The objective of this step is to retrieve the depth value for each pixel in the images and cameras that had previously been resolved by Structure From Motion. This can take a very long time depending on the resolution and number of images provided.
Note
Requires Meshroom/AliceVision version 2023.3.0. See https://alicevision.org/#meshroom for information on how to download.
