FAQs

How do you take good pictures in a meshroom? ›

Take images with a side overlap of 60% minimum and frontal overlap of 80% minimum. For each shot, move to a new position (or rotate the object). Do not take multiple images from the same spot. For better coverage, you can photograph an area multiple times in different acquisition patterns.

It is best to take the photos sequentially in a circle around the object. Start with a circle at a low angle, then do one more at a higher angle to capture the topmost surfaces. Aim for at least 50% overlap between each image; 60-80% is ideal.

Meshroom is a free, open-source 3D Reconstruction Software based on the AliceVision Photogrammetric Computer Vision framework.

Each node that produces 3D media (point cloud or mesh) can be visualized in the 3D viewer by simply double-clicking on it. Let's do that once the MeshDecimate node has been computed. Double-Click on a node to visualize it in the 3D viewer.

The image importer is based on OpenImageIO, so all formats supported by OpenImageIO can be imported to Meshroom. However it is recommended to use '. jpg', '. jpeg', '.

For photogrammetry software to process any point on your object, each particular point needs to be clearly visible in at least two photos. To ensure you've captured an object well, you need generally from 20 to 250 photos.

ISO: Grain in the image can cause problems with alignment and texturing, so it is helpful to keep the ISO as low as possible. An ISO setting of 100 is ideal, but if you need to use a higher ISO, avoid going past 800.

These days you will not find many regular cameras with less than 12 megapixels of photo resolution. For photogrammetry and many other photography purposes, 12 million pixels is enough. As long as all other image quality aspects are well controlled, and the technique is there.

The most common choice is a digital SLR camera. Point-and-shoot consumer digital cameras are common as well. Even cameras on mobile phones can be used in many cases. PhotoModeler can also work with photos taken with unknown cameras, providing there is some known information about the scene.

Meshroom/AliceVision

The basic interaction is about as simple as it gets. Drag and drop pictures into the Meshroom window, hit START and wait for the finished model. However, with Meshroom you can also peform Augmented reconstruction.

What is the difference between Meshroom and MeshroomCL? ›

Meshroom and MeshroomCL provide an interface to algorithms for reconstructing 3D models from collections of images. While the original Meshroom required CUDA to achieve accelerated performance, MeshroomCL adds components based on the OpenCL API and can run on a variety of GPU platforms (AMD, Intel, NVIDIA, etc.).

Meshroom are one of the most slow software and cant produce good results. I can recomment to try 3dZephyr at least, but best option are RealityCapture/Metashape.

Once the images are imported, you can click the Start button to begin processing. Even with a small number of images, processing can take several hours to process.

Meshroom is a free, open-source 3D Reconstruction Software based on the AliceVision framework. AliceVision is a Photogrammetric Computer Vision Framework which provides 3D Reconstruction and Camera Tracking algorithms.

So when adding a video file to Meshroom, the following Message will appear: “You need to manually compute the KeyframeSelection node and then reimport the created images into Meshroom for the reconstruction.” FFmpeg can be used for video file conversion. Input video files or image sequence directories.
