Layout rationality evaluation method and system based on graph attention network

The invention provides a layout rationality evaluation method based on a graph attention network, and the method comprises the steps: carrying out the training on the basis of an initialized 3D-SPAN network, and forming a small-sample three-dimensional scene evaluation network based on a 3D-SPAN-F frame; performing three-dimensional scene graph construction on the obtained indoor layout graph based on a three-dimensional scene layout rationality evaluation algorithm through a trained small sample three-dimensional scene evaluation network to generate a three-dimensional scene graph, and performing three-dimensional scene graph evaluation on the three-dimensional scene graph to generate a dichotomy evaluation result and a subjective logic evaluation result; in the whole process, the value of the constructed 3D-SPAD data set is fully mined, the relation between human subjective evaluation and scene complexity, scene categories and object categories and the relation between scene overall evaluation and object ev
