不使用摄像头，使用标注好关键点的图片时，相机参数怎么设置？

1

你好，我这边使用网上找的图片计算三个角度，发现角度与实际偏差较大，是不是与相机参数K和D有关，此时相机参数应该怎么设？

object_pts 是不变的吗?

您好, 目前我没改 video_test_shape.py中的object_pts, 只是将K 和D 换成了自己的相机内参, 得到的结果也很近似. 所以, object_pts 是不变的吗? 如果需要改变,要怎么获取呢? 谢谢

Where object_pts come from?

Where `object_pts` come from? https://github.com/lincolnhard/head-pose-estimation/blob/master/video_test_shape.py#L16

Where do the object_points come from and which in which units are they measured?

Hi @lincolnhard, first - thanks for the nice project. I would like to know where do the values for the object_points come from and in which units are they?

decomposeProjectionMatrix计算出的角度抖动的厉害

该函数计算的欧拉角在人脸静止时，数据抖动得厉害，查了下原因似乎是旋转矩阵转换为欧拉角结果不是唯一，暂时没找到解决办法，请问有什么解决方案吗

I am using 68_face_landmarks.dat modual in my project but its not enough stable and accurate. So the face mesh keeps vibrating. So is there any way to make it more...

How to get Yaw, Pitch, Roll?

Thank you for sharing your code. Is there any way to get Yaw, Pitch, and Roll of the head?

@lincolnhard thanks for your work. I am using the below code to find the head pose looing direction. (left, right, top, bottom) ``` y_value = float(str("{:7.2f}".format(euler_angle[1, 0]))) x_value = float(str("{:7.2f}".format(euler_angle[0,...

请问在Python版本与C++ 版本的帧率分别是多少？ 在同一台机器上实现之后，为什么明显C++版本要比Python版本慢了几倍？（Linux下Cmake编译）是需要有什么选项的设置吗？还是dlib本身的原因？
