The project is concerned with the development of algorithms for the creation of photo-realistic 3D virtual environments, overcoming problems in mosaicing, colour and lighting changes, correspondence search speed and correspondence errors due to lack of surface texture. A number of related new algorithms have been investigated for image stitching, content based colour correction and efficient 3D surface reconstruction. All of the investigations were undertaken by using multiple views from normal digital cameras, web cameras and a?one-shot? panoramic system. In the process of 3D reconstruction a new interest points based mosaicing method, a new interest points based colour correction method, a new hybrid feature and area based correspondence constraint and a new structured light based 3D reconstruction method have been investigated. The major contributions and results can be summarised as follows:? A new interest point based image stitching method has been proposed and investigated. The robustness of interest points has been tested and evaluated. Interest points have been proved robust to changes in lighting, viewpoint, rotation and scale.? A new interest point based method for colour correction has been proposed and investigated. The results of linear and linear plus affine colour transforms have proved more accurate than traditional diagonal transforms in accurately matching colours in panoramic images.? A new structured light based method for correspondence point based 3D reconstruction has been proposed and investigated. The method has been proved to increase the accuracy of the correspondence search for areas with low texture. Correspondence speed has also been increased with a new hybrid feature and area based correspondence search constraint.? Based on the investigation, a software framework has been developed for image based 3D virtual environment construction. The GUI includes abilities for importing images, colour correction, mosaicing, 3D surface reconstruction, texture recovery and visualisation.? 11 research papers have been published.

The CAPTECH'98 workshop took place at the University of Geneva on November 26–27, 1998, sponsored by FIP Working Group 5.10 (Computer Graphics and Virtual Worlds) and the Suisse Romande regional doctoral seminar in computer science. The subject of the conference was ongoing research in data capture and interpretation. The goals of capturing real world data in order to perceive, understand, and interpret them and then reacting to them in a suitable way are currently important research problems. These data can be very diverse: sounds, emotions, shapes, motions, forces, muscles, actions, etc. Once captured, they have to be treated either to make the invisible visible, or to understand a particular phenomenon so as to formulate an appropriate reaction, or to integrate various information in a new multimedia format. The conference included six sessions of presented papers and three panel discussions. Invited speakers treating various aspects of the topic were: Professor R. Earnshaw from Bradford University, Professor T. L. Kunii from Hosei University, and Professor P. Robert from EPFL. Professor K. Bauknecht, of the University of Zürich, President of IFIP, offered the welcoming address. Mr. E. Badique, project officer for the EU in Brussels, discussed recent results of the EU ACTS research program. Finally, the Geneva Computer Animation '98 Film Festival highlighted the evening of November 26.

Like the first edition, the central question this book addresses is how virtual reality can be used in the design, production and management of the built environment. The book aims to consider three key questions. What are the business drivers for the use of virtual reality? What are its limitations? How can virtual reality be implemented within organizations? Using international case studies it answers these questions whilst addressing the growth in the recent use of building information modelling (BIM) and the renewed interest in virtual reality to visualize and understand data to make decisions. With the aim of inspiring and informing future use, the authors take a fresh look at current applications in the construction sector, situating them within a broader trajectory of innovation. The new edition expands the scope to consider both immersive virtual reality as a way of bringing professionals inside a building information model, and augmented reality as a way of taking this model and related asset information out to the job-site. The updated edition also considers these technologies in the context of other developments that were in their infancy when the first edition was written – such as laser scanning, mobile technologies and big data. Virtual Reality in the Built Environment is essential reading for professionals in architecture, construction, design, surveying and engineering and students on related courses who need an understanding of BIM, CAD and virtual reality in the sector.

Panoramic image Virtual Reality (VR) is a 360 degree image which has been interpreted as a kind of VR that allows users to navigate, view, hear and have remote access to a virtual environment. Panoramic Video VR builds on this, where filming is done in the real world to create a highly dynamic and immersive environment. This is proving to be a very attractive technology and has introduced many possible applications but still present a number of challenges, considered in this research. An initial literature survey identified limitations in panoramic video to date: these were the technology (e.g. filming and stitching) and the design of effective navigation methods. In particular, there is a tendency for users to become disoriented during way-finding. In addition, an effective interface design to embed contextual information is required. The research identified the need to have a controllable test environment in order to evaluate the production of the video and the optimal way of presenting and navigating within the scene. Computer Graphics (CG) simulation scenes were developed to establish a method of capturing, editing and stitching the video under controlled conditions. In addition, a novel navigation method, named the?image channel? was proposed and integrated within this environment. This replaced hotspots: the traditional navigational jumps between locations. Initial user testing indicated that the production was appropriate and did significantly improve user perception of position and orientation over jump-based navigation. The interface design combined with the environment view alone was sufficient for users to understand their location without the need to augment the view with an on screen map. After obtaining optimal methods in building and improving the technology, the research looked for a natural, complex, and dynamic real environment for testing. The web-based virtual zoo (World Association of Zoos and Aquariums) was selected as an ideal production: It had the purpose to allow people to get close to animals in their natural habitat and created particular interest to develop a system for knowledge delivery, raising protection concerns, and entertaining visitors: all key roles of a zoo. The design method established from CG was then used to develop a film rig and production unit for filming a real animal habitat: the Formosan rock monkey in Taiwan. A web-based panoramic video of this was built and tested though user experience testing and expert interviews. The results of this were essentially identical to the testing done in the prototype environment, and validated the production. Also was successfully attracting users to the site repeatedly. The research has contributed to new knowledge in improvement to the production process, improvement to presentation and navigating within panoramic videos through the proposed Image Channel method, and has demonstrated that web-based virtual zoo can be improved to help address considerable pressure on animal extinction and animal habitat degradation that affect humans by using this technology. Further studies were addressed. The research was sponsored by Taiwan?s Government and Twycross Zoo UK was a collaborator.
