From Photo to 3D in 1 Second: How Apple’s SHARP AI Creates Real-Time 3D Scenes from a Single Image
6 days ago 高效码农Sharp Monocular View Synthesis in Less Than a Second: How Apple’s SHARP Turns a Single Image into Real-Time 3D “ Core question: Can one ordinary photo become a photorealistic 3D scene you can rotate in real time, without lengthy per-scene optimization? Short answer: Yes—SHARP produces 1.2 million 3D Gaussians in <1 s on one GPU and renders at 100 FPS with state-of-the-art fidelity. What problem does SHARP solve and why is it different? Summary: SHARP targets instant “lifting” of a single photograph into a metric, real-time-renderable 3D representation, eliminating minutes-long optimization required by NeRF-style approaches while improving visual quality over …
SAM 3 & SAM 3D Explained: Next-Gen Image Understanding & 3D Reconstruction
1 months ago 高效码农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 …
Depth Anything 3: How a Single ViT Achieves Metric 3D Reconstruction from Any Number of Images
1 months ago 高效码农Depth Anything 3: Recovering Metric 3D from Any Number of Images with One Vanilla ViT “ “Can a single, off-the-shelf vision transformer predict accurate, metric-scale depth and camera poses from one, ten or a thousand images—without ever seeing a calibration target?” Yes. Depth Anything 3 does exactly that, and nothing more. ” What problem is this article solving? Readers keep asking: “How does Depth Anything 3 manage to reconstruct real-world geometry with a single plain ViT, no task-specific heads, and no multi-task losses?” Below I unpack the architecture, training recipe, model zoo, CLI tricks and on-site lessons—strictly from the open-source …
