在eCompass中计算Xh和Yh

你好，
 
 
 要了解如何（第7页），请参阅:(附录A，第19页）。有（第22页），第一个等式：
 
 Mx2 =Mx1cosÏ+ + Mz1sinÏ
 
 相当于：
 
 XH = XM cos Pitch + ZM sin Pitch
 
 （第7页）和第二个等式：
 
 My2 = Mx1sinγsinÏ + My1cosγ - Mz1sinγcosÏ
 
 相当于：
 
 YH = XM sin Roll sin Pitch + YM cos Roll - ZM sin Roll cos Pitch
 
 （第7页）

Hello,


To understand how  (page 7) has been obtained see:  (Appendix A, page 19). There is  (page 22), where first equation:  

Mx2 = Mx1 cos � + Mz1 sin �

is equivalent to:

XH = XM cos Pitch + ZM sin Pitch

of  (page 7) and second equation:

My2 = Mx1 sin γ sin � + My1 cos γ - Mz1 sin γ cos �

is equivalent to:

YH = XM sin Roll sin Pitch + YM cos Roll - ZM sin Roll cos Pitch

of  (page 7).

谢谢回复。
 
 你已经实现了电子罗盘？
 我是一名学生，我想问你是否可以给我一个电子邮件联系人，询问有关实施电子罗盘的更多问题。

Thanks for the reply.

You have implemented the e-compass ??
I am a student and I wanted to ask if you can provide me an email contact to ask more questions about implementing e-compass.
