Rasterization of the RGB data in Hi-resolution

Post by JManning »

I'm aware that CC does a lot of complicated stuff with scalar fields and rasterization, etc.
What I want to do is fairly simple but I can not find and references to it on these forums.

Pretty simple, I have a series of scans done on a parking lot and two streets around it. I have merged all the scans into one layer, trimmed the points I don't want, and I am left with the cloud in the attachment.

I'm exporting these points as a mesh, and I want the highest resolution RGB image to project from a top-down view onto that exported model. I hope to clean up the exported RGB image and simplify it in photoshop, using it as a guide to paint the surface, keeping only the details relevant to my project.

I tried to use the "rasterize" function to have CC export an RGB image of the lowest points on the cloud (basically the road and street surface). I want an orthomosaic type of image that represents the RGB colors captured in the scan. You know, parking lot lines and crosswalks and the asphalt texture, etc. I can't for the life of me find the way to do that. I used "RGB" and "image" options, but all can manage to export is a brightly colored image of the scene that is of no use to me, and looks nothing like the on-screen top view image that I have attached.

Thanks in advance!

Which version of CC are you using?

And are you exporting the raster as a 'Raster' (geotiff) or as an image?

If you export as a raster (geotiff), you can explicitly choose to export the 'RGB colors'. Then, make sure the program you load the tiff file properly handles this format (some programs only handles very specific types of tiff files).

And if you export to a simple image, then make sure the 'active layer' is 'RGB' before doing so.
