Abstract: An illustrative multi-view 3D positioning system assigns a respective 3D position estimate, with respect to a 3D space, to each of a plurality of detected instance datasets corresponding to objects present within the 3D space. Based on the 3D position estimates, the multi-view 3D positioning system sorts the plurality of detected instance datasets into a plurality of groupings corresponding to the objects so that each detected instance dataset is grouped together with other detected instance datasets corresponding to a same object. The multi-view 3D positioning system then determines a respective 3D position resolution, with respect to the 3D space, for each of the plurality of objects. These 3D position resolutions are determined based on the plurality of groupings of detected instance datasets and represent, with greater accuracy than the 3D position estimates, 3D positions of the objects within the 3D space. Corresponding methods and systems are also disclosed.
