WHATS NEW IN SIROVISION 6? New GUI Design Figure 1: The new Sirovision 6 GUI The MAPPING EXPLORER and ANALYSIS EXPLORER tabbed windows have now been merged in to a single GUI screen.

3 WHATS NEW IN SIROVISION 6? New GUI Design Figure 1: The new Sirovision 6 GUI The MAPPING EXPLORER and ANALYSIS EXPLORER tabbed windows have now been merged in to a single GUI screen. The new EXPLORER window replaces them and displays all mapped objects and analysis sets for the currently displayed 3D image or 3D mosaic. The new TABLE VIEW displays a table of the objects currently selected in the EXPLORER window, e.g. Discontinuities or Survey Lines etc. Selecting any object in any window, e.g. the 3D image, the stereoplot, the table view, etc. will highlight the same objects in all the other windows. This means the user no longer needs to toggle between Image View, Mapping Explorer and Analysis Explorer tabs to view the same highlighted data. Another new feature is if you hover the mouse over a mapped object in the 3D image window, its geotechnical properties are displayed in a floating box so the user no longer has to select a structure to view its geotechnical characteristics. The FIND PLANES tool has been removed due to its questionable results. A new technique called 2D Fusion to automatically map structure is being developed by the CSIRO. Once available, this will be implemented in to Sirovision, possibly in V6.1. Sirovision 6 Release Notes 1

4 The new Explorer Window Figure 2: The new Explorer window The Explorer Window replaces the old MAPPING EXPLORER & ANALYSIS EXPLORER tabs. Toggling a tick box next to an object type will display or not display an object type in the 3D Image View window. By default, when opening a new project, DOMAINS and PORE PRESSURE grids are deselected and so not displayed. New Object Types Domains Geological Domains can be mapped and saved for single 3D images or 3D mosaics and have been added as a new function in the expansion of the SLOPE STABILITY ANALYSIS tool. Select the new MAP GEOLOGICAL DOMAINS icon in the IMAGE VIEW window or from the MAPPING menu. Imported Structures As part of the expansion of the SLOPE STABILITY ANALYSIS tool, Sirovision can now import complex structures as DXF files. Pore Pressure Grids As part of the expansion of the SLOPE STABILITY ANALYSIS tool, Sirovision can now import pore pressure grids as TEXT files. Mineral Classification The new mineral classification tool allows a user to select a sample area Sirovision 6 Release Notes 2

This tool allows you to place the centroid of a plane on a 3D image.

5 and automatically map the same colours throughout the 3D image or 3D mosaic. See Mineral Classification. New Icons Figure 3: New icons in the Image View window ADD USER DEFINED PLANE Figure 4: The new Add User Defined Plane dialog This tool allows you to place the centroid of a plane on a 3D image. You can then manually edit the centroid coordinates and the DIP, DIP DIRECTION & PERSISTENCE of the required plane. This is useful to manually plot a plane for the Pit Wall. Sirovision 6 Release Notes 3

6 MAP A GEOLOGICAL DOMAIN This is a new tool added by the expansion of the Slope Stability Analysis tool. This function allows you map a domain on the 3D surface and enter geotechnical characteristics for that domain such as BLOCK DENSITY, PORE PRESSURE & FACTOR OF SAFETY threshold. See chapter on Significant expansion of the Slope Stability Analysis tool. MINERAL CLASSIFICATION (Colour Classifier) Display mineralogy automatically mapped by color matching. See chapter on Mineral Classification BLOCK VIEW TOGGLE Becomes active when a Kinematic Block Analysis Set has been created. Show Kinematically Free Blocks display only amber (stable with friction) and red (unstable blocks). Show All display red, amber and green (stable without friction) blocks.

