 Camera GPS Coordinates: shows a preview of the GPS coordinates via OpenStreetMap  Enable/Disable confidence: allows to see/hide information about the dense point cloud confidence  Optimize camera parameters: this tools allows to run a further bundle adjustment, in order to improve the accuracy of the Structure from Motion algorithm. It's advised to run this tool before running the Multi View Stereo phase (dense point cloud extraction). Tip: a typical case in which the bundle adjustment step is required is when the first camera orientation step has completed with a mean reprojection error value above 1: after placing at least three control points from the images it is possible to run the "optimize camera parameters" step, giving much more weight to the defined constraints. Tools - Point Cloud Filters From this menu it's possible to applied the selected mesh filter to a dense point cloud in the workspace. Decimation: select the desired point cloud with the dropdown menu and the number of desired points. The point cloud will be regenerated decimating the point count to the maximum specified value. Densification: select the desired point cloud with the dropdown menu and the number of desired points. The point cloud will be regenerated densifying the point count to the maximum specified value. Only structured point clouds can be densified. Project on regular grid: with this filter it's possible to use a regular grid as a projection for the dense point cloud, so that points are at a regular distance. You may define the grid spacing as well as the grid research value for the grid generation. This tool is
