手机传感器建筑测量实用算法与思想

Practical algorithm and idea of mobile sensor building measurement

通过对手机传感器进行分析,从认识手机传感器、手机坐标系与惯性坐标系的比较以及如何实现手机测量等方面进行了论述,提出了利用手机传感器建筑测量的算法与思想。通过手机中自带的陀螺仪传感器获取手机绕某一坐标轴(此坐标轴为手机特定的坐标轴)旋转的角度值,额外测量得到手机在平面空间移动的距离,经正、余弦定理进行换算即可得到测量值。

Through the analysis of mobile sensor,the comparison of mobile phone sensor,mobile coordinate system and inertial coordinate system and how to realize mobile phone measurement are discussed,and the algorithms and ideas of building measurement using mobile sensor are put forward. The value of the mobile phone’s angle of rotation around a coordinate axis（this coordinate axis is specific coordinate axis of the mobile phone）is obtained by using the gyroscope sensor in the mobile phone. The distance of mobile phone in the plane space is measured,and the measured value can be obtained through the conversion of the positive and cosine theorems.
