Advantages of Handheld Lidar Scanning


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 handeld laser scanning, see how it compares to tripod-based systems, and address a few misconceptions out there.

Advantages of Handheld Lidar Scanning

Paracosm PX-80 iHandheld Lidar Scanner 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.

Lidar Scanning Speed cs 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.

PX-80 Handheld Lidar Scanner is Harmless to the Eyes

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 not and Issue
Scan indoors, outdoors, or in low light conditions. PX-80 can scan a variety of sites in nearly any lighting.

Retrace Your Lidar Mapping Project
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.
