Hardware

|
|
We recommend using an iPad because of the sturdier grip, bigger screen, and better heat dissipation (scanning is hard work for your device!), but you’ll also be able to make a perfect capture with an iPhone. A gimbal is a good option when scanning with a phone.
A heavy-duty case is a good idea: You will be walking with your device and moving it around a lot so it's important to have it well-protected with a robust case with a good grip. A „pro” case will also make a good impression on the client or homeowner. |
One caveat
|
Make sure your case doesn’t trap the heat dissipated from the device. If you notice your device is getting too warm it is better to take the case off. Overheating can slow down performance but also lead to instability and inaccuracy due to the deformation of the optical elements.

Tags
|
|
To get the most precise results we cannot rely on the device’s sensors alone. After all, it's smart but it's only a phone!
Dot3D recognizes AprilTag targets. For a quick start, you can download and print them on a regular printer and use painter’s tape to safely attach them to a wall. Make sure not to occlude the black printed area with the tape. |
|
|
A sturdier solution: Mediatask provides a starter kit containing 28 targets printed on a lightweight gator board with blue-tack on the backside for easy mounting on and off the wall. The surface is laminated with a matte finish for durability and good detection at all viewing angles.
In the “place tags” section we’ll show you how to properly set up these tags, use your laser measure to grab reference dimensions between them, and input them into the app.
|
|
Other Tools
|
|
A laser measure tool will be essential for inputting additional known dimensions, so take your Disto with you. Versions with the end piece are most recommended as they will allow you to make even more precise measurements between the centers of the tags even at an angle.
|
|
It is handy to have a tape measure, especially when the only option is to measure between tags placed on the floor.
