Hello Gusson,

Do you observe similar problem in Metashape 1.7.3?

The GPU and driver could be just too old for Metashape requirements.

Hello Elmar,

Please try to switch to OpenCL implementation by creating main/gpu_enable_cuda parameter via Advanced Preferences -> Tweaks dialog and setting its value to false.

Alternatively, you may consider building mesh directly from the depth maps data using Ultra High quality (skipping dense cloud and refine mesh operations).

Hello ruyi7952,

Thank you for sharing sample data.

We were able to track down the issue with the first camera being skipped, the problem should be fixed in the next 1.7.4 update.

As for the distortion parameters conversion, the distortion models used in Metashape and Inpho are different, so the transformation is performed numerically to achieve the closest output possible, therefore the coefficient values and their number may be different.

Hello Sami26beniaouf,

Just to clarify, do you want to create a mask on the image based on these coordinates or to create a 3D shape (polygonal)?

Hello ruyi7952,

Can you please send Metashape project with the alignment results (processed in 1.7.3 or 1.7.4 version) to and any additional data (like Inpho project files for import), that can be used for checking the reported issues?

Hello Jorge,

Metashape doesn't support direct import from the data saved in DIMAP format, it is recommended to convert the data to Metashape supported format using gdal_translate as described on page 23 of Metashape Pro manual:

The .txt files that you have in the directory are just copy of .xml files related to DIMAP data and do not correspond to expected rpc.txt format.

Hello mcstieg,

Please try to define .coo as center of orbit (i.e. the point of interest), .mag and .rot.

Hello Andy,

If you can share the sample dataset (images) and the project processing results in 1.6 and 1.7 versions, where the accuracy difference can be observed, please send the download link to, so that we could analyze the internal behavior and investigate the reason of the observed difference.

Hello Elmar,

Can you please check, if the procedure can be completed when only single GPU is selected at a time in Metashape Preferences?

If the same behavior is observed, I would ask you to send the project with alignment results and mesh model to, so that you could check additional details.

Hello neo571,

Would it be possible to share the example of problematic images to You can use any convenient file transfer service to send the data to us.

Hello Elmar,

Which NVIDIA driver version is installed on your machine?

Hello Andy,

Does it help, if you change the way of doc definition and use the following:
Code: [Select]
doc = Metashape.Document()

Also you may need to define the path relatively to "root" in createBatch command.

Hello CheeseAndJamSandwich,

It can be said, that Align Photos operation contains of two major steps:
1. Image Matching
2. Camera Alignment

Image matching stage starts with the feature points detection. The time spent on this task mainly depend on the Keypoint Limit parameter value and image dimensions. Then goes matching itself (may include the pre-selection sub-step). The time spent on this stage depends on the number of detected keypoints, number of images and pre-selection method used (also the excessive image overlap may slow down the process).
Camera alignment timing mainly depends on the number of images, number of calibration groups, number of detected tie points.

Hello Jamin,

Good to hear that the issue has been resolved.

Each task in the batch will be assigned to Metashape version related to the first node assigned to this task. After that only nodes with the same version installed may continue working on the given task. It has been implemented to avoid version mismatch issues, but provide the possibility to use nodes with different Metashape versions.

Version number assigned to the current task can be checked in the upper frame of Agisoft Network Monitor dialog, which contains the list of batches.
