Cylindrical Bench Seat - Apple iPad Pro LiDAR

A large cylinder is extracted from the measurement points that cover only a small portion of the cylinder.
The virtual cylinder is well on the real cylinder.
The RMS error-of-fit is 3.6 mm.

Tools used:
- Apple iPad Pro LiDAR
- Apple ARKit 4
- Apple Metal API
- CurvSurf FindSurface Web.

An old prediction "AI/ML could learn and understand the basic geometric elements extracted from point cloud much more easily than the raw point cloud itself" is now confirmed through an academic research work,
S.-H. Cho, "Deep learning based 3D object recognition using geometric shapes and sizes”, Jun. 2020.

The App 'ARKitDepthFindSurfaceWeb' is not to be released to App Store by CurvSurf.

But, the source codes of the App 'ARKitDepthFindSurfaceWeb' are available on GitHub CurvSurf.

The source codes are under MIT license and App developers are allowed to use and modify the source codes in any ways and methods, and to release their own Apps.

The App 'ARKitDepthFindSurfaceWeb' is running on iPad Pro 2020 or iPhone 12 Pro (Max) with LiDAR 3-D camera.

The device of use must can access to the FindSurface Web API via internet.

The FindSurface Web Demo is a useful tool of learning the functionality of FindSurface Web API.

The current state-of-the-development in 3-D point cloud processing


We are living in 3-D reality, i.e., 3-D space.

The stakes are huge. Every movement, determination is performed in 3-D space. We see, feel, measure, analyze, decide, act and get.

The visual raw data of 3-D space are colors and depths (point cloud). Computer Vision is all about them.

The computer scientist/engineer are taming the raw data to the 'data structure' invented for computing machine, a bed of Procrustes.

Mesh and k-d tree are the typical data structure into which the raw data of 3-D space should be tamed to.

The raw data of 3-D space have to be processed and understood by vector & matrix, geometry, the proved tools of analyzing dimensional space.

AI may help fill the last gap.

The automatic (then, real-time is a matter of time) 3D reconstruction (meshing) is the state of the art; 2-3 scene/sec on mobile device.

Apple has now both technologies of multi-view photogrammetry and dToF.
Create 3D content with Object Capture


CurvSurf will show in 2021:
The real-time scene CAD-modelling on mobile device, 1 scene/sec.

3D point cloud, RGB image --> scene CAD-modelling.
