This article explains the reason why a project may have failed processing with PIX4Dcloud.
Information: If the problem is related to the display of the outputs and not the processing (the outputs are generated but something in the display doesn't work or no email is sent as error notification), please visit: Output is not displayed / feature is missing in the cloud.
Project failed due to a crash in our servers.
When a projects fails to be processed in our servers, it is usually due to lack of resources. This can happen if the project is too large or the processing effort exceeds PIX4Dcloud servers' capabilities.
If the project was processed directly on PIX4Dcloud:
- Create a new project with a reduced number of images.
- Draw a region of interest in PIX4Dcloud to reduce the area to process.
If the project was uploaded from PIX4Dmapper or PIX4Dmatic to be processed in PIX4Dcloud, then try choosing at least one of the following options:
- Reducing the quality of outputs to be produced (e.g. decrease the density of the point cloud, define a smaller pixel size for the ortho...)
- Reducing the number of images. Sometimes there are flying modes in some drones which capture more images than necessary to cover the area or sometimes, the images are covering a larger area and some of them can be skipped.
- Ensuring the strictly necessary outputs are marked for their generation.
- Defining a processing area
Information: We recommend to see the PIX4Dcloud best practises article to understand how to work and what to expect from PIX4Dcloud.
Warning: PIX4Dcloud allows users to process projects with minimum 6 images and a maximum of 4000. However, a project with less than 4000 images may fail. This is particularly true when using large format cameras (42 MP or more) or projects with a lot of overlap (oblique flights).
Project failed due to wrong inputs
A project may fail due to wrong inputs: images, ground control points and coordinate systems).
In this case, we recommend the following checks:
- Verify that the image quality is sufficient. For more information: How to verify that the Image Quality is sufficient.
- Verify that there is enough overlap between the images. Fore more information: How to verify that there is enough overlap between the images.
- Verify that the image geolocation, output coordinate system and Ground Control Points / Check Points coordinate system is correct. Learn How to verify all of the coordinate systems in PIX4Dcloud
Information: It is also recommended to review the Quality Report that is usually available in the email that is sent after the process has finished.
- To analyze the Quality report, see this article.
