Systems and methods for scale invariant 3D object detection leveraging processor architecture

摘要

An example method includes receiving a plurality of templates of a plurality of objects, where a template comprises feature values sampled at corresponding points of a two-dimensional grid of points positioned over a particular view of an object and scaled based on a depth of the object at the particular view. The method may further include receiving an image of an environment and determining a matrix representative of the image, where a row of the matrix comprises feature values sampled at a particular point of the two-dimensional grid positioned over one or more locations within the image and scaled based on depths of the one or more locations. The method may additionally include determining at least one similarity vector corresponding to at least one template and using the at least one similarity vector to identify at least one matching template for at least one object located within the image.
