New AI method estimates food volume from egocentric video without scale reference

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method for estimating the volume of food from egocentric stereo video, eliminating the need for manual scale calibration or reference objects. This approach utilizes FoundationStereo for zero-shot stereo matching, SAM 2 for food segmentation, and TSDF fusion to create a 3D mesh of plated food items from a single stereo recording. By leveraging wearable devices with factory-calibrated stereo baselines and on-device visual-inertial odometry for camera pose estimation, the system achieves a mean absolute percentage error of 9.1% across five tested food items, paving the way for passive dietary intake monitoring. AI

IMPACT Enables passive dietary monitoring and could improve health tracking applications.

    Reference-Free Food Volume Estimation from Egocentric Stereo Video

    arXiv:2610.12735v1 Announce Type: new Abstract: Current stereo vision-based approaches for food portion estimation are hindered by the user burden of using a mobile phone to capture multiple images or placing a reference object in the scene for scale calibration. As a step toward…
