摘要： Systems, techniques, and devices for detecting plant biometrics, for example, plants in a crop field. An imaging device of an unmanned vehicle may be used to generate a plurality of images of the plants, and the plurality of images may be used to generate a 3D model of the plants. The 3D model may define locations and orientations of leaves and stems of plants. The 3D model may be used to determine at least one biometric parameter of at least one plant in the crop. Such detection of plant biometrics may facilitate the automation of crop monitoring and treatment.

摘要： Pixel color values representing an image of a portion of a field are received where each pixel color value has a respective position within the image. A processor identifies groups of the received pixel color values as possibly representing a Nitrogen-deficient plant leaf. For each group of pixel color values, the processor converts the pixel color values into feature values that describe a shape and the processor uses the feature values describing the shape to determine whether the group of pixel color values represents a Nitrogen-deficient leaf of a plant. The processor stores in memory an indication that the portion of the field is deficient in Nitrogen based on the groups of pixel color values determined to represent a respective Nitrogen-deficient leaf.

摘要： Systems and methods for determining park stall occupancy are disclosed herein. The systems and methods include receiving a three dimensional representation of a parking stall in a parking lot. The systems and methods also include processing the three dimensional representation to determine occupancy of the parking stall. The parking stall has a boundary relative to the area.

摘要： A system includes an imager, a processor, and an output module. The imager is configured to provide a plurality of tissue images. The processor is coupled to the imager and is configured to receive the plurality of images. The processor is coupled to a memory. The memory has instructions for determining classification of a region of tissue associated with the plurality of tissue images. Determining classification includes fusing discriminator outputs from a region covariance descriptor and from a normalized color histogram discriminator. The output module is coupled to the processor. The output module is configured to provide a three dimensional representation of the tissue.

摘要： An unmanned aerial vehicle (UAV) including wing sections and hinge assemblies. Each wing section includes an airfoil and a propulsion unit. The wing sections are arranged side-by-side, pivotably connected by the hinge assemblies to define an airframe module. The airframe module is transitionable between a fixed-wing state and a rotor state. In the fixed-wing state, the airframe module has an elongated shape extending between opposing, first and second ends. In the rotor state, the first end is immediately proximate the second end. With this construction, the UAV provides two distinct modes of flight (fixed-wing for low power flight, and rotor for high maneuverability flight (including hover)). The wing sections can carry solar cells and a battery. A maximum power point tracker (MPPT) can be provided for optimizing the match between the solar array and the battery. The propulsion unit can include a variable pitch propeller.
