Texas Leica Geosystems representative showcases Leica ScanStation, MultiStation

G4 Spatial Technologies recently conducted a comparison of the Leica ScanStation P40, Leica ScanStation C10 and the Leica Nova MS50 MultiStation.Below are the results Joel Schwirtlich, G4 Spatial Technology HDS Technical Sales and Support specialist, compiled.

This comparison began with a P40 Demo for a graphics design group. The customer wanted to see how the Leica P40 ScanStation would do with St Mary’s Cathedral in Austin, Texas, USA.

Leica ScanStation P40

One aspect of the Leica P40 ScanStation to consider is that it has the “Range Mode” that gives you a range of 270m at 500,000 points per second. Below is a snapshot from the point cloud it generated from an adjacent intersection.


We did this demonstration for a customer to show the range and quality of the return. The Leica P40 was capable of acquiring a glass/steel high rise at more than 897 feet away.
Needless to say, the Leica P40 performed tremendously and got a great scan in only 1 hour 30mins with 4 setups on the highest resolution.
After doing this demo, other customers who owned Leica ScanStations C10 and P20 inquired how theirs compared. So, I went back to the Cathedral and replicated the same demo for a simple comparison. I also added the MultiStation to the mix for some of our Leica MS50 customers.

Leica ScanStation C10

The basic outline of the demo was getting the highest quality scans in only 4 setups. With the P40 and P20, this was easily accomplished with the ability to scan at 1 million points per second (“Speed Mode” 120m range). The C10 scans at 50,000 points per second, so to accomplish a similar resolution (High Resolution .05ftx.05ft), it took longer but the quality was still very good (acquired points out to 300m). The scan time for the Leica P20 and  P40 was 1 hour 30 minutess this included a full dome scan at .23in@30ft, then a window/detail scan of the church only at .03in@30ft and HDR imaging at each of the 4 setups.
The scan time for the Leica C10 was 4 hours 30 minutes. This included a full dome scan at .1ftx.1ft, then a window/detail scan of the church at .05ftx.05ft and imaging at each of the 4 setups.

Leica Nova MS50 MultiStation

The Leica Nova MS50 MultiStation, which is a robotic total station plus scanner, was also used to demonstrate another scanning solution. The scan time for the Leica MS50 was 2 hours 20 minutes. This included a window scan of just the Cathedral with setting the resolution at .08ftx08ft at a mid distance (ranging from 65-185ft) and panoramic imaging at each of the 4 setups.

Here is a snapshot of the results.
