Can Pix4d handle it

PIX4Dmapper PIX4Dmapper Questions/Troubleshooting
1

Hello all,
I am new in Pix4d, the free trial period our company used is over and so far I am satisfied with the results achieved with this software.
There is a huge project in my company (about 10 000 photos at 21 megapixel) so I would like to know if Pix4dmapper (my company agreed to pay for it - first in a monthly basis in order to be convinced of the results) will be able to process that kind of project.
Computer’s specifications are as follows:

  • Windows 10
  • 128 GB RAM
  • AMD Ryzen Threadripper 3970X 32-Core Processor
  • GeForce RTX 2080 Super videocard

Tim, I’ve processed a project with 7,200 42mp images, which is 302 gigapixels, with Pix4DMapper. Your project is smaller (210 gigapixels). Your computer can handle a project of this size, but more RAM would be beneficial.

A couple of things to keep in mind when processing large projects:

  1. Turn off generate ortho mosaic preview in the quality report.
  2. Do not merge the ortho tiles or DSM tiles, as the system may crash. I use ArcGIS to create a mosaic dataset from the tiles.

Pix4D will be releasing a new product called Pix4DMatic soon, which is designed specifically for large projects.

Hi everyone,

Thank you, Andrew, for mentioning the launch of the new “large-project-friendly” Pix4Dmatic product! We cannot disclose too much at the moment, but the product will be available soon!

Tim, for Pix4Dmapper-related suggestions, I would recommend also checking the following community thread, where a lot of passionate users share their experiences and valuable insights in terms of large mapping projects: Experience with large datasets?

Best,
Teodora

Thank you, Andrew. This worked for me - now I have the ortho tiles and combined them with ArcGIS but when I export the combined orthophoto and open it, I’ve noticed that the quality is really bad. Do you encounter the same problem?

Pix4DMatic sounds interesting and I looking forward to the release

Did you create a mosaic dataset? If so you can export a single file mosaic raster by right-clicking on the mosaic dataset name in Catalog then selecting Export > Export to Different Format.

I created Raster Dataset and used Mosaic to new raster. I tried:

  • automatically exported combined file → result: low quality file
  • the file created from right click on the new (combined) layer → data → export data → result: can’t open generated tif in autocad (error: file not found or is not valid); can’t open it in photoshop (there is only one black rectangle)
  • the file created using Catalog → result: same as above
    I am obviously doing something wrong but I don’t know what
