Wheat new view angle synthesis method based on improved neural radiation field population

The invention discloses a new visual angle synthesis method for group wheat based on an improved neural radiation field, and relates to the technical field of computer vision, and the method comprises the following steps: shooting an image of group wheat, and constructing a group wheat data set; constructing a neural radiation field of the group wheat scene, generating rays in the neural radiation field, obtaining sampling points according to a neural radiation field sampling strategy, and obtaining 3D positions and directions of the sampling points; inputting the 3D position x of the sampling point into a multi-plane Hash encoder, inputting the encoded data into a neural radiation field network, carrying out rendering loss training, and predicting the color and density of the sampling; after training is completed, a new image of a new view angle can be obtained. The method has the advantages that a reference image guiding strategy is adopted, multi-plane Hash coding improvement is carried out on the NeRF net
