Detection-Guided 3D Hand Tracking for Mobile AR Applications
Interaction using bare hands is experiencing a growing interest in mobile-based Augmented Reality (AR). Existing RGB-based works fail to provide a practical solution to identifying rich details of the hand. In this paper, we present a detection-guided method capable of recovery 3D hand posture with a color camera. The proposed method consists of key-point detectors and 3D pose optimizer. The detectors first locate the 2D hand bounding box and then apply a lightweight network on the hand region to provide a pixel-wise like-hood of hand joints. The optimizer lifts the 3D pose from the estimated 2D joints in a model-fitting manner. To ensure the result plausibly, we encode the hand shape into the objective function. The estimated 3D posture allows flexible hand-to-mobile interaction in AR applications. We extensively evaluate the proposed approach on several challenging public datasets. The experimental results indicate the efficiency and effectiveness of the proposed method.
