3D传感

使用艾迈斯欧司朗微型摄像头、红外照明器和传感，实现6DoF 位置跟踪、边界检测、3D 场景重建、视频透视、手持控制器和手部跟踪功能

探知现实世界的传感技术对于虚拟现实（AR）和增强现实（VR）至关重要

VR 头戴设备和 AR 眼镜如何获取自身位置和用户移动信息？虚拟物品如何放置在现实世界以实现逼真的效果？

探知现实世界的传感技术对VR 和 AR 应用体验至关重要。艾迈斯欧司朗提供了全面的传感产品组合，包括图像传感器、微型摄像头、红外 LED、IR VCSEL 模组、照明器驱动和集成 dToF 范围传感器。

沉浸式 VR 体验需要对头戴设备的运动进行精确的6DoF跟踪。当用户头部在运动时，能够自然地渲染并将虚拟场景画面显示给用户。同时，必须设置活动边界以避免用户碰撞。

AR 体验需要进一步对周围环境进行 3D 地图建模，以便在现实世界设置虚拟场景并实现逼真的现实效果。VR 视频透视（VPT）还必须重新渲染完整的场景，在闪烁、环境光和颜色传感的作用下效果更佳。

手部跟踪是关键的用户交互方式，无论是否使用手持设备；通常使用同样的探知现实世界的跟踪传感器实现。

FAQ

How do devices understand the world around them? 

3D sensing provides real-time distance and depth information, enabling devices to recognize objects and understand spatial relationships.

Why does depth information matter? 

Depth information allows devices to move beyond imaging and become aware of their surroundings, enabling more intelligent and immersive experiences. 

Which applications use 3D sensing?

Scene reconstruction, spatial mapping, autofocus, collision avoidance, object detection and gesture-based interaction.

What technologies are used for 3D sensing? 

Depending on the required range, accuracy and power consumption, systems can use direct Time-of-Flight sensing, active illumination and camera-based depth technologies. 

Why choose ams OSRAM for 3D sensing? 

A comprehensive portfolio of dToF sensors, VCSELs, infrared emitters and driver solutions designed for compact, power-efficient and high-performance wearable devices.
