Classification: CPC G | IPC G

Claim 0:
1. A computer-implemented action imitation method for a robot, comprising steps of:
collecting at least a two-dimensional image of a to-be-imitated object;
obtaining two-dimensional coordinates of each key point of the to-be-imitated object in the two-dimensional image and a pairing relationship between key points of the to-be-imitated object, wherein the pairing relationship between the key points of the to-be-imitated object is for representing a relative positional relationship between adjacent joints; and
converting the two-dimensional coordinates of each key point of the to-be-imitated object in the two-dimensional image into space three-dimensional coordinates corresponding to the key points of the to-be-imitated object through a pre-trained first neural network model, and generating an action control instruction of the robot based on the space three-dimensional coordinates corresponding to the key points of the to-be-imitated object and the pairing relationship between the key points, wherein the action control instruction is for controlling the robot to imitate an action of the to-be-imitated object;
wherein the step of obtaining the two-dimensional coordinates of each key point of the to-be-imitated object in the two-dimensional image and the pairing relationship between the key points of the to-be-imitated object comprises:
inputting the two-dimensional image into a pre-trained second neural network model, and obtaining the two-dimensional coordinates of each key point of the to-be-imitated object in the two-dimensional image and the pairing relationship between the key points of the to-be-imitated object outputted by the pre-trained second neural network model.
