Hello,
Does anyone have a workflow recommendation for combining photographs with point cloud data? I'm trying to make a reconstruction of a room using photos to capture the details and the point cloud will help with the plain white walls. I am using a basic DSLR camera and a FARO Focus scanner. Does everything need to be geo-referenced for me to be able to combine the data? If so, is there a link where I can learn how to do that? Right now, after I do the aerotriangulation on the photos and then import the scans as .e57 files, the program no longer gives me the option to create a reconstruction or to run another aerotriangulation using the scans as a reference.
Also point cloud shouldn't be much larger area than covered by photos otherwise it also can fail as lot of points are considered too far from photo tie sparse point cloud.
The point cloud and the photos both need to be in the same coordinate system and be 'within a couple of meters of each other'. Then the program can snap them together.. You would have to have located targets that get scanned as well as photographed. The scans need to be georeferenced in your scan registration software. The photos get survey control put on in ContextCapture.
Once I start with the .e57, the option to attach images is removed. There also does not seem to be an option to similar points between the scan and images.
Start with the .e57 and use that as your geometry. Then attach your images to it using key points that you can define both within the scan and images.
I have exactly the same problem; I have DSLR photos of buildings which gives the bulk of the model quite well, but where there are large plane surfaces, with no surface detail, photogrammetry does not work. It also cannot cope with narrow complex areas where I cannot get far enough away to capture detail with a camera. I have laser scans covering both types of areas but CC does not appear to have any mechanism for including the position data from within the laser scans within the AT. It is impossible for me to get the location of the laser scanner other than via a link through the AT.
This inability of CC to be able to incorporate e57 files at the AT stage is a big disadvantage.
