求两个旋转角度的中间值

sys.path.append(".")
print(os.path.dirname(os.path.abspath(__file__)))#当前文件的上级目录
from scipy.spatial.transform import Rotation as R
newrotateInfo1 = [1.0, 1.5, -3.0]
newrotateInfo2 = [-0.5, 2.0, -5.5]
r = R.from_euler(zyx, [[newrotateInfo1[0], newrotateInfo1[1], newrotateInfo1[2]],
[newrotateInfo2[0], newrotateInfo2[1], newrotateInfo2[2]]], degrees=True)
meanRotateValue = r.mean().as_euler(zyx, degrees=True)
print(meanRotateValue)
