NEW Mining Features

New Features RiSCAN PRO - Terrain Filter - Breakline Detection

NEW Software RiMINING

Full Hardware Integration of External GPS Receiver - direct connection with external GPS receiver via RS232 - firmware supports GPS-data from NMEA-string

Overview

Full Integration of External GPS-Receiver

New plug on top of the scanner to feed in directly NMEA string (standard 0183) from external GPS receiver

RS232 cable from GPS to V-Line Scanner

New GPS mounting adapter to make sure that max. field of view of the scanner can be used

GSM-Modul or Radio-Modul delivers realtime kinematic data (RTK)

External GPS-Receiver

NEW Features for Firmeware

Integration of ext. GPS data in Firmeware

Interpretation of several NMEA strings

Interpretation of NMEA protocol for coordinate accuracy

Interpretation of NMEA protocol for coordinate transformation in any projection

External GPS-Receiver

NEW Features RiSCAN PRO

Terrain Filter

- filter settings

- resolution of final DEM - number of levels used for the hierarchic filter process (for each iteration the value of grid size is doubled) - tolerance-factor multiplied by grid-size, returns tolerance value above/below calculated robust plane of actual grid-cell - percentile defines how the representative cell-value for each iteration is calculated - max. slope angle for data processing - tolerance value for last iteration

New Features RiSCAN PRO


Terrain Filter

- filter settings

Level 1 = 1m Level 2 = 2m

Level 3 = 4m Level 4 = 8m



Terrain Filter

- filter settings



Terrain Filter

- filter settings

To filter objects, below of which are few or no terrain points, a second filter step is performed. The second filter step should be performed in cases where the usage of a single tolerance factor does not provide a satisfying classification result.



Terrain Filter

- filter settings

To filter a number of measurements below the real surface, this option should be activated. Such measurements occur mainly, when scanning on water-surfaces. The laser is reflected on the water-surface and detects objects of longer distance, but underneath the real surface.



- to remove vegetation

- to remove mining objects

- to remove measurements underneath the surface

Terrain Filter



Breaklines

- automatic extraction and classification (toe/crest)

- manual editing tool with profile-view of breakline/pointcloud


NEW Software RiMINING

Workflow Automatisation

Automatic Data Registration

Advanced Filter Algorithms

Feature Extraction (Contours, Profiles, Breaklines)

Volume Calculation, Surface Comparison

Various Mining Software Exchange Formats

Full Compatibility with RiSCAN PRO

Keynotes

New Software RiMINING

Full Compatibility between the Software Packages


Open an existing RiMINING / RiSCAN PRO Project

Import Stand Alone Acquired Scan Data (*.riproject)


Full Automatisation of Registration by MSA

Extraction of plane patches

MSA 1st run

HTML-Report of Result

MSA 2nd run


Filter Data to Get One Common Point Cloud

octree / 2.5d raster - simplified versions

result: - polydata-object - auto-generated 3d-view

use selection tools to remove outside data


Terrain Filter to Remove Mining-Objects

use pre-defined settings for mining-objects

mining-objects are selected

delete mining-objects


Automatic Breakline Extraction Tool

use pre-defined or manual settings for breakline-extraction

breaklines are classified in toe- and crest-lines

breaklines can be edited manually

breaklines combined with pointcloud


Simplified Meshing and Smoothing/Decimating of Data

plane triangulation method max. triangle edge length defines size of data-gaps to be closed

number of iterations and relaxation factor defines the smoothing-level. decimation factor defines the level of data-reduction. Breaklines are not affected!!


Feature Extraction

contour-lines Orientation along z-axis of mining-coordinate system

profiles two parallel planes are created within the 3d view


Cut- and Fill-Volume Calculation between two Surfaces

two surfaces and a boundary polyline must be available

differences between two surfaces can be visualized


Exchange - Data Import / Export

reference data from another RiMINING project can be imported

meshes and line-objects can be exported in various formats including Surpac and Datamine
