Join Irene Radcliffe for an in-depth discussion in this video Scan navigation overview, part of Learning FARO PointSense Plant.
- [Instructor] Now we're with chapter six, we're going to take a look at scan navigation. When you look at your scans using recap or VirtuSurv you can see a clear plainer image of the scans using the mirror balls and the 3D view feature. When working in autocap, we can also view the data using this method. We can use the scan navigation tools in order to filter the points and see only the data captured by each individual scanner. Let's take a look at scan navigation and learn how to use it as we model. So we are going to navigate to our exercise files to desktop.
Exercise files and chapter oh six oh one. So, let's take a look at our scan navigation panel. So, it comes in our point sense plant tab, and this is the panel we're going to be working with right here. The first thing we're going to do is we're going to create the scan labels using the tool on the top right hand side of this panel, create scan labels. Now we're going to use recap. Recap is the best option to use because, that's going to duplicate the exact same scan positions that we used inside our recap file, so, I'm going to choose that, and you'll see that it creates these little orange spheres inside our point cloud model, and if I turn on our transparency here, you'll see that their numbered or their named exactly the same way inside recap and inside VirtuSurv.
So, if we want to actually jump into the scan locations once we've created our scan labels, we can come up here and turn our scan navigation on. So, I'm just going to come in and double click the scan label. Now you'll see here, because we've got selection cycling turned on autocap's not sure if it wants to actually pick the scan label or the point cloud, because the points are over lapping and they sit on top of each other. So, if you have your selection cycling turned on, you can then go back and say: "Yeah, we want to take the cubic scan label and that's going to jump you into the scan navigation position.
Turn transparency off, and then being able to use my middle mouse button to hold down and pan, I can look around and see exactly what that scanner saw when it was in that position. Now I can look all the way up, and around in the full 360 view here. And again, it's hard to imagine, but this is actually points inside autocap. This is a great way to model, because if we zoom in on this and you see behind that, we don't have any additional points, we just have gray space you can see behind the points.
So, when we work with a 3D view and we pick a point we're not really sure if we're picking the point on the item we're modeling, or the point behind it. This filters put those points. We're only actually picking the points on each object that we see. Once we're in a scan position, we can just double click into the next scan and we can navigate and move through this way too. That takes me into that scan position, and again, I can go out even further. Just click the next one and see what that scanner saw, click the next one and you get how that works.
So, that's how we work with our scan navigation. If we go back to our 3D view, if we want to go back, we just come back up to this area here, we turn our scan navigation off, which jumps us back into the 3D mode again, and if we want to continue modeling this way, but we don't want to see these scan labels. They can get in the way or block the view of something, we can come up back to our scan navigation panel, and choose the button here and we can hide those scan labels, and then their gone.
We can bring them back at anytime just by show them again. I'm just going to hide these and now you can see the value of having filtered point clouds and available inside autocap. It makes it much easier to see what we're working on and much easier to visualize and easier to pick points, because we're not worried about what sits behind, we're only viewing the filtered points that we're taking from our particular scan location.
