Greece. A 5 kg payload quadrotor with versatile loading mechanisms, including cable-suspended system an ultra-light box, manufactured tested five Greek cities. comprehensive performance evaluation analysis range,...
Abstract. Deep Learning (DL) ingrained into Mobile Augmented Reality (MAR) enables a new information-delivery paradigm. In the context of 6 DoF pose estimation, powerful DL networks could provide direct solution for AR systems. However, their concurrent operation requires significant number computations per frame and yields to both misclassifications localization errors. this paper, hybrid lightweight on 3D tracking arbitrary geometry outdoor MAR scenarios is presented. The camera...
Abstract. The mission of digital Cultural Heritage (CH) repositories goes beyond engagement and dissemination; their research data should be approached correlated spatially semantically in the service conservation accessibility. Therefore, a flexible system is needed to expand, reuse repurpose content, addressing online collaboration, real time progress ease use. Towards this direction, “METEORA” web-based platform novel holistic approach organization, management visualization 3D 2D...
Abstract. Augmented Reality (AR) is more than an added value for Cultural Heritage (CH); it vital its sustainability, promotion and dissemination, increasing accessibility in CH even during difficult periods of time, like the Covid-19 pandemic. In order to be meaningful engaging, AR application should have following characteristics: easiness use, high-quality representations compatibility. This paper presents a marker-less mobile display inspection high-resolution 3D cultural assets,...
Abstract. The recent scientific and technical developments of reverse engineering methods tools have broadened the possibilities applications in field cultural heritage conservation. In this paper, two different non-contact systems were utilized for 3D data acquisition a artefact. object interest is 17th century wooden engraved ecclesiastical sanctuary ciborium. requirement model to aid art conservators preservation material restoration small damages cracks parts, thus requiring accuracy...
Abstract. The visualization of large-sized 3D geospatial models is a graphics intensive task. With ever increasing size and complexity, more computing resources are needed to attain speed visual quality. Exploiting the parallelism multi-core performance Graphics Processing Unit (GPU), cross-platform viewer developed based on Vulkan API modern C++. proposed prototype aims at textured mesh Cultural Heritage by enabling multi-threaded rendering pipeline. workload distributed across many CPU...
Abstract. Mobile Augmented Reality (MAR) aligns toward current technological advances with more intuitive interfaces, realistic graphic content and flexible development processes. The case of overlaying precise 3D representations exploits their high penetration to induct users a world where data are perceived as real counterparts. work presented in this paper integrates web-like concepts hybrid mobile tools visualize high-quality complex geometry on the environment. implementation involves...
Mobile Augmented Reality (MAR) is designed to keep pace with high-end mobile computing and their powerful sensors. This evolution excludes users low-end devices network constraints. article presents ModAR, a hybrid Android prototype that expands the MAR experience aforementioned target group.
