Adding Depth Maps Without Reprocssing

[KBL]

I'm trying to process depth maps for a subset of the images in my project. The following code identifies the positions of each image without a depth map successfully. However, when I run buildDepthMaps, processing finishes instantly ("Finished processing in 0 sec (exit code 1)") when reuse depth maps is set to false, or alternatively reprocesses from scratch when reuse depth maps is set to true.

Is there a way to reprocess depth maps for only those photos that do not have depth maps, or am I setting a value incorrectly in my script?

Code: [Select]

import Metashape

chunk = Metashape.app.document.chunk

# Get a list of the integer positions of each camera without a depth map

# Get all photo paths
allPhotos = []
for camera in chunk.cameras:
    allPhotos.append(camera.photo.path)

# Get photo paths without depth maps
photosWithDepthMaps = []
for key in chunk.depth_maps.keys():
    photosWithDepthMaps.append(key.photo.path)
 
# Get the integer positions of all photos
# not in the list of photo depth maps
photosWithoutDepthMaps = []
i = -1
for photo in allPhotos:
    i += 1
    if photo in photosWithDepthMaps: continue
    photosWithoutDepthMaps.append(i)

# Process those photos
chunk.buildDepthMaps(
    downscale = 2,
    filter_mode = Metashape.FilterMode.MildFiltering,
    cameras = photosWithoutDepthMaps,
    reuse_depth = False)

Hi KBL,

I think following code should do the trick:

Code: [Select]

photosWithoutDepthMaps = []
for camera in chunk.cameras:
    if camera in chunk.depth_maps.keys():
        continue
    photosWithoutDepthMaps.append(camera.key)
chunk.buildDepthMaps(
    downscale = 2,
    filter_mode = Metashape.FilterMode.MildFiltering,
    cameras = photosWithoutDepthMaps,
    reuse_depth = False)
Unfortunately, this process will create the new depth maps for photosWithoutDepthMaps while eliminating the already existing ones... Maybe Agisoft support can help on this ...

Much appreciated Paulo, unfortunately regenerating all the depth maps is what I'm trying to avoid. In fact, I believe you can entirely ignore the cameras parameter if you don't mind regenerating depth maps for all images. Hopefully Agisoft can lend their advice too!
