Quick protocol for integrating the attribute information of unstructured point cloud data into a solar envelope simulation

This study proposes a novel method of solar geometry by considering the potential application of point cloud data combined with the simulation of solar radiation. With the support of geometric and radiometric information stored in the point cloud such as position information (XYZ) color information (RGB), and reflection intensity (I),...

Investigating Surface Fractures and Materials Behavior of Cultural Heritage Buildings Based on the Attribute Information of Point Clouds Stored in the TLS Dataset

To date, the potential development of 3D laser scanning has enabled the capture of high-quality and high-precision reality-based datasets for both research and industry. In particular, Terrestrial Laser Scanning (TLS) technology has played a key role in the documentation of cultural heritage. In the existing literature, the geometric properties...

Geometry and Stability Analysis of Caves in Bahia, Brazil

More than 30% of the world’s hydrocarbon reserves are located in carbonate reservoirs, and this percentage is likely to increase, as a result of discoveries of new giant oil fields in carbonate rocks, generically named “Pre-salt layers”. However, there are still some problems in understanding karst systems that still unresolved. The karst caves...

Making use of Point Cloud for Generating Subtractive Solar Envelopes

As a contextual and passive design strategy, solar envelopes play a great role in<br/>determining building mass based on desirable sun access during the predefined<br/>period. With the rapid evolution of digital tools, the design method of solar<br/>envelopes varies in different computational platforms. However, current<br/>approaches still lack...

Semi-automatic fold detection in geological outcrops using Laser Scanning data: Applied to a limestone-marl sequences in the Vocontian Basin, France

Geological surveying is a common practice performed by geologists nowadays. Determining layer orientation parameters and identifying folds are examples of features needed in order to create a geological map or model of the (sub) surface. Surveying is expensive and time consuming, therefore such survey is recently being investigated and...

Toward an Environmental Database: Exploring the material properties from the point cloud data of the existing environment

The utilization of point cloud as a 3D laser scanning product has reached across<br/>multi-disciplines in terms of data processing, data visualization, and data<br/>analysis. This study particularly investigates further the use of typical attributes<br/>of raw point cloud data consisting of XYZ (position information), RGB (colour<br/>information...

A vario-scale approach that improves integration of point clouds with different point densities

Point clouds are becoming one of the most common ways to represent geographical data. The scale of acquisition of point clouds is growing steadily. However, point clouds are often very large in storage size and require computationally intensive operations. The integration of point clouds nowadays still face a lot of challenges. This project...

Using a space filling curve approach for the management of dynamic point clouds

Point cloud usage has increased over the years. The development of low-cost sensors makes it now possible to acquire frequent point cloud measurements on a short time period (day, hour, second). Based on the requirements coming from the coastal monitoring domain, we have developed, implemented and benchmarked a spatio-temporal point cloud data...
