Maptek bring augmented reality to mining industry

Latest PerfectDig software provides detailed 3D visual and spatial analysis information

MAPTEK have launched PerfectDig which brings together 3D modelling, laser scanning and handheld communication devices, allowing operations to effectively monitor excavation progress by comparing actual surfaces against designs.

PerfectDig automatically combines mine plans and design information from Maptek Vulcan with laser scans of working areas. Detailed 3D visual and spatial analysis information is then provided in near real-time, directly to production managers and mine crews. This streamlines communication between surveyors, mining engineers, supervisors and equipment operators.

Furthermore, pit or shift supervisors can access PerfectDig via their smartphone, tablet or laptop, creating a real-time decision support and quality control system for mining. Importantly, adjustments can be made before problems arise to ensure efficient overburden removal and maximum mineral recovery.

While Maptek’s I-Site laser scanner captures surfaces during mining operations, PerfectDig automatically determines the location and registers the scanned data against the mine survey grid. This data is geospatially accurate and up to date.

The user can access PerfectDig on a tablet and compare scanned surfaces against the design imported from Vulcan. Different layers can be selected for display so the user can instantly view detailed sections, photos, volumes and other data. Based on specified tolerances, the degree of conformance to plan can be assessed, the excavation can be adjusted and the design updated.

Overlays showing the conformance to plan parameters are then made available via a secure online server to other employees (eg production operators, pit designers, managers etc). In less than 10 minutes the visually rich spatial feedback is conveyed to mine production.

There are immediate safety benefits with PerfectDig. First, there is a reduced need to access working areas by foot for survey and setting out of planned works. Secondly, the high level of detail and measurement accuracy will help ensure wall design batter angles are met and any non conformities are managed during construction – reducing the risk of problems later.
