TRIANGULATION-BASED COORDINATE POSITIONING METHOD, APPARATUS, AND DEVICE AND STORAGE MEDIUM

摘要

Provided are a triangulation-based coordinate positioning method, apparatus, and device and a storage medium for use in the technical field of computers. The method comprises: acquiring image coordinates of a target marker point projected onto the imaging plane of multiple photographic units and, on the basis of the multiple image coordinates, acquiring initial three-dimensional coordinates of the target marker point (S201); on the basis of the initial three-dimensional coordinates and the multiple image coordinates, determining an angular positioning error of the target marker point (S202); and, on the basis of the initial three-dimensional coordinates and the angular positioning error, acquiring optimised three-dimensional coordinates of the target marker point (S203). The present triangulation-based coordinate positioning method corrects the initial three-dimensional coordinates on the basis of the angular positioning error of the target marker point, and compared to methods in the prior art for performing correction on the basis of the distance error of three-dimensional coordinates, is not affected by the distance between the photographic units and the target marker point, increasing the precision of coordinate positioning.
