摘要： A computer-implemented method of performing a three-dimensional 3D point cloud registration with multiple two-dimensional (2D) images may include estimating a mathematical relationship between 3D roto-translations of dominant planes of objects in a 3D point cloud and bi-dimensional homographies in a 2D image plane, thereby resulting in a 3D point cloud registration using multiple 2D images. A trained classifier may be used to determine correspondence between homography matrices and inferred motion of the dominant plane(s) on a 3D point cloud for paired image frames. A homography matrix between the paired images of the dominant plane(s) on the 2D image plane may be selected based on the correspondence between the inferred motions and measured motion of the dominant plane(s) on the 3D point cloud for the paired image frames. The process may be less computationally intensive than conventional 2D-3D registration approaches.

摘要： Systems and methods for applying and detecting cross dependent marks incorporated into an electronic or digital image to form a watermark. The electronic or digital image may include encoded information for example a machine-readable symbol. The watermarking may include an encoding and insertion sub-process that inserts one or more marks into an image at a first point in time for form a marked image, an extraction sub-process that extracts the marks at a second point in time, and a detection sub-process 108 that determines if any modifications have been made to the marked image. The marked image may be formed by determining a first original descriptor and first original mark within the image, determining a second original descriptor and second original mark within the image, and incorporating the first original mark into the second original descriptor and incorporating the second original mark into the first original descriptor.

摘要： A hand-held barcode reader has a decoding module that analyzes barcodes on a surface. The decoding module determines a displacement based on a current position of the hand-held barcode reader and a desired new position of the hand-held barcode reader with respect to a barcode on the surface. An LED of the hand-held barcode reader produces a first-colored light-spot at a position on the surface to direct a desired movement of the hand-held barcode reader to move from the current position to the desired new position.

摘要： A system and method of executing a deep neural network (DNN) in a local area network (LAN) may include executing a partitioned deep neural network in multiple computational nodes (CPs) in devices operating on the LAN. An image frame may be captured by a device. The image frame may be processed by a first layer of the partitioned neural network by a CP operating on the device. In response to the device that captured the image frame determining to request processing assistance from another CP, a request using a peer-to-peer protocol to other CPs on the LAN may be performed. A feature map may be communicated to another CP selected using the peer-to-peer protocol to process the feature map by a next layer of the DNN.

摘要： Systems, methods, and computer-readable storage media are provided for identifying (recognizing) an object from its shape in a sequence of images utilizing sequence alignment matrices (SAMs). For a given image, an object is segmented and from the segmented object, a set of key points is extracted. From the extracted key points, a set of local feature descriptors, strictly related to the key points and uniquely ordered in sequence, are extracted. The feature sequence obtained from the segmented object is aligned with a counterpart or reference image (e.g., a model or another image) using a Sequence Alignment Matrix (SAM). A custom scoring technique for the alignment provides a quality index for the identification of the object.

摘要： Various embodiments of the invention are implemented with a mobile camera and safety laser scanner. A mobile computer can be used to show a visible infrared beam on the display of the mobile computer. The mobile computer can function as a safety tool to identify regions or locations where a laser beam might penetrate. The mobile computer can determine if the laser beam has penetrated a safety region or zone. Sensors can be used to determine when a laser beam may become dangerously close to an operator, especially with the use of automated guided vehicle that is moving around and has a scanning laser.

摘要： The disclosure includes imaging systems employing event-based sensors in various applications for analyzing a scene, such as those involved in conveyor systems, mass flow detection systems, portals, machine vision systems, retail settings including checkout stations, and the like. Event-based sensors may be operated in conjunction with frame-based cameras to select frames or subparts of frames or otherwise trigger actions related to the imaging system based on analysis of the events generated by the event-based sensors.

摘要： Systems and methods for autofocus may include a light source for generating a light wave and a varifocal lens arranged in front of the light source. The varifocal lens may receive the light wave and generate a Fourier transform of a known semi-transparent pattern positioned on the rear focal plane (or input plane) of the varifocal lens therefrom. An image sensor may receive the Fourier transform carried by the light wave after being reflected from an object. A focus tunable lens may be arranged in front of the image sensor and through which the reflected light wave passes. A processor may adjust a focal length of the varifocal lens to cause the Fourier transform carried by the light wave to form a predefined (expected) pattern detected by the image sensor, and adjust a control parameter of the focus tunable lens until one or more spatial frequencies of the predefined pattern detected at the image sensor match one or more predefined spatial frequencies.

摘要： A system and method of processing and analyzing data captured by automatic data collection (“ADC”) readers. The ADC readers encapsulate the captured data in markup language pages and associate various metadata with these pages. A markup language document analyzer identifies associations or links between the meta-data stored in multiple markup language pages. Once an association is detected, the analyzer stores a corresponding hyperlink in one or both of the associated HTML pages 102. After the hyperlinks are stored, a rankings engine may rank the markup language pages based on the hyperlinks that have been stored. The rankings engine may continue to rank the pages as new links are identified and as new pages are created and stored. Queries related to the data received from the ADC readers 100 may be received and processed based upon the rankings of the processed markup language pages.

摘要： Systems and methods for providing reliability and redundancy of data for networked nodes (e.g., sensors and/or actuators) is provided. Each sensor may operate as network node in the sensor network that may operate as a peer to peer (P2P) consensus network. Each network node may maintain its local copy of a data chain and may generate a data block for updating the data chain. After a threshold number of network nodes generate the same consensus block from the data block, each network node may update its local data chain by appending the consensus block thereto.
