Problem with changing image paths to avoid reprocessing.

[March Castle]

I am having trouble using a workaround I thought could save me having to repeat the align, dense point cloud and mesh workflow stages.

I have an existing project which I have already fully processed all the way from alignment to generating Orthophotos. This was done using corrected images for data extraction.

Now I want to produce a second Orthophoto from the same set of images, but this time I want to use non-corrected images - i.e straight out of the camera.

I want to avoid repeating the align, dense point cloud and mesh workflow stages, and as the images are essentially identical I thought this could be easily achieved by substituting the uncorrected images for the corrected ones in the existing file and simply repeating the 'build Orthophoto' and 'generate Orthophoto' stages.

I have tried using the 'change path' command to update the filepath from the corrected images to the non-corrected versions.

This seems to work, except for the fact that some of the images are a different orientation within the set - i.e a mix of portrait and landscape. So despite being the same resolution, the portrait images are being flagged as missing (reason: resized) when I attempt to initiate 'build orthomosaic'

I have tried rotating the portrait images in Photoscan, but the problem persists.

Strangely, the image shows as being portrait in the 'Photos' pane, but is landscape in the main window. If you rotate the image 90 degress, then it appears to be landscape in the 'photos' pane, but portait in the main window.

Is there a workaround for this problem?

Thanks for your help.

Hello March,

The preview of the images in the Photos pane and default orientation of the image in Photo view mode is based on the EXIF orientation tag applied. If you use rotate image option in Metashape it would not affect the source images, so basically you just change the visual representation of the image.

I think that you should rotate the original images in the source folder by 90 degrees (use the same rotation direction, as it has been applied in the first project, for each image).
