The specific user can control it by turning off the timing button on the mobile terminal. Calculate the moving distance of the mobile terminal from the time when the mobile terminal starts timing to stop timing. Since the moving distance of the mobile terminal is the length distance in the same proportion as the length to be measured, the moving distance of the mobile terminal is the distance of the length to be measured. The measured length is specifically displayed on the mobile terminal.
本发明实施例通过上述方式，一种测量长度的装置，将移动终端置于测量长度的开端，在开启计时以后通过移动移动终端，将移动终端沿着所要测量的长度方向上进行移动，由于移动终端移动的轨迹一比一于所要测量的长度，因此移动终端移动的轨迹就相当于测量的长度，当移动终端移动到测量长度的末端时，停止计时，根据移动终端移动的轨迹就可以得出所要测量的长度的具体长度数值，实现对长度的测量，同时通过移动移动终端的方式可以进行曲线等不规则长度的测量，如将移动终端沿着曲线所在的方向是进行移动，通过得到移动终端在曲线上移动的位移，得出曲线的长度，最终测量曲线长度，使得通过移动终端进行长度测量时更加方便和实用，并且同时可以测量曲线等不规则的长度的距离。The embodiment of the present invention uses the above-mentioned method to provide a length measuring device.
