Abstract
Techniques are disclosed for using tag placement to determine 3D object orientation. An extended reality (XR) system detects, in a two-dimensional image, a data marker associated with an object viewable in an XR environment. The XR system applies a first function to the data marker to generate a rectilinear data marker by transforming a quadrilateral that circumscribes the data marker into a rectangle. The XR system determines a three-dimensional orientation of the object based on transformation of the data marker to the rectilinear data marker. The XR system determines an XR object associated with the data marker. The XR system applies a second function to the XR object, where the second function uses the three-dimensional orientation of the data marker to modify an orientation of the XR object to generate a transformed XR object. The XR system causes the transformed XR object to be displayed within the two-dimensional image.
