Many reality capture pros now use hybrid reality capture workflows with mobile mapping devices, terrestrial laser scanners or drones, combining the strengths of each.
From a NavVis blog post by Sean Higgins.
You’ve heard the debate. Are mobile mapping devices better than terrestrial laser scanners? Are terrestrial laser scanners better than drone photogrammetry? Is 360° photography secretly better than all of the above? Which 3D capture tool is the best?
These questions may seem complex, but the answer is simple. According to Mark Hanna, president and founder of PrecisionPoint, the “best” capture tool is often more than one capture tool.
Hanna is among a growing number of leading professionals that now use hybrid workflows. They bring TLS, mobile scanners, and/or drones into the field, and then use each one for the job it does best. Then, with judicious use of survey control, they combine these data sets into a single point cloud for their customers.
The benefits are huge. This hybrid approach offers greater flexibility. It helps technicians adapt to the real-world challenges of any site. And, it enables providers to better serve their customers.
To illustrate just how powerful hybrid workflows can be, we’ll show you how some leading providers are combining capture tools to handle their toughest projects.
SurvTech Solutions: Mobile & TLS
American service providers SurvTech Solutions have started combining mobile scanning and TLS for large captures. Recently, the company wrote about documenting the historic Perfecto Garcia Brothers Cigar Factory, a historic building that sprawls over 44,000 sq ft of Tampa, Florida.
To capture the interior, SurvTech Solutions used a NavVis M6 mobile mapping system, which enabled them to work up to 10 times faster by moving at a walking speed.
To capture the façade, the team used a terrestrial scanner. This TLS offered the range to complete the documentation with a minimal number of set ups.
SurvTech Solutions say this hybrid workflow helped them offer their customer faster turnaround and lower project costs, all without sacrificing on quality. They also plan to recreate this workflow for a variety of projects going forward.
“The use of both pieces of equipment combined,” the company writes, “yields highly accurate and precise measurements in all situations and environments.”
