Euler - angles

Hello Board,
 
i have a sensor that sends angles (yaw, pitch, roll) as Euler - angles.
Does anyone have a DAC or VBS to transform them into "real world" - angles?
 
Thank you,
 
Heiko

Hi Heiko,

I don't have anything to make this tranlation, but it would just be a few Formula Calculator calls, which you could execute programmatically (VBScript) or interactively in the Formula Calculator dialog.

1) Yaw --> the azimuth angle (in the X-Y plane)

2) Pitch --> the vertical angle (from the Z axis)

3) Roll --> ??

What did you want to do with Roll, exactly?  What do you mean by real-world angles?  Do you want to plot this somehow?  Once you have Theta and Phi from 1) and 2) above, you could calculate the XYZ coordinates of the tragectory of the airplane and plot that as a 3-D line in DIAdem-REPORT.

Alternatively, check out NI-Insight, with which you can view the attitude of the airplane vs. time ("Airplane Control Visualization" example)

Hi Heiko,
 
perhaps this further information in Wikipedia is useful:
 
Check also out the DIAdem's Matrix-Vector Operations MatVAlgebr etc.

Hello,

 

thank you very much,

i found a way to transfor the angles and it seems to work well.

Best regards,

 

Heiko
