PointCloudScene

 

What is it? Who is it for?

PointCloudScene is your best choice as a software solution for sophisticated point-cloud analysis and visualization from laser scans.  It operates completely independently as a standalone software on your windows workstation without the need of any CAD or GIS platform.  The program is mostly geared towards professionals within the fields of  civil-engineering, architecture and utilities, but also urban planners, GIS experts, and any other professionals handling or managing spatial information combined with point cloud information from laser scans will greatly benefit from implementing the functionality of PointCloudScene for their daily work tasks. 

 

The core idea is to provide a slim solution for professionals who want to extract topography and models from point clouds, calibrated images and related data into a CAD or GIS format with the same accuracy obtained by traditional time consuming methods of field survey, but who do not require the full scale and cost of an underlying CAD or GIS platform for each of their workstations.

 

 

Functionality:

Read in raw-data from laser-scans such as Lidar Aerial Survey data (LAS) or other point formats from laser scans (ASCII, PTS) and evaluate it in multiple views (plane, 3D, true stereoscopic). Orthophotos and design information from other geospatial data sources (DXF, SHAPE) can be added to the scene and elevation sensitive point colouring tools, RGB colouring and the option of viewing panorama images within the 3D scene  enhance raw-data evaluation and feature identification.  Fiter planes allow the selection of specific point-cloud sections for swift feature extraction such as edges or walls of buildings, in particular for aligned building blocks, at the same time minimizing the risk of accidentally picking up distant points from the background.  Selective snapping tools (even snapping directly to the filter planes is possible!)  enable the user to extract features interactively and to store them in existing or newly created vector themes, either in CAD (DXF) or in GIS( SHAPE) format.  In addition, templates can be defined to populate the GIS database of vector themes on the fly during vectorization.

 

 

 

 

 

Cross Section and Orthogonal View interactively

PointCloudScene can offer you a more productive digitizing work flow: you can use a cross section view and a 2D orthogonal view of the point cloud in a dynamic interactive process.  First an orthogonal clip plane is placed to crate a cross section from the cloud, clearly showing edges, corner points, curbs, etc., for example along a road profile line so that these points can be easily picked up when digitizing a highway. Then the cross section can be moved along the direction of the highway picking up more points for digitizing the linear features. The movement of the cross section can be smooth or in steps with a predefined distance.  As the features are digitized along a sequence of cross sections their correct position and alignment can be supervised in the orthogonal view and in the case of linear features predefined by digitized points, the correct point pairs can be connected, for example to form the curb lines or other linear features for corresponding sections of the road.

Stereo Digitizing

Analyzing the point cloud in stereoscopic view on a 3D display allows you to easily identify corner points and edges within the cloud structure and thereby reducing the chance of errors during the interactive feature extraction. Several digitizing tools help to fine tune the location of the measure point. An exceptional feature here is, that digitizing points can be defined even for „empty locations”, which are not given by any point within the point cloud or any other existing vector point, for example a corner point of a roof where the correct location is obvious from the point cloud structure, but no no point from the laser scan or other vector sources happens to fall into exactly that location.
