Hi there, I would like to share my experience creating this model. You can use it as an example for your 3D modeling challenge submission.

How I created it:

  1. I used my smartphone to capture a video of the bear.
  2. I created a project using Pix4Dmodel on my laptop.
  3. I extracted images every 3 frames.
  4. To have a fast overview of the project and assess the quality of my dataset, I ran only step 1 in “rapid” mode. Once the initial processing was ready, I defined the processing area and adjusted the orientation.
  5. Before uploading the project to the cloud, I went to the processing options and changed the settings to get a visually appealing mesh as result. I loaded the “ 3D Models ” template. Then I ticked the “Use Geometrically verified Matching” in the matching settings.
  6. Once I defined all the settings, I made sure I selected both, “Initial Processing” and “Point Cloud and Mesh” steps in the processing dashboard, and uploaded to the cloud for processing.

This is the link to my project on the Pix4D cloud:

Have fun creating and sharing your own project!


This brings up a big point for a lot of us.  In most of our work the default cloud settings don’t make a good enough project so the desktop is the only way to work.  But the desktop doesn’t have a good means of displaying our work without giving up the entire Pix4D project folder and thus revealing trade secrets.

I look forward to participating in this challenge but we need some more options in the cloud processing or a hosting site for desktop projects would be a great addition to the Pix4D system.



@Adam: A project that gets uploaded to the Cloud from the Desktop software will keep the same processing options, that is currently the recommended workflow if you want to do more advanced modeling on the Cloud. An example is point 5) from Veronica’s comment.

At the moment it is possible to upload the Orthomosaic and DSM as result file directly on the Cloud. I know the Cloud team is working on extending this to more result files. I encourage you to share your feedback and suggestions in the Product feedback or Cloud web platform topics of the community, so that it is not hidden in this challenge post. 

Let’s keep the comments section for project submissions. :slight_smile:

Looking forward to seeing your model submission Adam!
