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. Needless to say the P40 performed tremendously and got a great scan in only 1hour 30mins with 4 setups on the highest resolution.
After doing this demo other customers who owned C10 & P20 ScanStations 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 MS50 customers.
The scan time for the C10 was 4 hours 30 mins 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.
The MS50 Robotic Total Station/Scanner was also used to demonstrate another scanning solution. The scan time for the MS50 was 2 hours 20 mins 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.
Here are YouTube videos showing the flythroughs of the different point clouds generated by the ScanStations and MultiStation.
One aspect of the Leica P40 ScanStation to consider is that it has the "Range Mode" which 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 P40 was capable of acquiring a glass/steel high rise at over 897 feet away.
This is just a brief run through of this one demonstration. If you would like more information or would like a demonstration customized to your needs please contact me.
The Leica ScanStation P20, C10 and MS50 used in the demonstration are currently available for sale at 20-30% off. Let me know if you are interested.
