Abstract: An approach is provided for structure-aided visual localization (SAVLoc). The approach involves, for example, processing an image captured by a camera device to determine one or more pixel coordinates of one or more structural components depicted in the image. The approach also involves determining an approximate pose of the camera device at a time the image was captured and a correspondence of the one or more structural components to one or more known components based on the approximate. The approach further involves querying a database for one or more location coordinates of the one or more known components based on the correspondence. The approach further involves computing a pose estimation of the camera device based on one or more location coordinates and the one or more pixel coordinates.

Abstract: Systems and methods for identifying features(s) of crops are provided. One example computer-implemented method includes accessing image data specific to a cotton plant. The image data includes images of the cotton plant and, for each image, depth data indicative of a range between surfaces of the cotton plant and a camera(s) that captured the image. The image data further includes tracking data for a device including the camera(s). The method also includes stitching together point clouds, which are defined by the images of the cotton plant, and identifying brighter white segments and darker white segments in the stitched point clouds. The brighter white segments and darker white segments define segment pairs. The method then also includes appending a line between the brighter white segment and the darker white segment of each of the pairs and determining a feature of the cotton plant based on the appended lines and/or pairs.

Abstract: Systems and methods for processing image data for crops are provided. One example computer-implemented method includes accessing image data specific to a corn plant, where the image data includes an image of the corn plant and depth data indicative of a range between the corn plant and a camera, which captures said image, and identifying, by a computing device, using a trained model, a feature of the corn plant, the feature including an ear of the corn plant and/or a node from which the ear emerges. The method also includes transforming, by the computing device, coordinates specific to the feature into a height of the feature of the corn plant and storing, by the computing device, the height of the feature of the corn plant in a memory.

Abstract: Methods for verifying and updating connectivity information in a geographic information system may consider location information for meters and transformers and voltage data obtained by the meters. Meters that are incorrectly associated with a transformer may be flagged and candidate transformers may be evaluated to identify a correct association. The analysis may consider voltage data from multiple meters to determine correlation values. Correlation values or confidence factors may be used to identify a transformer for the correct association.

Abstract: A method is provided to predict a disaster for a computer system based on logs. The method includes representing existing logs as first vectors by tokenizing the existing logs and partitioning the first vectors into clusters. The clusters represent disaster types. The method further includes selecting representative vectors for the clusters, representing a new log of the computer system as a second vector by tokenizing the new log, matching the second vector to a cluster by comparing the second vector and the representative vectors, and categorizing the new log as a disaster type represented by the cluster.

Abstract: An inflatable slide-raft may include a primary inflatable structure configured to inflate upon deployment of the inflatable slide-raft, a first secondary inflatable structure coupled to the primary inflatable structure, and a second secondary inflatable structure coupled to the primary inflatable structure. The first secondary inflatable structure and the second secondary inflatable structure siderail are configured to remain in a stowed state when the inflatable slide-raft is operated in a slide mode and to inflate when the inflatable slide-raft is operated in a raft mode.

Abstract: Present disclosure relates to an assembly for mounting solar panel tiles or other tiles/panels over a roof (surface). Assembly includes C-shaped base frames provided with holes at the bottom for fixing them parallelly over the roof. Rows of tiles are then mounted over two adjacent base frames. Assembly further includes Z-shaped clamping frames for holding the tile which sits and is mounted on the base frames. Clamping frames hold the tile at the top, and the bottom of another tile resting on a previous clamping frame. An area close to the bottom edge of tiles has a layer of adhesive that helps in attaching the bottom edge of tile to the top of a previous clamping frame, thereby making the assembly aesthetically pleasing and leakproof. Another set of holes are provided on the base frames, and clamping frames, to allow cables to pass through them, and provide proper ventilation beneath the assembly.

Abstract: A system and method for expedited tile installation are disclosed. The system may include a clamp strip and at least one tile. The clamp strip may be made of conjoined foldable strips. Each strip may include one or more clamps. The clamp strip role may be configured to unroll on a surface. The clamp strip may be adhered to the surface, after unrolling, using one or more fastening mechanisms. The at least one tile may include one or more wedges fixed to a rear side of the at least one tile. Each wedge may be configured to be inserted into the one or more clamp for installing the at least one tile. The one or more clamps and the one or more wedges may be configured to interlock for gripping the at least one tile to the clamp strip.
