Abstract
In one embodiment, a method includes instructing, at a first time, a camera having a plurality of pixel sensors to capture a first image of an environment comprising an object to determine a first object pose; determining, based on the first object pose, a predicted object pose of the object at a second time; generating pixel-activation instructions based on a buffer region around a projection of a 3D model of the object having the predicted object pose onto a virtual image plane associated with a predicted camera pose, where the size of the buffer region may be dependent on predicted dynamics for the object; instructing, at the second time, the camera to use a subset of the plurality of pixel sensors to capture a second image of the environment according to the pixel-activation instructions, and; determining, based on the second image, a second object pose of the object.
