The invention discloses a multispectral neural network fused sheet metal part deformation stress distribution prediction method, and belongs to the technical field of sheet metal part stress detection. In order to solve the problem that non-contact full-field prediction is difficult to realize by simultaneously utilizing a deformation field and a temperature field in existing sheet metal part stress distribution prediction, the method comprises the following steps: acquiring visible light, a first infrared multispectral image sequence and a second infrared multispectral image sequence when a sheet metal part bears an external load, and calculating deformation field data according to displacement of a mark point in a visible light image; calculating temperature field data according to a radiation brightness difference value of the two infrared band images, stacking a normalized deformation field and a normalized temperature field in a channel dimension to form a multi-channel feature tensor, inputting the multi-channel feature tensor into a three-dimensional convolutional neural network comprising at least three convolutional layers and two pooling layers, outputting a stress distribution probability graph corresponding to each stress value interval, and obtaining a stress distribution probability graph corresponding to each stress value interval; and taking a maximum probability corresponding interval to generate a final stress distribution prediction map. The method is mainly used for the non-contact prediction of the surface stress distribution of the sheet metal part under the static or dynamic load.
