Abstract: A method is provided for horizon detection. The method includes acquiring an image that depicts a view of an environment, and defining a line pattern of lines that divide the image into respective pairs of image segments. The line pattern is formed of lines that are parallel, or intersecting at a common point of intersection. The method incudes searching the lines of the line pattern to identify one of the lines as an estimated true horizon in the image that divides the image into a respective pair of image segments at a boundary of greatest difference in average brightness between the image segments from among the respective pairs of image segments. The method includes determining true horizon in the image from the estimated true horizon. The method may also include an evaluation of the estimated true horizon or the true horizon as to verify one or more expected characteristics.

Abstract: A method of supporting robot(s) landing within a ground region is provided. The method includes accessing a map in which the ground region is tessellated into cells covering respective areas of the ground region. Each cell is classified as feasible to indicate a respective area is feasible for landing, or infeasible to indicate the respective area is infeasible for landing. The map is searched for clusters of adjoining cells that are classified as feasible, covering clusters of adjoining areas that define sub-regions within the ground region that are feasible for landing. The sub-regions are ranked according to a cost metric, and one of the sub-regions is selected according to the ranking. A geographic position of the selected sub-region is then output for use in at least one of guidance, navigation or control of the robot(s) to land at the selected sub-region within the ground region.

Abstract: A method includes receiving a first image that is captured at a first time. The method also includes detecting a location of a first object in the first image. The method also includes determining a region of interest based at least partially upon the location of the first object in the first image. The method also includes receiving a second image that is captured at a second time. The method also includes identifying the region of interest in the second image. The method also includes detecting a location of a second object in a portion of the second image that is outside of the region of interest.

Abstract: Methods and apparatus are disclosed for deployable wing portions of an aircraft. An example method of deploying an aircraft includes separating the aircraft from a launch vehicle, the aircraft having a wing pivotably coupled to a fuselage, rotating, about an axis of rotation, the wing relative to the fuselage from a first rotational orientation to a second rotational orientation different from the first rotational orientation, wherein, in the first rotational orientation, the wing extends along a direction that substantially aligns with a longitudinal axis of the fuselage, and extending the wing in a lateral direction away from the fuselage in the second rotational orientation.

Abstract: A digital video computing system receives two or more frames depicting an environment from a camera system of a vehicle. For a salient image feature identified in the two or more frames, a global motion vector is calculated that is indicative of movement of the feature at least partially attributable to movement of the vehicle. A local motion vector is calculated that is indicative of movement of the feature independent from the movement of the vehicle. Based on the local motion vector, the salient image feature is determined to have an apparent motion relative to the environment that is independent from the movement of the vehicle. A candidate image patch is identified including the salient image feature. The candidate image patch is analyzed to output a likelihood that the candidate image patch depicts a second vehicle.

Abstract: A vehicle is provided that includes a basic structure; and coupled to the basic structure, a plurality of power sources, a propulsion system and power distribution circuitry. The propulsion system includes a plurality of electric motors configured to power a plurality of propulsors to generate propulsive forces that cause the vehicle to move. The power distribution circuitry is configured to deliver direct current electric power from the plurality of power sources to the plurality of electric motors. The power distribution circuitry electrically couples the plurality of power sources to the plurality of electric motors in an interleaved topology in which electric motors of the plurality of electric motors are alternately, electrically coupled to power sources of the plurality of power sources. Each of the electric motors in the interleaved topology is electrically coupled to a different one of the power sources than immediately adjacent ones of the electric motors.

Abstract: A method of operating a cabin monitoring system. The cabin monitoring system can determine that an object is associated with an individual. The cabin monitoring system can further determine that the individual is exiting an area that includes the object. The cabin monitoring system can further include transmitting an alert to an output device based on determining that the individual is exiting the area that includes the object. The alert can indicate that the object has been left in the area.
