Using Publicly Available Building Data to Improve 3D Map
No full textIn this paper, we address the problem of 3D Map accuracy. No
access to RTK GPS or LIDAR leads to poor accuracy of the map. High-rise
buildings cause even greater trajectory errors. We used artificial intelligence
methods to integrate publicly available building data and show that
it can improve map accuracy from monocular camera and inaccurate GPS
receiver. The main novelty is a method of building elevation detection in
sparse point cloud data. We match detected elevations with building data
and use modified bundle-adjustment algorithm to improve the map. We show
that proposed approach decreases the trajectory error
Predictive User Interface for Emerging Experiences
No full textThis research paper focuses on the use of predictive techniques
to improve interaction with user interfaces in emerging experiences such
as Virtual Reality, Augmented Reality, Metaverse, and touchless kiosks and
dashboards. We propose the concept of intelligent snapping, which uses gaze
tracking, head-pose tracking, hand tracking, as well as gesture recognition
and hand posture recognition to catch the intent of the person rather than
the actual input

‘How to preserve the historical essence through recognising and the effective use of historic urban structure?’ – A Case of Kalurghat Bridge at Chattogram
No full textHistoric structures are the tangible existence of cultural heritage modernizing urban history which makes the identity of a city. More than 100 years ago, the research interest increased in conserving architectural heritage, historical monuments and buildings, and its growing intensity of recognizing heritage-site as evidence of history. Besides, global literature could not satisfy how to recognize the local heritage and preserve its historical essence. Moreover, old urban structures have significant civic value to reuse publicly, which is not evident in developing counties. For instance, developing countries like Bangladesh have not yet explicitly prepared intense strategies to consider urban historical existence and its historical values. This research finds a Kalurghat bridge as a case which was the only transportation route between the southern region of the Chattogram division and the rest of the country around the beginning of the 19th century. Remarkably, the Bridge was used for a station of the East Bengal Regiment and documented in several valuable existences during the independence of Bangladesh in 1971. This research considers mixed-method research needs to consider which are context-based and design-based research applications. The main focus is to analyze the historical existence to recognize it as a heritage site by screening historical coding and determining the future effect of using a historic urban structure through morphological analysis. The secondary data (e.g., World heritage act and Antiquities Act of 1968) are used for comparative analysis to establish the existence of heritage sites. Primary data sources are used for understanding different stakeholders' perceptions through key informant interviews and narrative questionnaires. Findings illustrate that existing historical evidence should be documented as a heritage site, suggesting establishing a heritage-based public functional space with its cultural
distinctiveness, which would disclose the presence of historical pride
From a Historic Place to a Sharing Campus: Case Study of the Santa Teresa Campus of the University of Florence
Get PDFThe Santa Teresa Campus of the University of Florence has undergone a huge transformation from a 17th century convent, to the prison of the 19th and 20th centuries, and then to a 21st century university campus. Over four centuries, the form has evolved from closed to open. With the help of literature survey, field research and typological analysis of urban form, this paper analyzes the renovation strategies from three aspects. From the perspective of an open educational space, the case transforms the original internal communication space into an exhibition space open to the city. From the perspective of perceptible history, the case preserves the historic space structure and allows important historical elements to be easily seen and touched. From the perspective of the revival of the historic city, the case has become an important node of the revival by building connections of functions and activities with surrounding places. Finally, this paper summarizes three design strategies and four social conditions required for the transition from enclosed to shared urban form, making contributions to future practice.

A Research Study on Historical Preservation and Urban Renewal of the Bund
No full textThe Bund became the first area of urbanization in Shanghai in 1843. After experiencing the golden construction era in the 1930s, it formed a unique urban form of ‘high-density enclosed blocks’. In recent years, with the focus of Shanghai's urban development shifting to urban renewal, the Bund area is also gradually entering a new urban renewal cycle, facing challenges for space expansion and functional improvement, and facing the problem of mutual restriction between historical preservation and spatial growth. Therefore, in the renewal process of the Bund area, it is necessary not only to meet the spatial growth brought by the changing functions, but also to maintain its unique historical urban form and morphological characteristics. It is urgent in this cycle to establish a more targeted and operable framework of historical preservation to balance and stabilize the impact and changes brought by the renewal and development projects in the historical area. This study will take the Bund as the research object, review the historical process of its urban form and the formation of its urban spatial morphological characteristics, take ‘block-street-building’ as the research framework, analyse its multi-level spatial morphological characteristic elements, and establish its historical protection framework in the process of urban renewal. Further, this study will take the renewal projects of three blocks in the Bund area as a case study, analysing how the historical preservation framework could play an effective role in the renewal process, so as to deal with the uncertainty of development projects in various scattered blocks, and to maintain the stability and continuity of the urban form of the Bund historical area
Pedestrian Detection with High-resolution Event Camera
No full textDespite the dynamic development of computer vision algorithms,
the implementation of perception and control systems for autonomous vehicles
such as drones and self-driving cars still poses many challenges. A video
stream captured by traditional cameras is often prone to problems such as
motion blur or degraded image quality caused due to challenging lighting
conditions. In addition, the frame rate – typically 30 or 60 frames per second
– can be a limiting factor in certain scenarios. Event cameras (DVS –
Dynamic Vision Sensor) are a potentially interesting technology to address
the above mentioned problems. In this paper, we compare two methods of
processing event data by means of deep learning for the task of pedestrian
detection. We used a representation in the form of video frames, convolutional
neural networks and asynchronous sparse convolutional neural networks.
The results obtained illustrate the potential of event cameras and
allow the evaluation of the effectiveness and efficiency of the methods used
for high-resolution (1280 x 720 pixels) footage
Transformation of urban spaces of preindustrial cities in contemporary Lodzkie Voivodeship. Heritage preservation perspectives in interdisciplinary approach
No full textThe article presents the process of formation of medieval cities in central Poland. The authors focused on the most important cities before the industrial revolution in the border of present Lodzkie Voivodeship. The development of seven cities was presented, showing the conditions and process of transformations of the urban structure in different historical epochs, leading to the formation of a complete urban plan. In the next part of the article, the authors discuss the immutability of the medieval urban plan, despite the transformations that took place in the nineteenth and twentieth centuries. The evaluation of the urban structure is presented on the example of one of the discussed cities, showing the most important elements of historical heritage, as well as the scale of the19th and 20th century interference in the historical city plan. Finally, the authors take up the issues of heritage preservation of historical urban structure and contemporary planning problems. The work is presented in six main sections: 1) background with a description of the general information about the formation of cities in the Lodzkie Voivodeship, 2) methodology with a description of the research method, 3) Historical description of the cities, 4 )Evaluation of urban structure
on an example of chosen city, 5) research results and discussion, 6) conclusions
Social determinants behind water towns in Pearl River Delta, China whose historical tissues survive the impact of industrialization: Take three towns within the Sangyuanwei world heritage irrigation structures as examples
No full textLocated in Foshan, Guangdong Province, China, which was awarded the world heritage irrigation structures in 2020, the Sangyuanwei polder embankment system has a history of more than 900 years and mainly consists of Xiqiao, Jiujiang and Longjiang three towns. Similar to other town in Pearl River Delta, these three also suffer from the onslaught of industrialization, but have maintain a relatively large number of historical tissues while keeping rapid economic development. This area is the largest and best-preserved dike-pond area in Pearl River Delta. Currently, there is considerable literature on the morphological characteristics of water towns in the agricultural era in Pearl River Delta, but little research has been done on that under the influence of industrialization. Meanwhile, most existing studies only focus on villages, with little mention of townships, which is actually an important content of urban morphology studies
