Automatic 3-D Reconstruction of Indoor Environment With Mobile Laser Scanning Point Clouds

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
Three-dimensional (3-D) modeling of indoor environment plays an important role in various applications such as indoor navigation, Building Information Modeling (BIM), interactive visualization, etc. While automated reconstruction of 3-D models from point

A review of semi-volatile organic compounds (SVOCs) in the indoor environment: occurrence in consumer products, indoor air and dust.

Chemosphere, 2018
As many people spend a large part of their life indoors, the quality of the indoor environment is important. Data on contaminants such as flame retardants, pesticides and plasticizers are available for indoor air and dust but are scarce for consumer ...

Electronic cigarettes in the indoor environment

Reviews on Environmental Health, 2019
Abstract The use of electronic cigarettes (e-cigarettes or “vaping”) has seen an unprecedented increase worldwide. Vaping has been promoted as a beneficial smoking cessation tool and an alternative nicotine delivery device that contains no combustion by-products.

SLAM and Navigation in Indoor Environments [PDF]

, 2011
In this paper, we propose a system for wheeled robot SLAM and navigation in indoor environments. An omni-directional camera and a laser range finder are the sensors to extract the point features and the line features as the landmarks. In SLAM and self-localization while navigation, we use extended Kalman filter (EKF) to deal with the uncertainty of ...

ROUGHNESS CHARACTERIZATION OF AN INDOOR ENVIRONMENT

Image Analysis & Stereology, 2011
For a transmission at 60 GHz inside the buildings, the models of propagation currently developed do not take into account the 3D roughness of surfaces under consideration. In this paper, we deal with the evaluation of the 3D roughness of surfaces in this kind of environment.

UWB passive navigation in indoor environments [PDF]

Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies, 2011
Localization and navigation of passive target objects play a key role in many important applications. An interesting solution for passive localization and navigation is given by monostatic wireless sensor radar (WSR) networks. In this context, ultrawide band (UWB) radar provide fine delay resolution enabling high accuracy localization also in harsh ...

A classification scheme for exploring the role of wearable thermal PECS in a changing climate [PDF]

E3S Web of Conferences
Global warming due to climate change is increasingly challenging human thermal comfort in both indoor and outdoor environments. Extreme weather events, such as heatwaves and cold snaps, are expected to become more frequent and intense, posing serious ...

Airborne particles in indoor environment of homes, schools, offices and aged care facilities: The main routes of exposure.

Environment International, 2017
It has been shown that the exposure to airborne particulate matter is one of the most significant environmental risks people face. Since indoor environment is where people spend the majority of time, in order to protect against this risk, the origin of ...
