1. A method, comprising: generating first keypoint signatures of an object from an image of the object; and identifying the object using the first keypoint signatures, wherein identifying the object comprises: comparing the first keypoint signatures to assembly reference keypoint signatures, the assembly reference keypoint signatures comprising keypoint signatures of multiple views of assemblies containing sets of components; and based on the comparison of the first keypoint signatures to the assembly reference keypoint signatures, comparing the first keypoint signatures to component reference keypoint signatures, the component reference keypoint signatures comprising keypoint signatures of the components.
