#spatialcomputing

3D real-time measuring/scanning the object surfaces is now democratized, e.g., Apple #LiDAR, NVIDIA instant #NeRF.

3D real-time understanding is the next step.

Application fields include #AR #MR, #AutonomousVehicles , #robotics, #AEC, #BIM, #Ads, ...

A geometric object in 2D/3D space has shape, size, position and rotation.

The human visual intelligence can detect/identify easily the shape of a geometric object in 2D/3D space, but cannot measure exactly the size, position and rotation in mm accuracy.

Purposefully, we use measuring tools and data processing software.

The AI/ML/DL emulates the human intelligence, and thus inherits the limit of human intelligence.

The currently popular AI/ML/DL must be for detecting/identifying, but not for measuring/processing the geometric objects in 2D/3D space.

It is a video that can only be filmed and produced using the following two techniques.

1. Apple technology to check the movement of the iPhone recording the video in real time (including its current location and direction). Google and Microsoft have it too. That means everyone has it.

2. CurvSurf technology to check the shape, size, position and orientation of an object in front of the iPhone in real time. It's a capability that the aforementioned big IT companies don't have. That means only CurvSurf has it.

Locally differentiable surfaces can be classified as one of the 4 surface types:
- planar
- parabolic
- elliptic
- hyperbolic.

Most man-made object surfaces are composed of planes, spheres, cylinders, cones, and tori:
- Plane is planar
- Sphere is elliptic
- Cylinder is parabolic
- Cone is parabolic
- Torus is locally elliptic, hyperbolic, or parabolic (seldom).

Then, through the local curvature analysis of the point cloud measured, we can assume the local shape of the measurement object:
- Planar --> plane
- Parabolic --> cylinder or cone
- Elliptic --> sphere or torus
- Hyperbolic --> torus.

By investigating the shape parameters of cone (vertex angle) and torus (mean and tube radius) fitted to the point cloud measured, we can refine the object shape between sphere, cylinder, cone, and torus.

Automatic recognition and measurement of sphere, cylinder and torus

Sphere, cylinder and torus can be automatically recognized and measured through torus fitting to the measurement points of object surfaces.

- Sphere is a special case of torus with zero mean radius.
- Cylinder is a special case of torus with infinite mean radius.

From the 3D measurement points (point cloud) obtained using a 3D measuring tool/equipment such as the iPhone/iPad Pro LiDAR 3D camera, FindSurface is recognizing and measuring:
- planes (plane, box)
- ring donuts (sphere, cylinder, ring)
- cones (cylinders, cones).

Furthermore, FindSurface includes undisclosed built-in functions finding:
- linear, circular, and elliptic cross-sectional shapes
- conic section (ellipse, parabola, hyperbola) shapes.

Finding boxes has a potentially large market size and therefore an immediate release term.
