More than a rotating platform
The ASCAND coded turntable moves an object through a structured sequence of views while the camera remains fixed. Its visible patterned band is not decoration: it provides orientation evidence that ASCAND can use when interpreting captured frames.
This makes the turntable part of the acquisition system rather than a generic motorized display stand. It establishes a stable rotation axis, carries the object through changing viewpoints and helps connect recorded observations to their position around that axis.
Understand structured rotation
Rotation becomes usable evidence when its position can be interpreted
A video shows that an object is turning. Structured reconstruction also needs a reliable way to relate observations to the changing orientation of that object.
Controlled object motion
The platform rotates the object while the imaging device remains in a stable position. Instead of asking the operator to reproduce a smooth handheld path, the turntable creates a predictable acquisition relationship around one vertical axis. This makes setup, framing and capture behaviour easier to observe and repeat.
A visible orientation reference
The patterned band carries Gray Code: a visual code designed so successive positions can be distinguished reliably. ASCAND detects and interprets this band across captured frames, rejects or corrects inconsistent readings and reconstructs a continuous rotational sequence. Visitors do not need to decode the pattern themselves.
How Gray Code supports rotation reference
Observations in a shared coordinate system
Once a captured frame is associated with turntable orientation, its observations can be interpreted relative to the rotating platform. The turntable therefore contributes position information; it does not create geometry by itself. Geometry is reconstructed later from the visual, silhouette or optional laser evidence recorded during capture.
From physical rotation to indexed observations
1. Position the object
Place a suitable object securely on the platform. It must remain stable as the table rotates, and the surfaces needed for the intended reconstruction must be observable from the selected camera position.
2. Frame the capture area
Position the camera so the object, turntable and relevant coded band remain visible throughout rotation. Leave useful margins and check that no part of the object will move outside the frame.
3. Record with a fixed camera
Start the recording and let the turntable move the object through changing views. The camera remains still. Watch for vibration, object movement, focus changes, hard shadows, reflections or temporary obstruction of the coded reference.
4. Upload for processing
Upload the recording through the appropriate Scan Project. The acquisition pipeline extracts usable frames, detects the relevant turntable regions and interprets the coded sequence before the selected reconstruction method processes the available evidence.

A shared reference across ASCAND capture methods
The coded turntable supports a common part of ASCAND acquisition: understanding how the object was oriented when an observation was recorded.
In a vision-based workflow, changing views, silhouettes and other image evidence can be related to known positions around the turntable axis. In an optional laser-assisted workflow, the orientation reference helps place observations of the laser line into the shared turntable coordinate system. The reconstruction methods differ, but both depend on controlled acquisition and interpretable rotation.
The turntable does not decide which reconstruction method is appropriate, and it does not process a model inside its housing. Required camera support, optional laser hardware, calibration, current platform choices and compatible configurations must be considered separately.

The turntable controls rotation—not object suitability
Controlled rotation cannot make every object equally observable. Begin with an object that can sit securely on the platform without sliding, flexing or changing shape. Its position must remain stable from the first useful frame to the last.
Keep the object within the usable capture area and frame its full rotational envelope, including any protrusions or overhangs. A part that appears safely inside the image from the front may extend beyond the frame after half a turn.
Surface and geometry still matter. Reflections can change with angle. Transparent materials may reveal the background instead of a stable surface. Deep cavities, contact areas and downward-facing surfaces may remain hidden. Thin structures and visually ambiguous areas can also provide limited evidence.
A second scan in another stable orientation may expose surfaces that were hidden during the first capture. Multi Merge can then combine independently reconstructed models where the available geometry supports alignment. It cannot recover a surface that was never observed in any capture.
Use the verified current product specification—not the photograph—to confirm dimensions, supported load and compatibility for a particular object.

Make the acquisition relationship visible
Because the camera stays in one place and the object visibly rotates, the coded turntable makes cause and effect easier to inspect, explain and repeat.
Makers
Makers can adjust object placement, camera angle, lighting and orientation one variable at a time. The turntable provides a consistent physical reference for comparing captures while leaving room to experiment with preparation and complementary scans.
Education
Students can operate the capture process themselves and observe how viewpoint, silhouette, occlusion and stability affect the evidence available for reconstruction. The mechanism is visible enough to support discussion before results appear on screen.
Museums and shared workshops
Teams can establish a documented workstation for suitable replicas, teaching objects or approved artifacts. A consistent setup helps different participants follow the same capture logic without turning the equipment into a closed demonstration.
The coded turntable is one part of the capture system
The turntable rotates and supports the object while presenting a visible orientation reference. It does not hold the smartphone, record the video, upload files or reconstruct the model.
A usable capture setup also needs a suitable and stable camera position. The ASCAND Vision Capture Kit brings the physical vision-capture relationship together. The complete ASCAND system connects supported acquisition components with the processing workflows available through 3D-Scan.Online.
This distinction matters when ordering. A technical description of a component is not automatically a list of what is included in a current retail offer. Verify whether the coded turntable is being offered separately, as part of a kit or as part of another configuration.

Verify the current configuration
Before ordering, confirm the current product information for the exact configuration offered:
- Dimensions and object envelope: Verify the platform dimensions and the space available for the intended object.
- Supported load: Confirm the current supported load and any balance requirements.
- Motor, control and power: Check how rotation is started, controlled and powered.
- Included parts: Verify every supplied physical component rather than inferring contents from photographs.
- System compatibility: Confirm compatibility with the intended Vision Capture Kit, ASCAND configuration and optional extensions.
- Commercial terms: Review current price, availability, delivery region, returns, support and warranty.
