Open Doors While Scanning - NavVis CLX

Use this guide when you encounter doors along your NavVis CLX scanning path that cannot be held open beforehand, requiring you to open them during the scan. You will need one hand free and a clear path to approach. By the conclusion, you will understand how to navigate through doorways without disrupting SLAM.

Before You Start Scanning

1. It is recommended to 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 you cannot prop the doors open beforehand, 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

1. Approach the doorway

1. Slow down slightly as you approach the doorway.

2. Hold NavVis CLX in one hand.

3. Keep the sensors aimed toward stable, fixed features such as:

   • 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 CLX 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 CLX 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.
