Title:
RELATIVE POSITION MEASURING DEVICE, RELATIVE POSITION MEASURING METHOD, AND RELATIVE POSITION MEASURING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/044777
Kind Code:
A1
Abstract:
[Problem] To achieve high-accuracy measurement of a three-dimensional position with respect to a designated target point by means of simple configuration. [Solution] This relative position measurement device 10 is provided with a sensor 102 and a calculation unit 50. The sensor 102 is equipped with: a monocular camera 20 for capturing an image; and a ranging unit 30 for measuring relative three-dimensional coordinates of a feature point in the image. The calculation unit 50 determines, from a ranging result of the feature point, relative three-dimensional coordinates of a target point designated within the image.
