iPhone LiDAR: Beyond the Camera's Eye
8 Sep
Summary
- LiDAR uses light pulses to measure object distances and shapes.
- It enhances augmented reality apps with spatial awareness.
- LiDAR improves iPhone camera performance in low light.
The LiDAR sensor on iPhones operates discreetly, without a dedicated app or setting. Instead, it functions in the background, providing depth information when needed.
This technology, known as "light detection and ranging," emits invisible light pulses. By measuring the return time of these pulses, the iPhone accurately determines the distance and dimensions of nearby objects.
While cameras show visual appearance, LiDAR adds crucial distance data. Apple's ARKit framework utilizes this to generate detailed 3D meshes of surroundings.
This spatial understanding empowers augmented reality applications. For instance, Apple's RoomPlan framework uses both camera and LiDAR data to map rooms, identifying features like walls and furniture.
Furthermore, LiDAR enhances camera functionality, especially on Pro models. It aids in capturing clearer Night mode portraits and ensures quicker autofocus in low-light scenarios.
