General / Build Tiled Mesh Model: Null Point Cloud

« on: April 25, 2022, 05:49:42 AM »

Hi, I'm currently working with a LIDAR dataset, which I've meshed and textured in Metashape using the quick_layout.py script (metioned here: https://github.com/agisoft-llc/metashape-scripts/blob/master/src/quick_layout.py directly using ground station locations instead of using images for alignment). Problem is when I try to created a tiled model, it gives me a "null point cloud" error window and nothing else. I'm sure my region is set correctly and covers my whole model and dense cloud. I speculate perhaps the function expected a sparse cloud there? Would there be any solutions? Thanks a lot in advance.

General / Directly use LIDAR station positions to reconstruct mesh

« on: April 13, 2022, 04:17:26 PM »

Hi, I have a huge E57 file exported from Cyclone I'm trying to use to reconstruct a textured mesh, but I'm running into issues. It imports without errors, but only the estimated positions of the stations show up (the guy who gave it to me said they were already registered), and they are marked as unaligned, and no point cloud is visible. However, the depth maps are there. Is this expected behaviour?

It would be great to know if its possible to directly use the registered station positions to reconstruct the mesh or a dense cloud, without having to align them using the photo data, since some of the photos have already have the original markers masked out. I tried aligning them as is but the results are all over the place and it would be a lot of repeated effort to find the markers and align the whole dataset again. Would appreciate any help! Thanks.

General / Realign two existing aligned chunks together?

« on: March 23, 2020, 05:05:36 AM »

I have two large aligned chunks that were aligned (photos) seperately. Is there a way to merge them into a chunk AND optimize the camera positions as if they were initially aligned as a single chunk? Thanks.

Feature Requests / Linux Metashape unable to move pop up dialog boxes

« on: March 14, 2020, 06:22:41 AM »

This issue happens with progress dialog boxes as well as file browsers. Suprisingly, resizing these windows work, however it always centers the dialog boxes in the center of the main window. Is this expected behavior? Thanks.

Feature Requests / Hierachical chunk groups

« on: March 11, 2020, 05:28:28 PM »

It would be great to have the ability to group chunks together, which would be particularly useful in large reconstruction projects where smaller chunks are initially aligned, then merged together. Better yet, it would be great to also have the ability to align these super-chunks together.

General / Optimize merged chunk?

« on: March 08, 2020, 12:33:42 AM »

In metashape, after aligning and merging two chunks, the matches between the two chunks do not seem to be kept as tie points in the new merged chunk. Is there any way to keep the matches as tie points? I assume that it would allow all the cameras to be optimized further after merging, making a better dense cloud.

General / Disabled cameras used for chunk alignment?

« on: February 28, 2020, 04:03:05 PM »

During chunk alignment, it seems that the disabled cameras are also utilised, or at least it seems to be slower compared to when I deleted the disabled cameras completely. Is this expected behaviour?
