show angle result?

[roachsinai]

//show angle result
outtext << "X: " << std::setprecision(3) << euler_angle.at<double>(0);
cv::putText(temp, outtext.str(), cv::Point(50, 40), cv::FONT_HERSHEY_SIMPLEX, 0.75, cv::Scalar(0, 0, 0));
outtext.str("");
outtext << "Y: " << std::setprecision(3) << euler_angle.at<double>(1);
cv::putText(temp, outtext.str(), cv::Point(50, 60), cv::FONT_HERSHEY_SIMPLEX, 0.75, cv::Scalar(0, 0, 0));
outtext.str("");
outtext << "Z: " << std::setprecision(3) << euler_angle.at<double>(2);
cv::putText(temp, outtext.str(), cv::Point(50, 80), cv::FONT_HERSHEY_SIMPLEX, 0.75, cv::Scalar(0, 0, 0));
outtext.str("");

Seems it should be: Y-Z-X means, pitch-yaw-roll?

@lincolnhard and @roachsinai, please help.
How to calculate pitch angle with Python?

What do you mean?

head-pose-estimation/video_test_shape.py

Line 60 in 4f3d5d7

_, _, _, _, _, _, euler_angle = cv2.decomposeProjectionMatrix(pose_mat)

@roachsinai , I figured it out already 👍 yeah that is also right.
I think what you were asking are actually euler angles, that are displayed on the video capture, they are X for pitch,... respectively.
