Reality Capture: From Point Cloud To Design To Visualisation by Shuaib Yunos, Baker Baynes
Perspective: Design & Construction Designers are conceiving buildings differently. Building owners expect a lot more from designers and contractors. The physical building can now be deeply interconnected by digital systems. Larger & More Complex Projects Interconnected Lifecycle Stakeholder Understanding Resiliency
Challenges Faced: Design & Construction 2D As-Built Reality Data 3D / BIM Design errors caused from inaccurate existing conditions Implementing 3D/BIM for renovation projects Monitoring build progress against design intent
Required Deliverables Upgrade of existing infrastructure Provision of new infrastructure Catalyse production & proficiency Time-efficient workflows Economical & viable processes Crucial infrastructure and processes need to be prioritised and streamlined in a sequential, effective manner such as the development of roads for access, structures for shelter and services, planning for future growth, geotechnical data modelling, geospatial elements, etc.
Solution: Adoption of technologies Tasks need to be accomplished in a workflow that integrates practicality, efficiency and technology to achieve the desired objective in the most optimised, economical and time efficient manner. Therefore, innovation and technology need to be fused to achieve the desired outcome in the most practical, optimal and efficient ways possible
Technology focus: Autodesk ReCap What is ReCap? Autodesk ReCap (ReCap derived from Reality Capture), is the first industry solution to bring together both laser scanning and photogrammetry into one streamlined process.
Technology focus: Autodesk Recap What is ReCap? Recap allows designers, engineers, and builders to integrate reality capture data into their design and building process. Utilizing laser scans or photographs, ReCap catalyses designs by transforming the real world into as-built 3D data
Advantages of ReCap Reduces Revisions from design errors that occur when using inaccurate existing condition information. By designing from real world conditions, architects and engineers can avoid clashes or issues that might arise during construction. Speeds the design process by bringing a 3D representation of current site conditions into design tools. This is especially important for those just getting started in BIM and moving from a 2D to 3D workflow. Starting a design within an 3D context provided by ReCap, this drastically reduces the barrier to adopting BIM.
Advantages of ReCap Save time and reduce overheads by capturing the site in one visit in an efficient and automated process. This replaces the tedious process of manually documenting the site using basic measuring devices (tape measure / distance meter) and eliminates the need to return to the site multiple times to validate accuracy. Easy to get started regardless of previous experience with reality capture data or scanning. ReCap Pro has one click tools that automatically register / stitch and clean-up data, preparing it for use in Autodesk design tools.
1. Capture How It Works Take photographs or laser scans of a landscape or building 2. Compute Convert photographs and laser scans into 3D reality data Measure, annotate and collaborate on data 3. Create Import point clouds into Autodesk portfolio products Create reports, drawings, designs and models Share project s progress through VR
ReCap Workflow Upload photos & GPS coordinates Create point cloud on ReCap 360 web Export point cloud Revit FY14 Upload scans Combine laser scan data & photo data Export point clouds
