Title:
MODEL CREATION DEVICE, PROPAGATION CHARACTERISTIC IDENTIFICATION DEVICE, MODEL CREATION METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2023060988
Kind Code:
A
Abstract:
To estimate the radio propagation characteristics of radio waves by machine learning by using spatial image data.SOLUTION: A model creation device includes an image data acquisition unit 131 that acquires visible region image data for learning, a learning object detection unit 132 that detects the type of object and the position of the object, a characteristic data acquisition unit 133 that acquires radio wave propagation characteristic data for learning indicating radio wave propagation characteristics when radio waves are transmitted, and a model creation unit 134 that machine-learns visible region image data for learning, object detection information for learning, transmission position, reception position, and radio wave propagation characteristic data for learning as teacher data, and creates a radio wave propagation characteristic model for outputting radio wave propagation characteristic data indicating radio wave propagation characteristics when visible region image data, object detection information including information indicating the type of object and the position of the object, an input transmission position, and an input reception position are input.SELECTED DRAWING: Figure 2
