Title:
ELECTRONIC DEVICE PERFORMING CAMERA CALIBRATION, AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/053876
Kind Code:
A1
Abstract:
Provided are an electronic device performing calibration between a plurality of cameras, and an operation method therefor. An electronic device, according to one embodiment of the present disclosure, may perform camera calibration by: extracting first joint feature points, which are two-dimensional position coordinates of a user's joints, from a first image acquired by a first camera; extracting second joint feature points, which are two-dimensional position coordinates of the user's joints, from a second image acquired by a second camera; obtaining three-dimensional joint feature points of the joints by lifting the extracted first joint feature points into three-dimensional position coordinates; obtaining a projection relationship for projecting the three-dimensional joint feature points to two-dimensional position coordinate values of the second joint feature points; and predicting the positional relationship between the first camera and the second camera on the basis of the projection relationship.
