Matterport3D: Learning from RGB-D Data in Indoor Environments

Access to large, diverse RGB-D datasets is critical for training RGB-D scene understanding algorithms. However, existing datasets still cover only a limited number of views or a restricted scale of spaces. In this paper, we introduce Matterport3D, a large-scale RGB-D dataset containing 10,800 panoramic views from 194,400 RGB-D images of 90 building-scale scenes. Annotations are provided with surface reconstructions, camera poses, and 2D and 3D semantic segmentations. The precise global alignment and comprehensive, diverse panoramic set of views over entire buildings enable a variety of supervised and self-supervised computer vision tasks, including keypoint matching, view overlap prediction, normal prediction from color, semantic segmentation, and region classification

Urban Design of Bristol Waterfront, Lower Thames Street

The marketplace is going to be one of the highlights on Thames Street, serving as a destination for leisure, shopping and dining. The concept of the project is to have indoor space continue out to the water, providing an outdoor space for dining and leisure, but also giving the boardwalk a resting point. The building is planned as two floors, with the fish market and multipurpose area on the first and an eatery, sitting area, balcony and facilities on the second. The building will be made of a light metal frame with panels to enclose the space and is designed with a folded glass panel that can be opened up to the outside, yet decrease wind pressure in a storm

In the adaptive reuse of the Paisley Mill, the intent of the design was to reflect the original use and construction of the mill. Additions and modifications were minimized and struct1Jral elements were exposed. The exterior elements in the renovation replaces a portion of he original painted wood siding with glazing which provides a connection for the interior spaces to the environment. allowing t-he green wall to reflect the surrounding woodlands. The new construction mainly involves the addition of this curtain wall assembly in select bays. The glazing continues from the roof to the ground floor allowing light and views between the interior and exterior. As the original cladding is retained on the exterior, the exposed structural members increase the presence of the building\u27s original construction on the interior, reflecting t-he long history of the building. This section shows the details of these floors and connections

Urban Design of Bristol Waterfront, Lower Thames Street

Collaboration with the Town of Bristol in the fall of 2013 when students in ARCH 415, Advanced Design Studio – Urban, under the guidance of Professor Ulker Copur, studied the waterfront area along the west side of Thames Street, from State Street south to the armory in Bristol, Rhode Island, including the continuation of a public boardwalk through the area linking up with the adjacent properties. The designs created by students would be used to guide the town in developing a master plan for the area and the new Bristol Maritime Welcome Center

Im2Pano3D: Extrapolating 360 Structure and Semantics Beyond the Field of View

We present Im2Pano3D, a convolutional neural network that generates a dense prediction of 3D structure and a probability distribution of semantic labels for a full 360 panoramic view of an indoor scene when given only a partial observation (<= 50%) in the form of an RGB-D image. To make this possible, Im2Pano3D leverages strong contextual priors learned from large-scale synthetic and real-world indoor scenes. To ease the prediction of 3D structure, we propose to parameterize 3D surfaces with their plane equations and train the model to predict these parameters directly. To provide meaningful training supervision, we use multiple loss functions that consider both pixel level accuracy and global context consistency. Experiments demon- strate that Im2Pano3D is able to predict the semantics and 3D structure of the unobserved scene with more than 56% pixel accuracy and less than 0.52m average distance error, which is significantly better than alternative approaches.Comment: Video summary: https://youtu.be/Au3GmktK-S

Developing Future UK Energy Performance Standards: The St Nicholas Court project, Final Report

The St Nicholas Court Project was set up to explore the implications of an enhanced energy performance standard for new housing for the design, construction and performance of timber framed dwellings. The energy performance standard, EPS08, is modelled on proposals made by the DETR in June 2000 for a possible review of Part L of the Building Regulations in the second half of the present decade. The overall goal of the project was to support the next revision of Part L through an enhanced body of qualitative and quantitative evidence on options and impacts. The seeds of the project were contained in a report – Towards Sustainable Housing - commissioned by Joseph Rowntree Foundation at the start of the last review of this part of the Building Regulations. The project itself has been based on the St Nicholas Court Development which involves the design and construction of a group of 18 low energy and affordable dwellings on a brown field site in York (see site plan below). The research project was established in two stages. Initial funding was provided by the Joseph Rowntree Foundation in the spring of 1999. This ensured the involvement of the research team from the outset of the development process. Additional funding was provided from late 2000 by the Housing Corporation and by the DETR through the Partners in Innovation programme (responsibility for which now lies with the DTI). The research project was originally divided into five phases – project definition, design, construction, occupation, and communication and dissemination. Delays in site acquisition initially allowed the design phase to be extended, but ultimately forced the abandonment of the construction and occupation phases, and the scaling down of the communication and dissemination phase. Despite the delays, the development itself will now go ahead, with construction starting in mid-2003

Buildings in Barcelona protected from railway-induced vibrations with base isolation

This work describes two mid-height RC base isolated buildings recently erected in Barcelona. Both buildings are located near the main railway station in Barcelona (Barcelona-Sants), thus undergoing dynamic excitations due to intensive railway traffic. The base isolation system consists of spring-dashpot devices located at the ground level. The isolators were designed after the expected input according to extensive field measurements. The moderate levels of vibrations detected from numerical simulations (dynamic analyses) and from present observations confirm the efficiency of the base isolation systems.Postprint (published version

Dense Piecewise Planar RGB-D SLAM for Indoor Environments

The paper exploits weak Manhattan constraints to parse the structure of indoor environments from RGB-D video sequences in an online setting. We extend the previous approach for single view parsing of indoor scenes to video sequences and formulate the problem of recovering the floor plan of the environment as an optimal labeling problem solved using dynamic programming. The temporal continuity is enforced in a recursive setting, where labeling from previous frames is used as a prior term in the objective function. In addition to recovery of piecewise planar weak Manhattan structure of the extended environment, the orthogonality constraints are also exploited by visual odometry and pose graph optimization. This yields reliable estimates in the presence of large motions and absence of distinctive features to track. We evaluate our method on several challenging indoors sequences demonstrating accurate SLAM and dense mapping of low texture environments. On existing TUM benchmark we achieve competitive results with the alternative approaches which fail in our environments.Comment: International Conference on Intelligent Robots and Systems (IROS) 201

Riverside One, Middlesbrough

Riverside One is an apartment block in Middlesbrough built as part of the regeneration of the former industrial Middlehaven Docks. The brief for the building was to deliver a highly sustainable, landmark housing project exceeding Eco Homes ‘Excellent’, in line with ‘One Planet Living’ sustainability goals. The building addresses the following research questions: How can a memorable building challenge the flatness of generic urban planning within the framework of market driven regeneration? How can the communicative surface perform architecturally? How can environmental principles be incorporated into an art based architecture practice? The design of Riverside One was driven by contextual concerns involving detailed fieldwork and a close reading of the site to discover the narratives of place and the specifics of its history. Found models were then reworked through collagist / dada-ist methods to create a new assemblage that carried with it old associations and meanings and created new ones. Methods used to reorganise existing information into a new constellation were the appropriation of images, references, history and values; collage, juxtaposition and humour. At the same time as this visual, aesthetic research, Riverside One required considerable environmental and technical research to meet its sustainability standards. This involved participation in numerous sustainability workshops and in depth, detail design of the building’s external façade to ensure water and airtightness. Riverside One is a contentious building that has been widely disseminated and debated in the architectural and public media. This includes articles in dezeen, Building Design, Architects Journal and The Guardian. Built at a time of financial plenty and when there was a great deal of optimism about urban regeneration, it is seen as both representative of that optimism and all that was unreal about it.
