BlastMetriX UAV version 4.0.2

This is a service release which includes the features outlined below.

SMX MultiPhoto

BMX BlastPlanner
  • New! Display of the altitude at the borehole collar and of the floor level in the minimum burden diagram
  • New! User adjustable colour scheme for the visualization of the burden situation on the 3D model

BlastMetriX UAV version 4.0

This is a major release. The MultiPhoto component has been again revamped and improved and we integrated the referencing mechanism directly into the component. This

SMX MultiPhoto
  • New! Complete new referencing mechanism for 3D models including enhanced possibilities and instant quality feedback (replaces the use of the SMX Referencer component)
  • New! GCP constrained optimizations and referencing of 3D models
  • New! Import of GPS co-ordinates from an (ASCII) TXT file
  • New! Automatic generation of a quality report for the reconstruction (PDF)
  • New! Automatic generation of ortho-photos (PNG)
BMX BlastSiteGenerator3D
  • Improved error analysis and warnings
SMX VolumeCalculator
  • Feature enhancement in the Heap Mode – One Model (formerly Heap Mode -Reference Plane)
    • automatic positioning of bounding planes for individual heap volumes
    • boundary planes are user adjustable
  • New! Re-designed user interface
  • New! Minimum Burden mode (beta version) for automatic optimised placement of boreholes
  • New! Exportable plan views of distances between adjacent boreholes at various depths (inter-hole distances)
  • New! Move boreholes positions in respect to the profile plane
  • New! Lock subdrilling for the drill pattern, individual rows or single boreholes
  • New! Display of the reconstruction report of 3D models generated by SMX MultiPhoto v4.0
  • New! Feature: Import designed drill pattern from CSV
  • New! CSV export for minimum burden distances
  • Improved volume to blast calculation by defining the first borehole to blast
  • Improvement in the plan view (display of inclination, azimuth and lengths; multiple selection of boreholes)
  • Improved report options (adjustable page and font sizes, information of borehole lengths and inclination)
  • Improved error analysis and warnings


BlastMetriX UAV version 3.0.2

The software update includes:

  • Improvement of surface meshing (avoid accidentially formed micro gaps in the surface mesh that have been present under some circumstances)

BlastMetriX UAV version 3.0

Improvements and new features in General, SurfaceTrimmer, and BlastPlanner are equal to BlastMetriX 3D and can be found in the corresponding release notes.

The MultiPhoto component has been extremely improved again. It computes better models with higher accuracy and it is faster than previous versions.

  • Higher quality of 3D models in terms of surface point localization and coverage of data
  • Faster computation
  • Support of standard machines without special graphics hardware; for faster computation still NVidia © graphics cards recommended
  • New matching strategy for “fast” reconstruction leading to denser models at the same computing time
  • “Normal” density matching delivers much more points at the same computation time
  • More information on loaded image data such as camera type or GPS information
  • Automatic support of GPS information if available
  • New live display during coarse model generation; it shows the actually found camera locations in a live 3D view while adding new cameras
  • A custom set of loaded images can be selected/deselected for the reconstruction process
  • Changing the project name also changes the name of the 3D model accordingly
  • Region of interest supports straight lines as well as arbitrary shapes
  • Several new cameras added to camera data base


BlastSiteGenerator 3D
  • The combination of aerial and terrestrial 3D images better detects redundant points


BlastMetriX UAV version 2.1

  • Higher quality of 3D image reconstruction.
  • New! Automatic continuation of reconstruction (dense reconstruction is automatically launched after coarse reconstruction after a user-defined time).
  • New! Three different reconstruction modes (Fast, Normal, High).
  • New! User-defined limit of generated points for the final reconstruction.
  • New! User-defined stereo set-ups can be added to an existing 3D reconstruction.
  • New! 3D model view for a better localization of the reference images.
BoreholeFinder New Software Component!
  • Defines and edits borehole collar positions on reconstructed 3D images; collars can be directly loaded into BlastPlanner.
  • Reference points are saved in the correct subimage and are shown again after loading.
    Note: Reference points from previous versions are no longer imported.
  • BlastMetriX 3D is released with 64-bit applications only.
  • A dongle update is required (for most users) before installing BMX 4.1 in order to apply all new functions to the software.
  • Drastic improvement of 3D mesh generation.
  • Better handling of operations that require administrator privileges (e.g. installation of license or calibration data)
  • Multiple calibration files can be installed and removed at once.
  • New! Multiple connected dongles are supported.
  • New! Option to set the displayed texture resolution for the 3D viewer.
  • New!  Backup/restore functionality for license data.
  • New! ‘Clean up’ button for removing temporary data (only if 3GSM cache directories are found).
  • More feedback during trimming.
  • The description of the Blast Site can be edited directly from the printing/exporting dialog.
  • The set borehole inclination is saved.
  • Even rows in staggered drill patterns (row shift bigger than 0) no longer extend beyond the width of the first row.
  • Azimuth of boreholes is displayed as 0-360° (older versions: -180; +180°).
  • New! Importing borehole rows from “.csv” files allows to add boreholes to the existing drill pattern (previous versions: an existing drill pattern was exclusively replaced).
  • New! Rows can be added to an existing drill pattern.
  • New in BlastMetriX UAV version 4.1: Automatically generated VolumeCalculator Report
  • New in version 4.0.2: User adjustable colour scheme for the visualization of the burden situation on the 3D model
  • New in BMX UAV v4.0: GCP point definition in 3D
