The Benefits of Mobile LiDAR Scanning

Posted by Julie Matheney on 2/5/19 1:23 PM

Whether you’re a laser scanning master or new to the game, now is a great time to adopt a mobile 3D scanning solution. Let’s get down to business and discuss the benefits that can be reaped from the PX-80, see how it compares to tripod-based systems, and address a few misconceptions out there.

PX-80 is ~15X faster than tripod-based systems.
In a 3rd party evaluation conducted by the Center for Advanced Construction Information Modeling at the University of Florida, the same 8,000 square foot site was scanned 6X with both a Faro Focus and the PX-80. The total scanning time of the PX-80 proved 9X faster than the Faro Focus and the overall workflow and post-processing time, including registration, was about 16X faster.

Speed vs Accuracy?
It’s no secret that we think accuracy is overrated. The laser scanning industry has done a great job making a big fuss about accuracy, however, millimeter accuracy isn’t always needed and for many projects it’s overkill.

In using a mobile scanner, there’s a trade off: you increase speed and decrease accuracy. It’s simple. You can spend a bunch of time setting up a tripod scanner, getting it positioned just right, and take a super accurate scan -- but with a fixed line of sight, it might take you a while depending on the size and complexity of your project.

A mobile system is more plug and play. You turn it on, walk through your site, and that’s it. You can cover a lot of ground in a short amount of time. Right now, our relative accuracy comes in around 2-3 cm, which for many, is more than good enough.

Freedom from the tripod.
Capture projects in minutes instead of hours and skip the setup and constant repositioning of bulky tripods. Without the cumbersome setup, you’re free to scan as much as you want, as often as you'd like.

Keep your crew safe and stop hiding from lasers.
The LiDAR sensor in PX-80 is the VLP-16 Puck by Velodyne. It’s a Class 1 Laser, which means that it is harmless to the eyes, similar to the laser found in CD-ROM players in terms of safety.

Lighting is never really an issue. 
Scan indoors, outdoors, or in low light conditions. PX-80 can scan a variety of sites in nearly any lighting.

RETRACE your steps. Literally.
PX-80’s companion software, RETRACE, allows you to go back in time and retrace your steps from anywhere in the world, in a Google "street-view" style. This is great for remote teams or simply improving your documentation. If you like to take PX-80 for a spin, request an on-site demo today!
