We recommend using "3D scanner app" on medium sized objects (0.5m to 5m in width) for best quality.  The other details are:

• "HIGH RES" mode:

  - Max depth: 1 to 1.5m

  - Resolution: 5 mm

  - Confidence: high (use of highest quality data input)

  - Masking: none

• Walk slowly and consistently when scanning, ~0.5m perpendicular to areas where you want the best texture quality. Keep in mind the texture used to color the model is generated from the video feed while you are scanning. Note: If there is a big difference in the quality of the applied texture in the same scan, it is often caused by moving fast vs slow, and scanning close vs far in the same scan.

• The most precise resolution the iPad pro can scan is around 5mm. This means you can expect the mesh to be precise up to ~1cm. If higher precision is needed, especially with polished surfaces, we recommend using a professional scanner.

The Alternative - Artec Professional Scanner

• • • You can make a choice based on the precision, speed and subject size needed with Artec Professional Scanner. Check out: https://www.artec3d.com/portable-3d-scanners

    • The main price difference between the iPad (consumer product) and the Artec devices (professional scanners) is based on their accuracy. 

Difference - Scanning with iPad and Artec Professional Scanner

• • • iPad: accurate up to ~ 5mm

    • Artec: Some devices are accurate up to ~ 0.05mm (i.e. up to 100 times more accurate. Which makes all the difference when scanning small parts like cables, screws, etc.) However, the iPad pro is often a great start to explore the possibilities of LiDAR scanning and can cover a large amount of use cases for creating work instructions.
