Abstract
A finger interaction trajectory acquisition method and system, and a storage medium are provided. The method includes: acquiring, in response to an individual hand interacting with a target object through a finger, motion posture information continuously collected by a three-dimensional motion capture system to obtain three-dimensional position coordinates of a to-be-measured joint or bone of the individual hand; sequentially determining whether a finger position at each timestamp is located on the target object in a predetermined coordinate system, and storing, in response to determining that a finger interaction occurs, the position coordinates of the distal phalanx as an interaction position point and storing the corresponding timestamp; and drawing a finger trajectory and a finger interaction trajectory.
