NavigatorIM AR

NavigatorIM AR is an industrial spatial-layout and training workspace for supported ARCore Android phones. It uses printed multi-face ArUco reference carriers together with calibrated tools or selectors to register points in a reference coordinate system and visualize geometry over the live camera view.

Core workflows
• Guided P1/P2/D3/D4 registration with retained samples, means and P12/D34 axes.
• Free POI, surface-cloud and danger-zone point registration.
• Explicit Measurement Tip control: Tool Tip is the default; the user can switch to Selector Tip at any time.
• Live reference-space Tip X/Y/Z, target distance, radar, signed axis/plane guidance and closest danger clearance.
• One-tap Danger + capture plus edit, delete and reset controls for registered data and danger zones.
• Import/export of point data, complete sessions and supported 3D model formats.
• Local workspace persistence with user-controlled exports.

Stability and tracking
NavigatorIM combines multi-face ArUco pose estimation with sub-pixel corner refinement, short-gap Lucas-Kanade corner tracking and temporal presentation filtering. Raw metric poses remain separate from presentation smoothing for registration and geometry calculations.

Example uses
NavigatorIM can support supervised bench-top fabrication planning, drilling-layout training, fixture and jig setup, mock-up alignment, maintenance/repair visualization on isolated equipment, spatial teaching, reference-relative point collection and advisory keep-out-zone visualization.

Measurement source
Tool Tip is selected by default. If the chosen tool is not tracked or its calibration is not confirmed, numeric guidance pauses instead of silently switching to another source. Guided P1/P2/D3/D4 capture retains the configured selector, while Free POI, Danger and Cloud capture use the selected Measurement Tip.

Important limitations
NavigatorIM is not a certified metrology instrument, machine-control system, collision-protection system or safety device. Do not use it for patient care or safety-critical decisions. Keep powered equipment stopped and isolated while using the app. Verify marker dimensions, mounting, tool-tip calibration and final dimensions independently with appropriate physical instruments.

The AR PHONE build requires a compatible ARCore device, camera permission and the supplied printed marker/reference kit.
