Laser Scanning Technologies: Which Should You Choose?
A wide variety of hardware has emerged in the 3D measurement and documentation sector in recent years. As project owners and engineers, we frequently ask, "Which device should I use?" Fundamentally, we can divide the technologies into two categories: Terrestrial Laser Scanning (TLS) and Mobile Mapping (SLAM).
1. Terrestrial Laser Scanning (TLS)
Devices that are mounted on a tripod and perform 360-degree scanning while stationary (e.g., Leica RTC360, Faro Focus).
2. Mobile Mapping (SLAM-Based)
Handheld or backpack-mounted devices that scan while walking (e.g., Leica BLK2GO, NavVis VLX). They use the SLAM (Simultaneous Localization and Mapping) algorithm.
Comparison Table
| Feature | Terrestrial Scanner (TLS) | Mobile Scanner (SLAM) |
|---|---|---|
| Accuracy | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ |
| Speed (Field) | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Image Quality | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ |
| Cost | High | Low (Per unit m²) |
Eos Proje Approach: Hybrid Solution
We don't rely on a single technology. We generally use the Hybrid Method in our projects:
This way, we maintain the millimetric accuracy of Terrestrial scanning while benefiting from the speed advantage of Mobile scanning to optimize costs.
