Claim 11:
12. The method for generating a video retrieval mapping relationship of claim 11, wherein before performing the feature extraction operation on each frame picture in the video stream by using the feature extraction model to obtain the key feature sequence corresponding to each frame picture, the method for generating a video retrieval mapping relationship further includes:
inputting first training input data in a first training data set to a first initial neural network model to obtain first forward output data, wherein the first training data set includes the first training input data and first training output data, and the first training input data includes training frame pictures, and the first training output data includes key feature sequences corresponding to the training frame pictures;
adjusting weights and biases in the first initial neural network model according to an error between the first forward output data and the first training output data corresponding to the first training input data until an error between the first forward output data and the first training output data is less than or equal to a first threshold so as to obtain a first adjusted neural network model; and
determining the first adjusted neural network model as the feature extraction model.
