Perform Human Pose Estimation in OpenCV Using OpenPose MobileNet

OpenCV Using OpenPose MobileNet

How to use

  • Test with webcam
python openpose.py
  • Test with image
python openpose.py --input image.jpg
  • Use --thr to increase confidence threshold
python openpose.py --input image.jpg --thr 0.5

Notes:

  • I modified the OpenCV DNN Example to use the Tensorflow MobileNet Model, which is provided by ildoonet/tf-pose-estimation, instead of Caffe Model from CMU OpenPose. The original openpose.py from OpenCV example only uses Caffe Model which is more than 200MB while the Mobilenet is only 7MB.
  • Basically, we need to change the cv.dnn.blobFromImage and use out = out[:, :19, :, :] to get only the first 19 rows in the out variable.
