Hi,
first of all, are your laser scans in local system, which is reduced coordinate of OSGB system? If so, you can set output system to OSGB and then during export use transformation settings to “get back” the original coordinates (unfortunately this is not tested).
Or you can use the geoinformation from drone images to get that geo info. But for that you will need to reprocess your project.
Hello everyone, since I have not been able to generate a new query. I’m asking if it’s possible that you can help me.
I’m trying to create a point cloud of a rock face, but I need to georeference the model with respect to north.
The model generates it completely, but it does not position me with respect to the north. How can I enter georeferencing from control points knowing the course and direction, without coordinates? it’s possible?
Hi @Jignaciobg
This should be possible if you know where the north is.
RealityCapture uses the axes as X is pointing to the east and Y to the north. So using some coordinates around your model (as [1,0] for the point on the east side of your model, [0,1] for the point on the north side of your model and [-1,0] for the point on the west side of your model) should orient your model properly to the north. You can also use the proper values to get your model scaled.
Groan…this is the merger of an image component and the laser scans as before. A tennis ball!
Its 2:00 am again, why is this so difficult? I use my Autocad analogy again, two drawings in the same coordinates, boom, together as one. This is why we use coordinates.
Here’s a thought. In the laser scan scene, we import the ground control targets and scanner targets to verify the position. I don’t need to pick targets in the scans again. Lock the targets into the component. Open the image component with the very same targets, import the scan component. “merge by targets” first before you do your thing. Now that is just maths.
Another attempt
This is the end result of the alignemnt.
