Yaw Pitch & Roll to spherical Theta & Phi

Click For Summary
SUMMARY

The discussion focuses on converting Yaw, Pitch, and Roll angles into spherical coordinates Theta and Phi using smartphone orientation sensors. Participants emphasize the importance of defining the orientation of the spherical coordinate system in relation to the axes of Yaw (Z-axis), Pitch (X-axis), and Roll (Y-axis). A clear understanding of these relationships is crucial for accurately calculating the smartphone's normal vector projection. The conversation highlights the need for precise definitions to facilitate the conversion process.

PREREQUISITES
  • Understanding of Yaw, Pitch, and Roll concepts
  • Familiarity with spherical coordinate systems
  • Knowledge of smartphone orientation sensors
  • Basic trigonometry for angle conversions
NEXT STEPS

hi guys,
can someone please tell me how to find Theta and Phi from Yaw Pitch and Roll?
I use my smartphone orientation sensor on a project and i need to calculate the smartphone's normal vector projection.

First you must tell us how you want to orient the spherical system in space. Then maybe the question can be answered.
 
sorry but what do you mean by "orient the spherical system in space"?
 
Do you want the polar axis to represent your roll axis, or perhaps your yaw axis? Define how the polar coordinate system is to be related to the roll, pitch, and yaw axes.
 
oh sorry,
yaw is around Z axis
pitch is around x axis
roll is around y axis
