SAM 3 & SAM 3D Explained: Next-Gen Image Understanding & 3D Reconstruction

SAM 3 and SAM 3D: A Practical Guide to Next-Generation Image Understanding and 3D Reconstruction Understanding what appears inside an image, identifying objects, tracking movements in video, and reconstructing the three-dimensional structure of the physical world have always been core challenges in computer vision. Over time, tasks such as object detection, segmentation, tracking, and 3D reconstruction have often evolved independently, requiring different models, annotation methods, and technical expertise. With the introduction of Segment Anything Model 3 (SAM 3) and SAM 3D, Meta presents a unified set of models capable of bridging these tasks across two and three dimensions. Together, they …