7 Performance Improvements Reduction of Image and Spatial Data Resolution and Bit size As the latest digital SLR cameras are commonly at least 16 megapixels and upwards, data storage of photographs and 3D image generation processing speeds are increasing as megapixels and thus file sizes increase. This can mean the 3D image generation processing can be quite slow. Therefore new functionality has been added to allow users to REDUCE IMAGE AND SPATIAL DATA RESOLUTION MINIMISE FILE SIZES The trade-off is that as you decrease resolution, 3D image generation processing speeds will increase, but the integrity and accuracy of the point cloud/wire frame depreciates. This means the accuracy of any structures mapped on that wire frame will also decrease. Generally, for GEOLOGICAL MAPPING, reduced resolution images provide more than adequate accuracy for these purposes. For GEOTECHNICAL MAPPING, it is advised that 100% resolution images are used to obtain the most accurate results possible. The new Spatial and Image Resolution screen A new function has been added to allow users to reduce both the spatial data resolution (wireframe & point cloud) and the image size (textural surface image) resolutions as new photographs are imported. In the NEW PROJECT WIZARD, stereo images are paired together, converted to TIFF and have camera calibration applied as normal. The next screen in the wizard is a new screen called SET IMAGE AND SPATIAL RESOLUTION. Sirovision 6 Release Notes 5

Figure 5: The new Set Image and Spatial Resolution screen This screen has 3 sections: FACE COVERAGE ESTIMATE Figure 6: The Face Coverage Estimate screen This section shows a graph displaying the face

8 Figure 5: The new Set Image and Spatial Resolution screen This screen has 3 sections: FACE COVERAGE ESTIMATE Figure 6: The Face Coverage Estimate screen This section shows a graph displaying the face coverage obtained using the camera and lens used to capture the photographs in the project alongside the Pixel Size on the Face (mm). As you opt to reduce spatial and/or image resolution, changes to the Pixel Size on the Face is updated on the graph to show the changes in accuracy you will obtain at different levels of resolution. Sirovision 6 Release Notes 6

9 IMAGE RESOLUTION Figure 7: The new Image Resolution screen This section allows you to apply three different types of resolution reduction: REDUCE IMAGE SIZE This option reduces the textural image (surface image) by 75%. This value is set at 75% as this maintains accurate scaling without altering the aspect ratio of the image so that structural mapping can still be carried out with reasonable accuracy. REDUCE IMAGE QUALITY TO 8 BITS Bit quality of RAW images captured can be set up on most digital SLRs. If the images have been captured as 12 or 16 bit, the converted TIFFS can be reduced to 8 bit to reduce file size and improve processing speed. The Stereo Camera Mark II captures images by default as 16 bit RAW which are converted to 16 bit TIFFS. SPATIAL POINT DENSITY The number of pixels on your screen to each spatial data point reflects the density of the 3D Point Cloud. The larger the number of pixels between spatial data points, the less dense the point cloud but achievable mapping accuracy is reduced. Sirovision defaults to 3 Pixels per Spatial Data Point. This function allows the user to reduce point cloud density from 3 to 5, 7 or 9 pixels per spatial data point. It also allows the user to INCREASE point density to 1 pixel per spatial data point (should you require absolute maximum accuracy with only a very small increase in file size). Sirovision 6 Release Notes 7

10 ESTIMATES (OF RESULTANT FILE SIZE) Figure 8: The new File Size Estimates screen This section displays the expected file sizes as you reduce or increase image resolution, spatial resolution or alter the bit size of files. This allows users to obtain the optimal trade-off between image and spatial resolution and resultant file size. Sirovision 6 Release Notes 8

Merge multiple 3D mosaics into a single composite image Figure 9: The new Tools drop down menu A new function has been added to the TOOLS menu to allow the user to merge multiple 3D mosaics in to a

This single super-mosaic can be loaded in to Sirovision without the need for all the support files (2D images, task and matching files) used to generate the individual 3D images in Project Explorer.

11 Merge multiple 3D mosaics into a single composite image Figure 9: The new Tools drop down menu A new function has been added to the TOOLS menu to allow the user to merge multiple 3D mosaics in to a single composite image with options to reduce image and spatial resolutions in order to reduce file size and memory requirements. This single super-mosaic can be loaded in to Sirovision without the need for all the support files (2D images, task and matching files) used to generate the individual 3D images in Project Explorer. This function will allow users to analyse much larger scaled images and generate 3D models of whole pits. Figure 10: The new Merge Files screen Any 3D image or 3D mosaic can be selected from any directory and Image Reduction Factors can be applied to each image. An Estimated Output File Size is displayed in MB. If any mapped objects such as structures have already been mapped on a selected 3D image or 3D mosaics to be merged, these objects will be safely merged in to the new composite image. If structural mapping has been Sirovision 6 Release Notes 9

