Validating Floorplan & Sensor Location Accuracy Background

Background

At times floor plans do not accurately represent the reality, workpoints are in different locations and it’s difficult to measure sensor locations correctly. 

In addition, there might be line of sight obstructions that are not captured on a floorplan that could interfere with XY Sense sensors ability to functional correctly.

Fortunately, from iPhone 12 and above, there is a cost effective, easy solution to validate floorplan and sensor location accuracy.

Equipment

1. iPhone 12 and above (iphone 14 pro recommended)
2. 3D Scanner App (Download app from https://3dscannerapp.com/)
3. Recommended: Gimbal to minimise drift. Eg https://www.dji.com/au/osmo-mobile-6

Instructions

Open the 3d Scanner App
From the bottom right button menu choose LiDAR
Hit the red record button
Additional Instructions Slowly pan around the space you're capturing - you'll see that the space will go from red to coloured & textured once it's covered. Aim to not have red above any key objects (desks, tables), and walls (without glass) As it's laser - it won't show up on windows / glass / mirrors so try and scan the edges of those objects instead The app may crash after scanning a large amount of spaces and may be subject to drift so keep scanning sections to 2000 sqf / 180sqm
Once you've completed the scan hit the red button to stop and then hit Start with the following settings. Once you’ve finished
To export the resulting image as a top floor plan:
Choose Share
Choose Floorplan Image
Choose the following settings: Rotate Model - rotate for orientation to make sense and fine tune (+- 1º) to align a wall to be straight Format - PNG or JPG Background White Resolution 4k Overlay X-Ray Mesh Opacity 50% Height slice - you can edit this to optimise - needs to be under the ceiling height and above the desk height Resolution 4k If captured correctly - this floorplan can be used to validate existing floor plans as it’s a scale diagram +-5cm accuracy. The best way to do this is to overlay this on top of an existing floorplan in a tool like Pixelmator or Photoshop with 50% opacity. You’ll be able to see where the discrepancies lie. Alternatively - you can send it to the XY team for analysis.
To export the 3d point cloud to confirm line of sight obstructions and allow 3d walk throughs
At the bottom of the app, click share
Choose Point Cloud
Choose: High Density XYZ color and Zip Files
This will create a file and allow you to email / save / AirDrop From here a 3rd party will be able to navigate through the virtual 3d point cloud you’ve created, do measurements, and validate the space for ideal sensor positioning and measurement.
