The invention discloses a scene multi-object three-dimensional reconstruction representation method based on three feature planes. The method comprises the following steps: firstly, extracting and associating image masks of objects and backgrounds of an RGB
data set; designing a feature three-plane
network model, and initializing an object parallel
network model and a background
network model; sampling points are extracted according to the
mask region for intra-region supervision; obtaining a network model output result according to the sampling point information; designing a
loss function for the network model according to an output result of the network model, and training an object parallel network model and a background network model; and finally, performing combined scene grid extraction by using the trained network model. According to the multi-object reconstruction strategy based on the implicit truncation symbol distance field, the convergence speed is obviously higher than that of common rendering representation based on
volume density and occupancy, and the reconstruction effect with higher quality can be achieved.
