Introduction

Use this guide when doors along your scan route cannot be propped open in advance and you'll have to open them yourself mid-scan. You'll need a free hand and a clear approach path. By the end, you'll know how to pass through doorways without breaking SLAM.

Before You Start Scanning

1. It is best if you can open doors in advance and keep them open during the scan. This reduces the chance of SLAM errors and helps you get the best possible mapping result.

1. If these options are not permitted, note which doors you must open yourself while scanning. If possible, have another person accompany you and open doors for you during the scan.

2. Remove trip hazards near doorways.

3. Follow all fire‑safety and access rules before you keep a door open.

Best practices for managing doors while scanning

Caution: Avoid a collision with the door frame as you move through the door.

1. Approach the doorway

1. Slow down before the doorway.

2. Gently turn your body so NavVis VLX has visibility to:

   • The door frame

   • Nearby walls and the change in floor surface at the doorway

   • Textured details such as signs, hinges, or handles

2. Open the door

1. Stand close to the side with the latch, with your back toward the door.

2. Keep NavVis VLX facing the walls and other fixed features you used as reference.

3. Open the door slowly, just enough so you can pass through safely, then open it wider as needed. Avoid fast movements.

4. Keep your arm low and out of the field of view of the bottom sensor as much as possible, so the sensor mainly sees static features instead of your moving arm or the moving door.

3. Move through the doorway

1. When the door is fully open and not moving, walk through the doorway at a steady, normal pace.

2. Avoid abrupt movements or sudden turns while you pass through the frame.

3. Keep NavVis VLX aimed at the door frame and nearby walls until you are fully in the new room.

4. When you are fully inside, return to your normal scan speed and path.
