PointCloudGenerator: Post-filtering and grouping

“

- [Instructor] We're back to the 2D view to show you the post filtering and grouping features in the PointCloudGenerator node. I'm going to analyze the sequence one more time so that we get the default keyframes. Then, we're going to track all the points and get a brand new PointCloud. Done and click Track Points, one to 100, Go, PointClouds as wireframe. Post filtering is the process of removing rejected points. Now, you get to set the rules of rejection right here. First of all, the angle threshold. This rejects points of less than the angular parallax set in this filed. If I raise this up, it'll reject points that are larger and larger angle. So far, everything I have has greater than 10.8 degrees of parallax, so it's a keeper. But if I go up high enough, ah, there's my red, so it has marked the reject points in red, and this means those points have an angle threshold that are greater than 14.6 degrees. The next filtering parameter is the density threshold. This is actually a…
