The creation of point clouds has become easier and more accessible. With devices such as the iPad or inexpensive scanners, the environment can be digitized quickly and cost-effectively. For more extensive and detailed projects, it is also possible to hire specialized service providers. This article focuses on how to create point clouds using an iPad.
LiDAR-Scanner in iOS devices
Current models of iOS devices (e.g. Pro and Pro Max models of the iPhone 12, 13, 14, and 15, as well as the third-generation 11-inch and fifth-generation 12.9-inch iPad Pro models from 2020 and later) offer the possibility to quickly create 3D models of rooms or objects thanks to an integrated LiDAR scanner.
Scanning-App
The free 3D Scanner App has already been tested by us. The described process & tips also work with other apps with slightly modified operation.
Scanning process
Preparation
- Clear the area to be scanned before scanning to achieve the best results.
- Avoid people in the scanning area.
Using the 3D scanner app
- Use "Normal" mode for most situations.
- For more complex structures, switch to "LiDAR Advanced".
- Start and end the scan with the red button.
Movement during the scan
- Move the device slowly from bottom to top, as if you were painting a wall with a paint roller, to fully capture each section.
- Try to scan each area only once.
- Also scan under and behind objects.
- Areas marked in red indicate where data is missing.
Processing the scan
- Process the scan via "Process".
- Start the editing process via "Edit".
- Select the "Crop with Box" tool under "Tools" to crop a section.
Export
- Select the "Share" button to access the export options.
- Select the Point cloud format.
- Make sure that "High Density" is selected.
- Set "Z axis up".
- Export it as "PTS".
- Transfer the exported file to your VR computer.
Further export options:
.glb files can also be exported from the above-mentioned 3D scanner app, which can be imported into the Halocline library directly via our CAD import.
