Title:
SLEWING ANGLE MEASUREMENT DEVICE AND METHOD FOR WORK MACHINE, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/004733
Kind Code:
A1
Abstract:
The present invention acquires a plurality of images of the external world as viewed from a slewing structure of a work machine that are arranged in time series and are generated by an imaging unit that is provided so as to move along with the slewing of the slewing structure. For each image from among the plurality of images, the image and an image that immediately precedes the image in the time series are referred to to determine a first slewing angle of the slewing structure with reference to the position of the slewing structure relative to a base body in the first image among the plurality of images. On the basis of the plurality of first slewing angles determined for the plurality of images, a predetermined point in the external world is determined as a reference for the slewing angle. For each image from among the plurality of images, the first slewing angle determined for the image and the reference are referred to to determine a second slewing angle of the slewing structure relative to the reference.
