DIGITAL PHOTOGRAMMETRY METHOD, ELECTRONIC DEVICE, AND SYSTEM

摘要

A digital photogrammetry method, an electronic device, and a system, which relate to the technical field of electronics and can reduce the operation complexity during image acquisition, expand the applicable scenarios of digital photogrammetry, and increase the reliability of photogrammetry. The method comprises: at different photographing positions, capturing a first image and a second image in different photographing directions, both the first image and the second image comprising a target object and a first object whose actual size is known; building a digital three-dimensional space according to the first image and the second image; and determining a distance between two endpoints of the target object according to the digital three-dimensional space and a size scaling ratio of the digital three-dimensional space and a real three-dimensional space, wherein the scaling ratio is related to the position of the first object in the first image, the position of the first object in the second image, and an actual size of the first object.
