Does RC use the photos taken from the scanner to texture a model?

I have searched and can’t seem to find the answer to this question. If it has been answered and you have a link that would be helpful.

My question is that when using a LiDAR scanner, such as the FARO s70, to collect points and photographs and then register and color the points and export to .e57, does RC use the photos when texturing the model after the reconstruction phase? 

My current workflow. 

  1. Use FARO s70 to scan and take photos at different locations. 

  2. Process the scans (align and color points) in Scene.

  3. Export ordered .e57 files. 

  4. Import into RC and align. 

  5. Reconstruct.

  6. Texture. 

During the texturing process. Is RC using the photos that are included in the .e57 files to texture or is it using the colored points? 

 

Thanks,

Shane

Hello Mr. Reynolds 

If you don’t import the photos from scanner, then it is the colored points being used.

Hello Erik,

The scanner captures images and then stitches them into a panoramic image to use to color the points. When I export the registered scans as .e57 files, I was under the impression that RC is using the images that are included in each .e57 file. 

Are you saying I need to manually import the images taken by the scanner (not the panoramic image) and try to get those to align with the point cloud in RC using more of a photogrammetry method? I have looked at the images the scanner takes, before they are stitched into a panoramic image and they are just narrow images with the scanner itself taking up most of the photo. There would be almost no overlap between those images.

Hello Mr. Reynolds,

RC creates multiple images from the color points stored in the .e57 file when converting them to the LSPs. So basically when you are texturing your scan in the RealityCapture it already uses images cut from the “panorama”. You can check those images after drag and dropping the LSPs from 1Ds window to 2D.
