US Patent 11176416 Perception device

A perception device includes: a first neural network that performs a common process associated with perception of an object and thus outputs results of the common process; a second neural network that receives an output of the first neural network and outputs results of a first perception process of perceiving the characteristics of the object with a first accuracy; and a third neural network that receives the output of the first neural network and intermediate data which is generated by the second neural network in the course of the first perception process and outputs results of a second perception process of perceiving the characteristics of the object with a second accuracy which is higher than the first accuracy.
