Euler angles (roll angle, pitch angle, yaw angle), rotation matrix, quaternion conversion and solution to universal joint deadlock

1. Overview The description method of the pose (position and direction) of an object is generally represented by two coordinate systems. One is the world coordinate system or the ground coordinate system. Here I call it the ground coordinate system, which belongs to the reference coordinate system; the other is its own Coordinate system, it […]

TOOLS_Python to get the range of pitch

Based on the librosa.pyin method (link) to obtain the maximum value of the fundamental frequency, compare the standard pitch sequence to obtain the range of the pitch; def create_standard_pitch_sequence(): “”” generate a canonical pitch sequence with names “”” T = [“C”,”C?/D?”, “D”, “D?/E?”,”E”,”F”,”F ?/G?”,”G”,”G?/A?”,”A”,”A?/B?”,”B”] t0 = [0,1,2,3,4,5,6,7,8,9] c = [[16.352, 32.703, 65.406, 130.81, 261.63, 523.25, […]
