In the past, the best way to generate floor plans involved taking to the field with handheld distometers (or even cruder devices like tape measures), gathering measurements, and then recording a final deliverable manually. Though this process is effective for smaller facilities, it doesn’t scale to enable efficient, accurate capture of larger facilities.
The rise of reality capture promised to solve that problem. The idea is simple: Use a laser scanner to capture the facility in 3D, bring that data into modeling software, and generate a floor plan for any asset.
In reality, 3D scan-to-plan technologies have proven to be far more complex and expensive to implement. Here’s what’s wrong with these workflows—and a look at the ways that new technologies can address these pain points to exploit the full potential of the scan-to-plan workflow.
Complex Modeling Process
Manual modeling is slow and complicated, and requires significant amounts of office hours to achieve a final deliverable—meaning there is a high chance of human error.
Most companies already work in a wide variety of tools, and are put off by the cost and effort of learning another new software for a single application.
Working with a third-party modeling firm exceeds the budgets of many projects.
Mobile Scanning and Automatic Modeling
Efficient Capture of Large Facilities
A mobile scanner captures field conditions as you walk, which means better coverage and less time in the field.
Simple Data Processing
Some mobile scanners offer highly automated registration workflows that any AEC professional can perform. The Heron, for instance, uses a simple three-step process.
Smart floor plan software automatically finds and models most walls and levels in your as-built 3D data from terrestrial or mobile scanners. This means a minimum of manual steps and no need to learn new software.
High Global Accuracy
Mobile scanners can introduce errors over time that cause your final data to “drift” and reduce global accuracy. Some mobile 3D scanners, like the Heron, will offer options for using survey points or previous 3D captures as control, and use this information to offer reliable accuracy.
This workflow empowers users to generate comprehensive floor plans for extremely large facilities, without sacrificing on the accuracy of the final deliverable.
