No layer is created using

International

Good afternoon,
For our project, we are using different layers to create different textures. Unfortunately, sometimes the layer is not created, so our second texture looks like the first one.
We are following the following procedure:

  1. We are copying images from drones to the “_texture01” folder.
  2. Locally we apply some transformation on the images.
  3. We save them with its metadata. We are using the python snippet to save metadata:
from PIL import Image
import piexif

img = Image.open(image_path)
if "exif" in img.info.keys():
      exif_data_bytes = Image.open(image_path).info['exif']
else:
      exif_data_bytes = piexif.dump(piexif.load(image_path))
       logger.warning(f"No exif was found for image {image_name}")
  1. We are saving the images with the same name in the folder “_texture02”.
  2. We send “_texture01” and “_texture02” folders to the Reality Capture
    Using the following algorithm, we are getting 2 textures: original and textures with transformations.

Do you have any ideas, what causes instability in the procedure. The images are coming from different drones and they might have different metadata. Are there any additional requirements, which prevent RC creating the second texture?

Best regards,
Ekaterina Senchugova

Hello Ekaterina
Do you have such case, when the texture 2 is not created? Are you able to check the layer in 2D view in such case? Are the images in the layers folder the same in the size? Is it possible that the images are imported as separated images and not a layer?

Sorry for a late reply.

The second texture is always created. We do see that the images get imported not as a layer, but as images with the same name, the same size and we use piexif python library to extract metadata. We import these images in the folder. That is why it works for the majority of the projects. But we still have some cases, where it does not work. For example, we have a problem with following image.
Do you have any ideas, what we might be missing, that Reality Capture map the images successfully.

I am looking forward to your reply.

Best regards

For me the images are imported as a layer.
I have them in separated folders:

image
image276×146 9.68 KB

And it is imported as one image:
image

with two texturing layers:
image

I can see that also in 2D view. I’ve tried to use also _geometry folder for the image and it worked, too.

So, I am not sure why it doesn’t work for you.
