Title:
TIMING PREDICTION METHOD, TIMING PREDICTION DEVICE, TIMING PREDICTION SYSTEM, PROGRAM, AND CONSTRUCTION MACHINERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/241487
Kind Code:
A1
Abstract:
The present invention acquires movement data for a plurality of points on an observed object that performs a prescribed movement operation, performs a frequency analysis on the movement data to generate feature value data, segments the feature value data to extract a transition array for a basic operation, and, by analyzing the frequency of occurrence of the basic operation during the prescribed movement operation on the basis of the transition array and an operation model obtained by learning a transition array for a basic movement obtained by segmenting the movement of a training object that performs a movement operation, extracts a pattern for the basic operation and thereby predicts the end timing of the prescribed movement operation.
