The task remains the same which is to extract intelligent data from images and (or) point cloud data (LiDAR, DSM, point clouds) in the form of vectors and attributes for various disciplines.  VrThree (VrLiDAR) offers the ability for photogrammetry firms to utilize existing personnel and software while offering new and powerful tools for other mapping disciplines such as architecture, all types of surveying and engineering.

 

VrThree (VrLiDAR) is software that integrates point cloud data into the time tested Vr Mapping Software packages, VrOne® and VrTwo.   This package allows the display and editing of LiDAR point data in 2D and in true three-dimensional stereo.  The four configurations available in VrThree enable vector, symbol and text entities to be collected and edited using the extensive VrOne®/VrTwo mapping tools.

 

Mapping professionals now not only need the ability to collect three dimensional vector data from traditional photogrammetric sources such as aerial and close range photography, but there is also a growing demand to collect the same vector data from LiDAR in the form of points over photographic stereo images and from point clouds without any photography.  In today's market one method of data collection is no longer adequate and VrLiDAR offers several options using photography and (or) LiDAR point data, offering the user multiple choices.

​

Features Include

​

• A familiar, existing Vr Mapping interface

• Multiple, true three-dimensional working environments>

• Ability to store large amount of points along with vector data

• Point cloud and polygon editing tools

• Ability to collect and edit vector mapping data on top of the point cloud data

• Compatible with aerial and ground based mobile and static LiDAR data

• Support for over 190 existing Vr Mapping commands and applications

• Automatic Cursor Draping available in the VrThree environment

• Up to 16 LiDAR attributes per point including intensity and classification

• User defined point density, point size and decimation density

• High speed input and output to and from LAS and other data formats

• Offered as an addition to VrOne® and VrTwo

 

In addition to collecting and editing vector data, point data can be edited using VrThree (VrLiDAR).  Tools such as polygon and cursor draping, bulldozing and close delete help the user to manage and refine point data.   Now included in the VrOne®/VrTwo graphics data base is the capability to store large amounts of point cloud data.  This point data includes the attributes as defined in the ASPRS LAS data format.  Translation to and from LAS files is a fast, simple and easy process.   Other point data formats are also supported by VrThree.

 

Choices for collection and editing include many environments in VrOne® and VrTwo.   Each configuration provides the ability to collect and edit vector data and edit points.  Multiple methods may be used to complete a project.   All environments support user defined point density and size display parameters.   All existing VrOne®/VrTwo commands and applications are available in  each of the four environments.

 

2D VrThree —Very large amounts of LiDAR data can be displayed in this mode with the ability to optionally display rectified images as a backdrop.   This environment is useful for cutting and management applications.

​

Photogrammetric Stereo—Point clouds can be displayed with traditional photo based photogrammetry using VrTwo in static or roaming modes.  Any of the Vr supported camera and sensor types may be used. 

 

LiDARgrammetry—-The use of synthetic stereo imagery derived from the LiDAR point intensity data using VrTwo in static or roaming modes.

 

VrThree —- Point cloud data is displayed in true three-dimensional stereo and vectors, symbols and text may be collected on top of this data.   The data may be observed from any viewpoint, origin and scale.  Each viewing motion may be dynamically controlled by the user at any time.   Two cursor modes include Cursor Draping and Free Motion.   Cursor Draping holds the cursor to the point cloud surface in the Z axis as it is moved in the three-dimensional viewing space.
