Exploration strategies are an important ingredient for map building with mobile robots. The traditional greedy exploration strategy is not directly applicable in unbounded outdoor environments, because it decides on the robot’s actions solely based on the expected information gain and travel cost. As this value can be optimized by driving straight into unexplored space, this behavior often lead...

We describe a probabilistic framework for learning models of pedestrian trajectories in general outdoor scenes. Possible applications include simulation of motion in computer graphics, video surveillance, and architectural design and analysis. The models are based on a combination of Kalman filters and stochastic path-planning via landmarks, where the landmarks are learned from the data. A dyna...

in this research, first was identified suitable regions (considering ecological indexes) for intensive and extensive outdoor recreation and their various degrees using the usual tourism ecological model and applying gis. results showed that 297.223 hectares of park area have class 1 of extensive outdoor recreation potential, 86.465223 hectares class 2 of extensive outdoor recreation potential, ...

We describe an outdoor mobile robot navigation and localisation system based on a new visual feature detector designed for wide-angle image sequences. Wide-angle images exhibit significant radial distortion for which existing scale-space detectors such as SIFT are inappropriate. We argue that the required scale-space images can be correctly obtained through the convolution of the image, mapped ...

The research question is: “How to develop and apply acoustic artefacts and design methodologies for improving soundscapes in urban outdoor spaces?” In the project, this research question is limited to one specific type of urban outdoor space – city-park – and to two types of acoustic design artefacts. These are: I. Dynamic promotion of qualitative site specific sounds (e.g., the overall site sp...

Beautiful outdoor locations are protected by governments and have recently been shown to be associated with better health. But what makes an outdoor space beautiful? Does a beautiful outdoor location differ from an outdoor location that is simply natural? Here, we explore whether ratings of over 200 000 images of Great Britain from the online game Scenic-Or-Not, combined with hundreds of image ...

This paper describes research that investigates the application of outdoor Augmented Reality (AR) for three-dimensional graphical simulation of construction activities. The objective of the research is an AR-based platform that can be used with corresponding peripheral equipment (Head Mounted Display, GPS receiver, orientation tracker, and a portable computer) to generate a mixed view of the re...

This paper focuses on soundscape planning, or acoustic design, in the planning and management of open space in both urban and non-urban areas. It is based on notions, promoted over several decades, that the acoustic aspects of open space can, and should be, subject to design in the same way as are the visual dimensions. The current paradigm for the management of the outdoor acoustic environment...

Preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. If the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. Regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have b...
