Three-dimensional human body model reconstruction method, storage equipment and control equipment

The invention relates to the technical field of human body model reconstruction, in particular to a three-dimensional human body model reconstruction method, storage equipment and control equipment, and aims to solve the problems that a three-dimensional model reconstruction result is not aligned with a two-dimensional image and the like. The reconstruction method comprises the steps that according to a human body image, adopting a pre-trained full convolutional network module to acquire a global UVI image and a local UVI image of a human body part; estimating camera parameters and shape parameters of the human body model by using a first neural network based on the global UVI graph; based on the local UVI graph, utilizing a second neural network to extract rotation features of each articulation point of the human body; based on the rotation characteristics of each articulation point of the human body, improving the rotation characteristics by utilizing a characteristic improvement strategy based on position assistance to obtain improved rotation characteristics; and estimating attitude parameters of the human body model by using a third neural network according to the improved rotation characteristics. According to the method, the human body model can be reconstructed more accurately and efficiently, and the robustness of attitude estimation is improved.

Building indoor learning efficiency detection method and system

The invention relates to a building indoor learning efficiency detection method and system. The method comprises the following steps: S1, acquiring electroencephalogram signal data; S2, preprocessingthe acquired electroencephalogram signal data; S3, extracting energy features of the preprocessed electroencephalogram signals under different electrode channels through features; and S4, taking the energy features under corresponding electrode channels of the feature extraction as input features, and inputting the input features into a BP neural network to realize classification of learning attention. Energy features of the electroencephalogram signals under different electrode channels are extracted through features, and are taken as input features of a subsequent classifier, and the attention state of a learner is accurately reflected; accurate classification of electroencephalogram signals is realized; and accurate, stable and reliable measurement of the concentration degree of the attention electroencephalogram signals is realized, and wide influence is generated on attention action mechanisms in human brains in psychology and neurophysiology.
