RECOGNITION PROCESSING DEVICE, RECOGNITION PROCESSING METHOD, AND PROGRAM

Provided are a recognition processing device, a recognition processing method, and a program capable of efficiently narrowing down a three-dimensional region on which recognition processing using a three-dimensional convolutional neural network is to be executed. A first recognition process executing section executes a first recognition process on a captured image obtained by capturing an image of a real space and used to generate voxel data. A target two-dimensional region determining section determines a two-dimensional region occupying part of the captured image on the basis of a result of the first recognition process. A target three-dimensional region determining section determines a three-dimensional region in the real space on the basis of the two-dimensional region and a position of a camera when the camera obtains the captured image. A second recognition process executing section executes a second recognition process using a three-dimensional convolutional neural network on the voxel data associated with a position in the three-dimensional region.
