NORD LS is a Russian software product for processing and recognition of laser scanning data for automated construction of high precision 3D models of industrial enterprises and engineering structures.

NEOLANT Service is the copyright owner of the NORD LS software product.

Scope of application

 

Creation three-dimensional models of as-built objects

Creation of accurate and reliable three-dimensional models of technological objects, reflecting the current layout of equipment, pipelines, support structures, etc. It is especially important in cases when there is no or insufficient actual design documentation, as well as during development of executive documentation.

Monitoring of changes on a construction site

The technology provides control of construction processes in capital construction. By comparing the as-built model obtained by means of laser scanning with the design three-dimensional models developed in CAD systems, it is possible to trace dynamics of the construction process, compliance with the intended implementation plan, as well as discrepancies from adopted design solutions.

Creation of an information model for operation and maintenance tasks

Operation is the longest stage of the object's life cycle. In order to improve safety and efficiency of decisions made during facility operation at the indicated stage, a highly accurate and up-to-date three-dimensional model is required, which takes into account all changes in design solutions arising during construction and modernization. It is possible to achieve the required accuracy of a model by using the laser scanning technology.

Application of NORD LS will allow users to significantly reduce time and resources for creation of a three-dimensional model based on the results of laser scanning and to minimize the percentage of errors and inaccuracies associated with the use of traditional approaches to modeling.

Main product features

Point cloud editing

Provides implementation of the following modes:

  • normal mode points selection;

  • addition mode;

  • subtraction mode;

  • inversion mode;

  • color selection of points, including setting of the selection range;

  • deleting the selected points;

  • saving the edited point cloud to a file.

Working with clip volumes

Provides implementation of the following modes:

  • creating a limiting volume, cutting off all points which do not fall within the specified volume;

  • loading and adding of points to the active clip volume.

Coloring of point clouds based on set color schemes

Provides implementation of the following modes:

  • RGB (original color of the point cloud);

  • fixed color;

  • elevation;

  • intensity (if any).

Import and export to *.ptx, *.pts, *.e57, *.poct formats

Provides implementation of the following modes:

  • direct conversion to *.poct format from *.ptx, *.e57, text formats (*.pts, *.asc, *.csv, etc.);

  • reverse conversion;

  • *.poct reindexing.

  • batch conversion available.

Point cloud conversion

Provides implementation of the following modes:

  • transformation in absolute coordinates;

  • through displacement and rotation angles on each axis;

  • rotation relative to the axis by a certain angle with an offset.

  • transformation in relative coordinates.

Point cloud scans registration

Provides functionality for conversion of a coordinate system consisting of several point cloud files to a basic (base) coordinate system. For example, geodetic survey data can be used as basic coordinates.

Provides implementation of the following modes:

  • registration by three or more selected points;

  • registration based on spheres.

Point clouds preliminary preprocessing

Provides implementation of the following modes:

  • cutting: in the course of conversion, a user can set the value of a thinning filter in mm (from 0 to 100 inclusive);

  • deletion of duplicates of points during conversion;

  • deletion of "noisy" points.

Point cloud recognition  and automatic building of a geometric 3D model based on geometric primitives

Provides the following tools:

  • fitting of geometric primitives to an array of points (cylinder, sphere, torus, plane, line) with control by means of standard deviation;

  • snapping to the center line of a cylinder;

  • automatic mode for searching and putting a cylinder when the search area is specified;

  • recognition of cylindrical surfaces in the selected volume;

  • tracing the axes of a piping system in the given volume and determination of the junction points of the linear pipe segments;

  • application of the catalog of elements carried out when recognizing pipes, elbows, tees.
