Abstract: Example aspects of the present disclosure relate to an example computer-implemented method for data annotation for training machine perception models. The example method can include (a) receiving source sensor data descriptive of an object, the source sensor data having a source reference frame of at least three dimensions, wherein the source sensor data includes annotated data associated with the object; (b) receiving target sensor data descriptive of the object, the target sensor data having a target reference frame of at least two dimensions; (c) providing an input to a machine-learned boundary recognition model, wherein the input includes the target sensor data and a projection of the source sensor data into the target reference frame; and (d) determining, using the machine-learned boundary recognition model, a bounded portion of the target sensor data, wherein the bounded portion indicates a subset of the target sensor data descriptive of the object.
