How to Use Room Scanner in Live Home 3D for iPhone and iPad

Live Home 3D allows you to easily import a copy of your apartment into a project. This can be achieved with the help of the Room Scanner feature, available for iPhones and iPads equipped with a LiDAR Scanner.

So, how does it work? Room Scanner detects room surfaces and then creates walls in the app based upon this information. It allows scanning of the room walls with an accuracy of 97% up to 99%, depending on the illumination and size of the room.

The best scanning accuracy is achieved when an iPhone or iPad is placed 16 feet (5 meters) or less from the wall, and certain conditions are met.

In this article, we will elaborate on the room scanning process.

Activate Room Scanner

To start the scanning process, you need to stand in the center of the room, no further than 16 feet (5 meters) away from a wall. You can activate Room Scanner on your device via “Import > Scan Room in AR” in the Menu.

Start the Scanning Process

Now, begin scanning walls, starting with the nearest one. Move the device slowly to detect the wall surface.

You will notice that identified surfaces are automatically classified as a Wall, Floor, Ceiling, Door or Window.

Try to scan as much of the wall surface as possible, but it may be sufficient to scan a small part of a wall to get the result.

Removing the Pivoted Surfaces

Some parts of scanned surfaces may appear slightly pivoted, compared to the original wall; therefore, it is recommended to remove them from the Room Scanner consideration.

To do this, you need to first select such a surface on the screen. When it becomes highlighted in green, you can delete the pivoted area from the Room Scanner consideration by tapping on the trash can icon on the right part of the screen.

Also, when working with the Room Scanner, one can mistakenly select the wrong surface. In this case, just tap on the selected surface again. The selection will move cyclically along the adjacent surfaces until you reach the desired one.

Removing Additional Surfaces and Objects

During the scanning process, additional surfaces may also appear, coinciding with the same wall. In this case, it is recommended that you hover the device a bit longer next to such surfaces until the scanner combines them into one, or simply delete the redundant surface.

Another situation that can occur during the scanning process is that some of the furniture surfaces may end up mistakenly detected as a Wall. You should manually exclude such a surface from consideration by selecting it on the screen and tapping on the trash can icon when the surface becomes highlighted in green.

Start Over, if Necessary

If too many “erroneous” surfaces began to emerge, or the scanned surfaces began to “float” in relation to original walls, it is better to start over by tapping the “restart” button in the upper right corner of the screen.

Scan walls one by one while slowly turning and walking around the room. If the scanning of a wall does not start, or you are not satisfied with its quality, slowly approach the wall, but no closer than 2 feet (0.5 meters).

Finish the Scanning Process

Once you have scanned all the necessary walls in the room, just tap the Done button to complete the process. After that, Room Scanner will automatically create the rooms, based on the data obtained from the scan, and insert them into the 2D plan. The orientation of the walls will correspond to the True North if the device’s compass is calibrated accordingly.

Adjust the Room in 2D View

The scanning process is over, and now you are able to move the created room and adjust its walls on the 2D floor plan, if necessary. You can attach the room to the existing floor plan layout. Learn how to draw a floor plan in Live Home 3D.
