APLITOP MDT Point Cloud

Point cloud management

This application, as an optional MDT module, allows the user to view and process point clouds captured by LiDAR technology, scanners or photogrammetry applications.

You can manage millions of points imported from files of the most common formats. The points can be represented by natural colour, intensity or category. MDT Point Cloud also derives profiles and cross sections from a polyline or alignment, as well as digital models that can be easily exported to CAD.

Description

Point Clouds

It is possible to manage millions of points imported from files in common formats: generic scanner files and LIDAR standard format files.

This application allows the users to import several point clouds separately or import them to a single file, with all information stored in each point.

 

Point Visualization

Visualization can be set up in orthographic or perspective mode, and it has tools for zooming, panning and changing viewpoints, etc.

Points can be viewed in natural colour, intensity or category. The percentage of points to be displayed and the pixel size of the points can be controlled. The point cloud can also be viewed in stereoscopic mode with active and passive systems.

On opening a drawing with TcpMDT, the users can control the visibility of each layer.

 

Profiles

The quick profile option enables the users to get an immediate view on the profile which is on a reference plane and generated from a polyline drawn on the screen. By executing the command, MDT presents profile by generating an image consisting of the projection of points selected within a distance, with real coordinates and size, which allows the user to draw it in the viewer or  on the CAD.

More accurate results can be obtained by drawing alignments or importing them from TcpMDT. Profiles and cross sections are created by alignments an can be drawn manually or directly on the CAD.

 

Digital Terrain Model

The software features severl options for selecting the points to be processed. Thus, points can be filtered in accordance with their position or category, and the boundary can be delimited by a rectangle or 3D box.

Once the points are selected, the digital model can be created. The result can be viewed on the point cloud and also be stored as a surface or mesh.

Once the terrain has been defined, contour lines can be drawn over the point cloud as well.

 

Filtered Point Clouds

The application lets the user to create new point clouds from the selected points or from all the currently visible points (neither hidden nor filtered by scan or category). Also, it allows to set the color of the points of the new point cloud based on the pixels of a set of georeferenced orthophotos).
