Dense reconstrucion without GPU

[Albert Palomer]

Hello,

First of all, let me say thank you very much for such a useful tool. When I compile colmap I can not enable GPU support because I have Cuda 5 installed (i cannot update it until September). I have managed to create a project and load images to create a model (after adding the images to the database I run Processing->Feature extraction and Processing->Feature matching, and then Reconstruction->Start Reconstruction). View the attached file a.png for a screenshot of my model. After this I want to produce the dense reconstruction, for this I go to Reconstruction->Dense reconstruction. Here I select as workspace the folder where I have saved my model (a.png). Once the data is loaded into the Dens reconstruction window, I can press the Undistort button as well as the Stereo,I first undistort the images, then I try to run the Stereo but I get the following error message:

CUDA not supported (see attached file).

I have checked in options to see if there is any option to disable CUDA for this step but have not found it anywhere (all the other steps where not working untill I disabled the GPU). Can somebody help me build the dense reconstruction and mesh it?

Thank you very much.

Hi Albert,

Thanks for your feedback. Please refer to https://colmap.github.io/faq.html#available-functionality-without-gpu-cuda for information on how to proceed.

Let me know if you have further questions.

Cheers,
Johannes
