Abstract: Methods and systems for determining depth information using a combination of stereo and structured-light processing are provided. An example method involves receiving a plurality of images captured with at least two optical sensors, and determining a first depth estimate for at least one surface based on corresponding features between a first image and a second image. Further, the method involves causing a texture projector to project a known texture pattern, and determining, based on the first depth estimate, at least one region of at least one image of the plurality of images within which to search for a particular portion of the known texture pattern. And the method involves determining points corresponding to the particular portion of the known texture pattern within the at least one region, and determining a second depth estimate for the at least one surface based on the determined points corresponding to the known texture pattern.

Abstract: Example systems and methods may be used to determine a trajectory for moving an object using a robotic device. One example method includes determining a plurality of possible trajectories for moving an object with an end effector of a robotic manipulator based on a plurality of possible object measurements. The method may further include causing the robotic manipulator to pick up the object with the end effector. Alter causing the robotic manipulator to pick up the object with the end effector, the method may also include receiving sensor data from one or more sensors indicative of one or more measurements of the object. Based on the received sensor data, the method may additionally include selecting a trajectory for moving the object from the plurality of possible trajectories. The method may further include causing the robotic manipulator to move the object through the selected trajectory.
