What is LiDAR scanning?
LiDAR Scan is an acronym for “Light Detection And Ranging”.
It is based on the time between the reflection of the laser beam and its return when taking a picture, and allows you to obtain information on the depth of the subject space and the 3D shape of the object.
All current iPad/iPhone Pro models have LiDAR function.
What is SAKURA3D SCAN?
It is a LiDAR scanning application provided by Japanese company Armonicos Co.

Functions common to mesh scan and point cloud scan
You can record your screen as a still image or movie during scanning or editing.
Turn on the light supplied with your iPhone/iPad to scan in the dark.
Functions about the scanned model
After scanning, you can use various functions by tapping the icons on the right.
|Init.Pos.||It returns to the front view of the scanned model.|
|Distance||Tap any point on the scanned model twice to measure the distance between the points.|
|Origin||Shows or hides the origin point.|

Renaming and Deleting a Scanned Model
You can change the name of a scanned model by tapping the icon next to the title in the main menu (scanned model list).
If you want to delete the scanned model, tap the trash can icon.
Outputting and Sharing a Scanned Model
The following extensions are supported by Sakura3D SCAN.
|Mesh scan models||stl, obj|
|Point cloud scan models||asc, txt, pts|
When you finish scanning or when you select one of the scan models from the main menu, you can choose the extension.
Select the desired extension from the bottom of the screen and tap the green button next to it.
The button will say “Export Mesh” for mesh scans and “Point Cloud” for point cloud scans.
Then, various sharing methods will be displayed.
You can export an unlimited number of point clouds once a day, but if the model is less than 500,000 point clouds/meshes 50,000 points, you can export an unlimited number of times.
If you want to output a model more than once a day and more than 500,000 point clouds/meshes 50,000 points, you should subscribe to the subscription because you are not covered by the free features.
You can choose to pay weekly, monthly, or yearly for the plan.
Tap on one of the plans to pay.
|Weekly Subscription||200 yen (10,400 yen/year)|
|Monthly Subscription||600 yen (7200 yen/year)|