12 completed already, then user can afford to reduce the composite image resolution to reduce file sizes and loading times. SUGGESTED WORKFLOW IS TO MAP STRUCTURE ON INDIVIDUAL MOSAICS FOR MAXIMISED ACCURACY, AND THEN MERGE MULTIPLE MOSAICS WITH REDUCED RESOLUTION TO REDUCE FILE SIZE AND INCREASE LOAD SPEEDS WHILST KEEPING THE ACCURACY OF THE MAPPED STRUCTURAL DATA INTACT. New ability to map planes across 3D mosaics Versions of Sirovision prior to Sirovision 6 did not allow users to map a PLANE across the boundary of an individual 3D image, even if was part of a 3D mosaic. Figure 11: A Plane mapped across 3 individual 3D images comprising a mosaic Sirovision 6 enables planes to be mapped across 3D mosaics as plane data is now more efficiently generated and managed for exportability to other software products including Datamine Studio.

13 Significant expansion of the Slope Stability Analysis tool. Please note, a separate technical manual will be distributed for the new Slope Stability Analysis tool and internal training will be provided to each regional office. Figure 12: A 3D model showing an imported curved structure and automatically detected unstable blocks. Sirovision 6 sees the expansion of the Slope Stability Analysis tool by introducing more sophisticated polyhedral BLOCK analysis in addition to the existing tetrahedral analysis which detects simple WEDGES. The availability of tetrahedral and polyhedral analysis techniques enables users to detect ALL types of unstable blocks in their excavation.

Summary of new functions: Map or import multiple domains and enable input of geotechnical characteristics such as rock density, cohesion and critical friction values for each domain.

Run polyhedral analysis to automatically detect blocks and toppling hazards in addition to tetrahedral wedge analysis. Analyse the interaction of minor and major structures.

14 Summary of new functions: Map or import multiple domains and enable input of geotechnical characteristics such as rock density, cohesion and critical friction values for each domain. Import and display Pore Pressure grids. Import and display non-planar or curved complex structures. Run polyhedral analysis to automatically detect blocks and toppling hazards in addition to tetrahedral wedge analysis. Analyse the interaction of minor and major structures. Run analysis on ALL digitally mapped structures simultaneously, not just two orientation sets at a time. Final analysis considers all of the above to produce a Factor of Safety, physical location, mass and volume and stability classification of all unstable features including wedges, blocks and toppling hazards detected on the rock wall.

Mineral Classification Sirovision 6 adds a new MINERAL CLASSIFICATION function to enable the user to select a sample area of the rock colour they wish to map, e.g. an ore body.

As the Sirovision model is accurately scaled, the software captures coloured bodies surface area data which can be used to estimate ore volume.

15 Mineral Classification Sirovision 6 adds a new MINERAL CLASSIFICATION function to enable the user to select a sample area of the rock colour they wish to map, e.g. an ore body. The software then scans the 3D model or 3D mosaic and automatically maps all occurrences of the colours selected (ore body). As the Sirovision model is accurately scaled, the software captures coloured bodies surface area data which can be used to estimate ore volume. Figure 16: A 3D model showing coal deposits automatically mapped by the Colour Classification Tool. Figure 17: Image Colour Classification output showing surface area data. These Mineral Classification features can be exported via the Export Wizard as a DXF and TEXT file. Sirovision 6 Release Notes 13

16 Dip/Dip Direction Facet Shading New DIP and DIP DIRECTION colour facet 3D view modes have been added. At the bottom of the 3D Image View window there are two new 3D Image View icons. SHOW SHOW DIP Figure 18 : A 3D Dip facet shaded image. Sirovision 6 Release Notes 14

17 TECHNICAL NOTE Operating System Sirovision requires a 64 bit operating system such as Windows 7, 8 or 8.1. Graphics Cards After installation, if the host computer has an NVidia graphics card, the first time the program is opened, the software checks that the CUDA library is at least Version ( ). If it is not, a message displays informing the user to update their graphics driver, so that the latest CUDA library is installed. This is not an error message and does not mean your graphics card is incompatible. Sirovision 6 Release Notes 15
