The present invention proposes a classification method based on depth feature bags, which extracts the depth features of a representative image of a two-dimensional orthogonal plane, then uses the feature bag model to recode the extracted depth features, and finally uses the kernel fusion method Combining the characteristics of three two-dimensional orthogonal planes, the classification function is obtained to classify the image. This classification method greatly reduces the amount of calculation in the training and testing process, saves data space, and shortens the time of the entire calculation process. The "codebook" is used to encode image features to achieve high-dimensional sparse representation, making features more discriminative. It is more stable and more compact, and can alleviate the overfitting problem caused by insufficient data volume. The three two-dimensional orthogonal planes are multiplied by different weight coefficients when calculating the kernel function, which can make better use of the different spatial information contained in the three different sections, and the constructed classification function is more discriminative.
