ShapeMetriX3D is an innovative system to acquire surfaces with three-dimensional images.
For data acquisition a standard digital camera is used which is calibrated by software from 3GSM. With it the area of
interest is (freely) captured from two angles.

Figure 1: ShapeMetriX3D principle: a 3D image is computed from digital photos; it conserves the visual and
geometric situation.

From the photos a 3D image is computed using award-winning software from which measurements are taken.

​Features:
Reproducible acquisition of rock mass conditions
No more access problems and no pressure of time for the assesment
Measurement of position, distances, areas
Sectional views (cross sections), profiles
Measurement of spatial orientations (dip angle & dip direction)
Geological/geotechnical assessments
Discontinuity spacing
Hemispherical plots
Discontinuity set clustering
Statistics on spatial distribution of orientation measurements.
Scanline
Discontinuity modelling
Data export (CSV, DXF, OBJ)

​Examples

well as identified joints sets in a hemispherical plot.

BlastMetriX3D is an innovative system for bench face surveying and planning of blast layouts based on
three-dimensional images. After setting up field markers at least two photos are taken using a pre-calibrated digital
SLR camera. From the photos a three-dimensional image of the bench face is generated by purpose built software.
The result is a metric 3D image representing a dense three-dimensional survey of the rock surface.
Using another software component the geometry of the blast is planned, optimized, and plan views for drilling and
documentation purposes are generated.

Figure 1 : The BlastMetriX3D principle: from freehand taken pictures (1) a 3D image (2) of the bench face is
computed. The 3D image includes geometry and geology of the bench face and thus allows for an optimal planning
of the blast site by visualising the true burden over the entire area (3), as well as profiles and plan views (4).

​Features:
increases working safety (contact-free measurements).
allows for an optimised loading and subsequently for better blasts.
reduces production costs (independent reports exist).
provides reproducible documentation (conservation of evidence) at a degree of quality superior to measurement
  techniques without imagery.
allows to incorporate geological assessments during blast planning.
provides essential support in fly-rock prevention and vibration reduction.
is efficiently applied on site and quickly learned due to its ease of use.

​Examples

​Step 1  3D image generation​

Figure 2: 3D image of a bench face together with planned boreholes and visualised profiles. In addition to the
geometric blast planning, the quality of the rock surface becomes assessable. From the 3D image weak zones or
more fractured zones are rated in a straightforward manner.

​Step 2  Planning the blast​

Figure 3: Colour-coded visualisation of burden over the entire bench face (categories configurable) highlights light
burden areas (red zones)

Figure 4: Drill pattern with minimum burden diagram of selected borehole as well as geometric parameters such as
length of borehole, inclination, location of collars etc. Each hole is individually adaptable; profiles, minimum burden
diagrams, and colour-coded burden over the entire area serve as data basis.

Complex geometries

Large blast sites (latitude several hundred metres) or corners are acquired by merging several images.

Figure 5: When capturing a corner several imaging locations are required. The software merges them without using
any special markers

Figure 6: 3D image of corner with colour-coded burden over the entire area. In this case the importance of a true
360°search for the minimum burden becomes particularly evident as otherwise light burden zones around the
corner would be missed.
