PoseCamera

PoseCamera is python based SDK for human pose estimation through RGB webcam.

Install

install posecamera package through pip

pip install posecamera

If you are having issues with the installation on Windows OS then check this page

Usage

See Google colab notebook https://colab.research.google.com/drive/1pzsgxaz1ZVesh_j-96PBak_OQKP19HHA?usp=sharing

draw pose keypoints on image

import posecamera
import cv2

det = posecamera.pose_tracker.PoseTracker()

image = cv2.imread("example.jpg")

pose = det(image)
for name, (y, x, score) in pose.keypoints.items():
    cv2.circle(image, (int(x), int(y)), 4, (255, 0, 0), -1)


cv2.imshow("PoseCamera", image)
cv2.waitKey(0)

output of the above example

or get keypoints array

for pose in poses:
    keypoints = pose.keypoints

Handtracker

import posecamera
import cv2
det = posecamera.hand_tracker.HandTracker()

image = cv2.imread("tmp/hands.jpg")
keypoints, bbox = det(image)

for hand_keypoints in keypoints:
    for (x, y) in hand_keypoints:
        cv2.circle(image, (int(x), int(y)), 3, (255, 0, 0), -1)

cv2.imshow("PoseCamera - Hand Tracking", image)
cv2.waitKey(0)

Using Docker

The official docker image is hosted on Docker Hub. The very first step is to install the docker docker on your system.

Also note that your Nvidia driver Needs to be compatible with CUDA10.2.

Doing inference on live webcam feed.

xhost +; docker run --name posecamera --rm --net=host --gpus all -e DISPLAY=$DISPLAY --device=/dev/video0:/dev/video0 wondertree/posecamera --video=0

GPU & Webcam support (if running docker) is not available on Windows Operating System.

To run inference on images use the following command.

docker run --name posecamera --rm --net=host -e DISPLAY=$DISPLAY  wondertree/posecamera --images ./tmp/female_pose.jpg --cpu
