through finger detection. If we still find f finger, we can use PCA to analyze the finger's principal component, that is, the finger's direction. This is two constraints (it should be a vector) when you find a finger amount, the actual spatial position of the fingertip is fixed. Here there are three constraints (known ). When we remove the point clouds of our fingers, we have only the palm left. At this time, we can use PCA to analyze the direction of the palm. Here are three constraints (not
