Kevin Perkins Applanix Corp. NATIONAL SURVEYING, MAPPING & GEOSPATIAL CONFERENCE - MARCH 13-17, 2017 Trimble Indoor Mobile Mapping Solution
Why Indoor Mapping? The need: As-built maps/models of indoor spaces, buildings, tunnels, plant sites etc. Any non GNSS locations.
Why Indoor Mapping? The challenge: Traditional static surveys and scans are costly, time consuming and disruptive. Data acquisition, processing, modeling and deliverables need to be timely, efficient and productive.
Why Indoor Mapping? The solution: Various indoor mobile mapping solutions acquire Lidar point cloud and photo imagery to various degrees of accuracy, precision and efficiency. Mobile Indoor mapping solutions selected depend on the required deliverables: mapping accuracy of assets, size and complexity of space to be mapped, physical constraints of space to be mapped (people, functionality of building etc.)
The Solution Trimble Indoor Mobile Mapping Solution
What is TIMMS? Trimble Indoor Mobile Mapping Solution An optimal combination of technologies (lidar scanner, spherical imagery camera, inertial measuring unit - IMU, POS Computing System PCS, ergonomic platform) for capturing spatial data of indoor and GNSS-denied spaces and creating 3D, georeferenced models.
TIMMS Components: Four core elements: 360 degree spherical camera Lidar engineered to work indoors in mobile mode Computers and electronics for completing data acquisition Applanix advanced positioning system (PosLV)
Key features of TIMMS: No need for GNSS Little or no Lidar shadowing Extended range of operations Self-contained Simple workflow Trimble Connect allows users to access data anywhere, using a standard web browser
Key benefits of TIMMS: TIMMS is a highly efficient and easy-to-use solution for collecting, accessing, displaying and analyzing 360 degree spherical imagery and Lidar data of indoor spaces. High accuracy Relative accuracy of 2 cm Low cost per sq. ft. High productivity > 225,000 sq. ft. /day, 45 rooms/day 2D data next-day delivery 3D data Fully customizable
TIMMS Applications Building Security Situational Awareness Emergency Response - Evacuation Asset Management Physical assets, space assets Renovations Building Information Modeling New construction as-built Tunnels Space Optimization building move-in/out Possible to collect outdoor data All interior spaces
TIMMS Market Segments Public Security & Safety Government buildings Airports, subway, train stations, transportation facilities Public venues (stadiums, auditoriums, theatres, historical venues) BIM, MEP & Engineering Plants, refineries, warehouses, retail Commercial (Property Management & Development Companies) High rise office, residential, government Tunnels Highway, sewer, mines Covered Pedestrian concourses (above and below ground) with platforms, corridors, stair locations and ramps
Key deliverables of TIMMS: 3D Lidar point clouds that are dimensionally accurate in real-world coordinates 3D geo-referenced spherical camera data sets for the entire captured area A set of in-building floor maps of the captured areas Easy, intuitive maps for individual buildings and building spaces Fly thru Viewer (TIMMS Site Viewer, Orbit etc.)
TIMMS Process Overview
TIMMS Workflow Indoor modelling is done in 3 easy steps: Step 1: Collect Lidar data by walking the TIMMS cart through physical spaces Step 2: Process the data using Applanix POSPac MMS software Step 3: Create accurate models of space using building design software such as EdgeWise, Autodesk Revit, SketchUp etc.
TIMMS Workflow: Step 1 Collect
TIMMS Workflow: Step 2 Process Geo-reference the data using Applanix POSPac MMS software
TIMMS Workflow: Step 3 Model Create and refine accurate models of space
TIMMS Visualization & Modeling Visualization of.las files (Trimble RealWorks Viewer, Quick Terrain Reader etc.) Modelling with software packages 2D and 3D CAD models 3D point clouds TIMMS Site Viewer on TCC (Trimble Connected Community) viewing interface incorporating spherical imagery and 3D model
SketchUp Extension
TIMMS Sample Data 4 Level office building 11,350 square meters Acquired with TIMMS in 3.5 hrs. Point cloud available next day
Case Study - LAX International Airport THE NEED Scan and geo-reference over 1.8 million sq. ft. of airport terminal space Produce accurate as-built models for GIS Document all assets: chairs, booths, ticketing stands, computers SPECIAL CHALLENGES Airport must remain open scan while occupied Must be done quickly and accurately Minimal impact on airport operations SOLUTION TIMMS indoor mobile mapping system from Applanix Applanix scanning and data development personnel/services
LAX International Airport RESULTS Scanned 1.8 million sq. ft. in under 30 hours, reduced from 21 days using traditional tripod based Lidar method No airport closures Produced full, complete, accurate as-builts Minimal impact to airport operations Using the Applanix TIMMS platform for data collection enabled us to scan over 1.8 million sq. ft. in under 30 hours. This process would have taken in excess of 3 weeks using the traditional tripod based interior scanning methods. We really enjoyed working with the Applanix team and look forward to future projects. Ed Maghboul, President, x-spatial
Case Study: Pictometry/Northern Alberta THE NEED Pictometry is merging indoor georeferenced data with its library of geo referenced aerial imagery 91 building interiors (millions of square feet!) for the Regional Municipality of Wood Buffalo must be mapped Must be fast SPECIAL CHALLENGES Many different buildings of all sizes, shapes, and functions including water treatment facilities Many buildings without elevators meaning staircases to be managed Using the old way manually tying images together this project could not have been completed. It simply would have taken too long. We needed a new way. Scott Sherwood, VP Pictometry Need it done quickly and cost effectively Harsh environmental and weather conditions SOLUTION TIMMS indoor mobile mapping system from Applanix Applanix scanning and data development personnel/services
Case Study: Pictometry/Northern Alberta RESULTS Produced highly accurate digital 3D blueprints of 91 different government buildings Models built using SketchUp 3D modelling software Worldwide access for customer on Trimble Connected Community (TCC) Final models uploaded to the Pictometry Critical360 web platform The TIMMS cart performed as we hoped. We captured over 90 buildings quickly and accurately. The Applanix team was very knowledgeable in the data capture techniques and trained our staff so that we were able to complete the last several buildings of the project ourselves.
