提升AR增强现实定位功能
（映维网Nweon 2023年12月14日）在日前发布的一份支持文档中，苹果表示自iOS 17.2开始将开始收集地图相关的数据，从而提升AR增强现实功能的速度和精度。
在名为《Help improve Augmented Reality Location Accuracy in Maps/帮助提高地图中的增强现实定位精度》的博文中，苹果正在呼吁用户为在使用AR功能时与苹果分享周围环境的数据，从而帮助提高苹果地图中增强现实功能的速度和精度。
当你在苹果地图使用增强现实功能时，你可以举起iPhone来扫描你周围的环境，并从附近的建筑物和其他物理特征中检测特征点。
苹果指出，当你使用增强现实功能时，相关照片不会发送到苹果或存储在设备，系统只会收集相关的数据。相关特征点会以一种人类无法读取的方式进行检测，而且iPhone摄像头会过滤掉移动的对象，比如人和车辆。苹果地图只需要周围静止对象的特征点数据。
另外，苹果收集的数据会加密，不会与单个用户或Apple ID相关联。苹果同时会向数据添加“噪点”以添加不规则的变化，从而防止从数据重建图像的可能性。
你在任何时候都可以开始或停止共享你的数据，从而帮助提高增强现实定位的准确性。
打开设置应用程序。
点击隐私和安全，然后点击分析和改进。
打开或关闭“提高AR定位精度”。
在隐私和安全设置中，你可以选择与苹果共享数据，以提高AR定位准确性等功能。
