OpenCV project development practice--step by step introduction to human body pose estimation based on deep learning using OpenPose--C++/Python source code

At the end of the article, the test code download link based on Python and C++ is attached.

In this tutorial, use OpenCV for deep learning based human pose estimation. We'll detail how to use pretrained Caffe models in your own applications. 

1. Pose estimation (aka key point detection)

Pose estimation is a general problem in computer vision where we detect the position and orientation of objects. This usually means detecting keypoint locations describing objects.

For example, in the problem of facial pose estimation (aka facial landmark detection), we detect landmarks on human faces.
