Abstract
A computer-implemented method of creating one or more annotated perception inputs, the method comprising, in an annotation computer system: receiving a plurality of captured frames, each frame comprising a set of 3D structure points, in which at least a portion of a common structure component is captured; computing a reference position within at least one reference frame of the plurality of frames; generating a 3D model for the common structure component by selectively extracting 3D structure points of the at least one reference frame based on the reference position within that frame; determining an aligned model position for the 3D model within a target frame of the plurality of frames based on one or more manual alignment inputs received in respect of the target frame at a user interface whilst rendering the 3D model for manually aligning the 3D model with the common structure component in the target frame; and storing annotation data of the aligned model position in computer storage, in association with at least one perception input of the target frame for annotating the common structure component therein.
