<p>Welcome to <a href="https://vggsfm.github.io/" target="_blank">VGGSfM</a> demo! | |
This space demonstrates 3D reconstruction from input image frames. </p> | |
<p>To get started quickly, you can click on our <strong> examples (the bottom of the page) </strong>. If you want to reconstruct your own data, simply: </p> | |
<ul style="display: inline-block; text-align: left;"> | |
<li>upload the images (.jpg, .png, etc.), or </li> | |
<li>upload a video (.mp4, .mov, etc.) </li> | |
</ul> | |
<p>The reconstruction should normally take <strong> up to 90 second </strong>. If both images and videos are uploaded, the demo will only reconstruct the uploaded images. By default, we extract <strong> 1 image frame per second from the input video </strong>. To prevent crashes on the Hugging Face space, we currently limit reconstruction to the first 20 image frames. </p> | |
<p>SfM methods are designed for <strong> rigid/static reconstruction </strong>. When dealing with dynamic/moving inputs, these methods may still work by focusing on the rigid parts of the scene. However, to ensure high-quality results, it is better to minimize the presence of moving objects in the input data. </p> | |
<p>If you meet any problem, feel free to create an issue in our <a href="https://github.com/facebookresearch/vggsfm" target="_blank">GitHub Repo</a> ⭐</p> | |
<p>(Please note that running reconstruction on Hugging Face space is slower than on a local machine.) </p> | |
