可以通过智能手机GPS定位我们的哪个楼层？ [英] Can be located which floor we are via smart phone GPS?

问题描述

有没有办法可以通过智能手机来决定我们的楼层？

例如，我在一幢大楼里。第5层;

我的智能手机中的原生应用程序可以在5楼知道即时消息，并向我提供有关5楼（导航到1楼）的建议。

使用一些较新的Android手机（例如三星Galaxy S3），嵌入式气压传感器可以用来获得准确的室内高度估计值，这可能会导致（假设你知道地板位于哪个高度）。

请参阅关于STMicroeletronics压力传感器的文章：

此应用程序显示基于气压的高度：

以下是Android API：

Is there a way that can decide which floor we are via smart phone?

For example, i m in a building. floor 5;

the native app in my smart phone can know i m on floor 5 and give me some advice about floor 5（navigation to floor 1）

解决方案

With some newer Android phones (e.g., Samsung Galaxy S3), embedded barometric pressure sensors can be used to derive an accurate indoor altitude estimate, which could be transformed into floors (assuming you know which elevation the floor is located at).

See this article on STMicroeletronics pressure sensor:

This app shows altitude based on barometric pressure:

Here's the Android API: http://developer.android.com/reference/android/hardware/SensorManager.html#getAltitude(float,%20float)
