Claim 15:
16. The robot of claim 15, wherein the instructions for training the to-be-trained first neural network model based on the third sample two-dimensional coordinates and the predetermined first sample three-dimensional coordinates comprises:
instructions for inputting the third sample two-dimensional coordinates into the to-be-trained first neural network model, to train the to-be-trained first neural network model;
instructions for obtaining second sample three-dimensional coordinates corresponding to the third sample two-dimensional coordinates outputted by the to-be-trained first neural network model;
instructions for calculating a second loss function value of the second sample three-dimensional coordinates and the first sample three-dimensional coordinates;
instructions for determining whether the second loss function value is less than a third threshold and a change rate of the second loss function value is less than a fourth threshold; and
instructions for, in response to the second loss function value not being less than the third threshold or the change rate of the second loss function value not being less than the fourth threshold, returning to perform the step of inputting the third sample two-dimensional coordinates into the to-be-trained first neural network model, until when the second loss function value is less than the third threshold and the change rate of the second loss function value is less than the fourth threshold, stopping the training, and obtaining the pre-trained first neural network model.
