2 The debate: Point Clouds vs. Imagery Both are useful pick the right tool for the job (or both)

3 The debate: Point Clouds vs. Imagery Both are useful pick the right tool for the job (or both)

4 Perception and Interpretation Computers understand: Digital information Patterns Pixels and points Information contained in databases Logic Algorithms Active measurements (i.e. laser) Point clouds are thus useful for automation, change detection, documentation and high accuracy processes Point Clouds! Humans understand: Object based visual interpretation (some advanced software can do this too) Analog world 3D perception via passive or photogrammetric processes (two eyes) Decision making based on what we see: what the eye sees the mind, in general, believes Humans can interpret and act more rapidly with imagery based information as it mirrors their real world experience Images!

5 Case Study 1 South Africa (Transnet)

6 Introduction Optron South Africa, Trimble dealer for more than 25yrs Full Geospatial Solution Provider Resolve Solution Provider (elogics) Resolve is a venture that merges a group of 3 companies. The separate entities operated successfully over more than a decade, with key synergies now being embraced to offer our clients holistic, end-to-end solutions. Focus on innovation finding ways to optimise, align and integrate the strategic and operational value drivers in business [process, technology, assets, people].

7 Opportunity Transnet Freight Rail (South Africa) -bid specification for Rail Asset Data capture to update current database Project coverage, 15,000km of rail and 10,000km of Road (adjacent to the railway) across South Africa Mobile system used for project was Trimble MX2 with Trident Office Software

8 Bid Requirement Track and Road centreline 360 Imaging of environment Video record of entire track route 3D Laser data Rail Asset Feature extraction Update database of current Assets Rail / Road centre line Use GPS trajectory Proof of Concept Prior to Award of Tender Difficult to meet with most mobile mapping systems

9 Trimble MX2 The Trimble MX2 is a versatile mobile mapping system that includes: GNSS/Inertial Positioning System Rotating Lasers (Lidar) 360 Camera Designed for use on any vehicle Designed for easy installation Simple to use Delivered with an established mobile mapping workflow (Trimble Trident software) Low power requirements for mobile deployment Low maintenance minimal moving parts Achieve balance between cost and performance

10 Proof of Concept (POC) Route 60km from Brits to Mamelodi Vehicle - Rail Car Mount system onto the vehicle Data Capture Post Processing Data / Deliverables

11 Trimble MX2 POC - Route Versatile Install on a wide range of vehicles No complex computer racks operates from a laptop Operate with laser only or add 360 camera (optional) RTK or post process positions for vehicle trajectory Simple Easy to install Laptop only Few cables Simple design with few moving parts Rugged IP65 Designed for on or off road use Single axis laser rotation

17 Case Study 2 Western Australia (Land Surveys)

18 Trimble MX2 Rail Asset Survey Project Overview Pilbara region in the north of Western Australia 350km of new privately owned rail Purpose Rail track assets Signalling and communications System assets

19 Trimble MX2 Rail Asset Survey - MX2 with LadyBug 3 camera mounted on hi-rail 4WD vehicle - Single pass runs - Trident Capture Run lengths 10-15km - Capture Speed 35 km/h - 60 km captured per day (2 static base setups) - RTK GNSS survey conducted prior to Mobile acquisition for use as Validation and Vertical Registration targets

20 Trimble MX2 Rail Asset Survey - Adjusted trajectory created in POSPacMMS - Trident Imaging Hub utilised for: - QA/QC of point cloud against RTK GNSS validation survey and adjoining point clouds - Point Cloud/Run processing - Registration of point clouds in Z - Feature extraction from a combination of imagery and point cloud - Third Party software used for Rail Alignment Extraction
