MediaPipe
MediaPipe(手部/人体关键点)CommonGoogle's open-source on-device toolkit that extracts hand and body keypoints in real time from an ordinary camera feed.
MediaPipe is Google's open-source (Apache 2.0), cross-platform, on-device machine learning framework, and MediaPipe Tasks provides ready-made vision tasks within it. Two are most relevant to embodied AI: Hand Landmarker first detects the palm, then regresses 21 hand keypoints within the cropped region, outputting image coordinates, metric world coordinates in meters, and left/right handedness; Pose Landmarker, built on BlazePose, outputs 33 body keypoints. Both run in real time on a phone's CPU and support mobile, web, and Python. Because it needs nothing more than an ordinary RGB webcam, MediaPipe is commonly used for low-cost gesture-based teleoperation, retargeting human hand motion onto a dexterous hand, or labeling keypoints on human videos; its 3D accuracy is limited under occlusion and complex gestures, so 3D hand-reconstruction models like HaMeR are used instead when higher accuracy is needed. The older Solutions interface stopped being supported in March 2023.
ExampleAn example program from dex-retargeting uses MediaPipe to detect human hand keypoints in real time from a laptop webcam, then retargets them into joint angles for an Allegro dexterous hand, making the simulated robotic hand mimic the person's hand movements.
