How does 3D scanning work?

3D scanning is a technology that allows you to capture the physical world and convert it into a digital model.

The process involves capturing multiple images of an object or scene from different angles. The iPhone’s camera captures these images, and specialized 3D scanning apps process them to create a 3D model.

There are two main methods of 3D scanning with an iPhone: photogrammetry and LiDAR scanning.

Photogrammetry works by taking a series of photographs of an object or scene from different angles. The app then analyzes these images and uses algorithms to calculate the position and shape of the object in 3D space. By stitching together these images, a detailed 3D model is created.

LiDAR scanning, on the other hand, uses a laser sensor to measure distances and capture depth information. The LiDAR sensor emits laser pulses and measures the time it takes for the pulses to bounce back.

This data is then used to create a point cloud, which is a collection of points in 3D space that represent the object or scene being scanned. The point cloud is then converted into a 3D model.

Both photogrammetry and LiDAR scanning have their advantages and limitations. Photogrammetry is more accessible as it can be done with any iPhone model, while LiDAR scanning requires an iPhone with a LiDAR sensor, such as the iPhone 12 Pro or later models. LiDAR scanning generally produces more accurate and detailed 3D models, especially for larger objects or scenes.
