Abstract
A three-dimensional gesture detection device and a three-dimensional gesture detection method are provided. The three-dimensional gesture detection device includes a node detection unit, a gesture recognition model and a gesture trajectory detection unit. The node detection unit obtains several nodes according to each of the hand frames of a continuous hand image. The gesture recognition model obtains confidence levels of several gesture categories. The gesture trajectory detection unit includes a weight analyzer, a gesture analyzer, a key point classifier and a trajectory analyzer. The weight analyzer obtains weights of the gesture categories through a user interface. The gesture analyzer performs a weighting calculation on the confidence levels of the gesture categories to analyze a gesture on each of the hand frames. The key point classifier classifies several key points from the nodes. The trajectory analyzer obtains an inertial trajectory of the gesture according to the key points.
