Hi! Thank you for this awesome 3D reconstruction software! I am new to Meshroom and I have a couple of questions. I used Meshroom to generate a 3D model from a set of photos. I am in need of rendering the generated model from specific camera poses (the same camera poses as the input images used for generating the 3D model). Could you provide me please some guidance on how I can achieve this? Can this be done directly in Meshroom? Thank you in advance for all your help! |

Here is an example from the Tanksandtemples dataset in Meshroom 2023.3:
You can overlay source image and reconstruction. Click through the Image gallery to align each image. You could also use Blender with this addon: https://github.com/SBCV/Blender-Addon-Photogrammetry-Importer |

Hi! Thank you very much for your reply, it is very useful. Could you tell me please how I can save, if possible, the reconstruction images in the MeshroomCache folder? Thank you again for your support, it is highly appreciated! |

Sorry, I don´t understand what you mean with "reconstruction images". Those are your input images as seen in the Image Viewer. |

"some of the camera parameters are off" -> I am not so familiar with Blender myself, but you should be able to create a camera with real parameters from the parameters in the metadata of your original images. Do you use the original images or the undistorted images? "Is there any way to save images directly from the 3D Viewer in Meshroom?" -> No. The 3D viewer is based on https://github.com/alicevision/QtAliceVision if you want to check out the code. Saving the view as image could be nice contribution. |

Thank you @natowi setting the parameters from the metadata of the original images resolved the issue. |

Maybe check out https://github.com/tibicen/meshroom2blender as alternative? (not sure if it works with the latest release)
