OAK-D (Lite)

A small depth camera that combines stereo vision with an onboard AI processorprocessor.
The OAK-D can be used for 3D scanning because it produces RGB + depth maps that you can turn into a point cloud and mesh. You move the camera around an object or space, capture overlapping frames, and then stitch them together with software (Intele.g. MovidiusOpen3D, MyriadMeshLab, X)or ROS).

But: it’s not the preferred tool for 3D scanning.

    Accuracy is lower than LiDAR or photogrammetry.

    Shiny/transparent surfaces don’t scan well.

    Range is limited (~10 m).

    • How it works:

      • Two synchronized monochrome cameras capture slightly different views of the same scene.

      • Depth is computed by comparing the disparity (shift) between the two images.

      • An onboard neural depth engine accelerates the calculations, so the host computer doesn’t have to.

      • Optionally, an RGB camera provides color overlays on the depth map.

    • Key features:

      • Depth range: ~0.3 m – 10 m.

      • Field of view: ~70–80°.

      • USB-C powered, plug-and-play.

      • Runs AI models (object detection, face recognition, body pose estimation) directly on the device.

    • Why it matters for stereo vision:

      • Demonstrates that stereo vision can be compact, affordable, and real-time.

      • Doesn’t need external GPUs/CPUs for heavy lifting.

      • Provides a good bridge between basic stereo rigs (like DIY dual webcams) and advanced research hardware (like ZED cameras).

    • Use cases:

      • Robotics navigation.

      • Human pose tracking.

      • AR/VR prototyping.

      • Object recognition combined with depth.

      It’s great for real-time depth perception and robotics, but for high-quality 3D models you’d usually go with photogrammetry or LiDAR.
