Correspondence view quality control

- [Instructor] In this video I'll demonstrate … how to quality control your 3D Laser Scan registration … using the correspondence view. … With this technique you'll be able … to quickly identify errors and resolve them … with a methodical registration workflow … that will greatly increase your chances … for registration success. … What I have here is the Beaverton Round dataset. … And what I'm going to just show you in a very simple way … is how this color can help you identify error. … And in this dataset right now … we have about six scans, right? … So I've registered those using … just top down and cloud to cloud, one iteration each, … or in other words I ran that preprocessing one time. … There was actually 300 iterations in that. … But we're going to look at this data … and just see how it's lining up together. … This is actually better than grayscale … to see the data alignment. … So if I just kind of zoom in here, … and I want to look at different colors … to see how all those colors are matching up. …
