In other words, is the head pose matrix composed of the translation matrix?

代码中相机内参用的是0 # self.dist_coeefs = np.zeros((4, 1)) 我用标定后的畸变参数是不是会更精准一些
另外,# self.r_vec = np.array([[0.01891013], [0.08560084], [-3.14392813]])
# self.t_vec = np.array(
# [[-14.97821226], [-10.62040383], [-2053.03596872]])
这两个数据的值 是怎么来的, 输出的结果不应该才是这两个吗

① 有标定参数的话优先使用标定参数。
② 该数值是我算出来的经验值,在此基础上迭代不容易出错。

输出的tvec 经验证是tx ty tz,但是rvec不是对应坐标轴的旋转向量 且rvec[ [0.129] [0.039] [-3.26]] 对应的第三索引的值在-3左右波动 这是对应pitch yaw roll的哪个偏转角?

时间久远,我记得不太清楚了。旋转矩阵不直接对应pitch yaw roll角度,需要使用之前提到的方法转换为角度。
