Title:
THREE-DIMENSIONAL IMAGE MEASUREMENT METHOD, ELECTRONIC DEVICE, STORAGE MEDIUM, AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/173052
Kind Code:
A1
Abstract:
Disclosed are a three-dimensional image measurement method, an electronic device, a storage medium, and a program product. The three-dimensional image measurement method comprises the steps of: performing feature extraction on a medical image scanned by a scanning device; performing image matching on the medical image subjected to feature extraction; calibrating the scanning device to determine intrinsic parameters of the scanning device; performing three-dimensional reconstruction on the medical image according to the intrinsic parameters of the scanning device to obtain a three-dimensional image; and projecting the three-dimensional image to a two-dimensional image, and calculating the size of a target region according a mapping relationship between three-dimensional spatial points and two-dimensional image points. The present invention implements real-time measurement of a three-dimensional image by extracting feature information of the image, performing image matching, performing calibration, performing reconstruction, performing measurement, etc., has the characteristics of high precision, good stability, non-contact measurement, etc., and is a practical measurement method having high degree of automation.
