Live Action Data Input / Output



      LADIO will create a central hub with structured access to all data generated on set. This will enable the post-production team to be part of the on-set dataflow, building on the momentum of editing and color grading that are already initiated directly on-set. It will also support digital visual effects (VFX), whose seamless integration between live action and computer graphics elements is even more demanding. LADIO will bring about a VFX paradigm shift by spending more effort on set to drastically improve efficiency, without intruding onto the work of the live action crew. The LADIO hardware and software will streamline the setup of all devices for data collection and monitoring, and track the location of all recorded data in time and space in a common 3D reference system. 3D acquisition of the set with a dedicated in-house pipeline is already a common practice for high-end productions. LADIO will improve and release new open source software libraries to foster interoperability and collaborations.

We love to test our algorithms with popular models, which are often considered as reference for datasets. Here are some examples gathered on our AliceVision's website with Sketchfab.

We have also collected dataset from a couple of film sets, comprising data for pointcloud creation and reconstruction, and several challenging scenes for camera tracking.

The original (and still growing) dataset can be found on, but you can take a look at the following previews.

Open Source

We build a fully integrated software for 3D reconstruction, photomodeling and camera tracking. We aim to provide a strong software basis with state-of-the-art computer vision algorithms that can be tested, analyzed and reused. Links between academia and industry is a requirement to provide cutting-edge algorithms with the robustness and the quality required all along the visual effects and shooting process.

The LADIO software builds on a set of core libraries, both newly written ones and such that are adapted from existing software. All of these core libraries are based upon open standards and released in open source. This open approach enables both us and other users to achieve a high degree of integration and easy customisation for any studio pipeline.

Beyond our project objectives, open source is a way of life. We love to exchange ideas, improve ourselves while making improvements for other people and discover new collaboration opportunities to expand everybody’s horizon.

Photogrammetric Computer Vision Framework

AliceVision is a Photogrammetric Computer Vision framework for 3D Reconstuction and Camera Tracking. The library scope is not limited to the creative sectors but can be used in a wide spectrum of fields, like urban planning, industrial design, archeology, medical applications, etc.


Scale-Invariant Feature Transform (SIFT)

This library provides a GPU implementation of SIFT.
25 fps on HD images on recent graphic cards.
