Abstract: 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.

Abstract: A system and method of securing data, such as images, may include receiving, by an edge server operating on a local area network (LAN) and communicatively coupled to a cloud-based server, encrypted data captured and/or generated by a first device operating on the LAN.

Abstract: The disclosure relates generally to systems and methods for quickly and efficiently estimating motion of objects in a three-dimensional environment. The disclosed systems and methods include generating a voxelized map of the three-dimensional environment including voxelized objects of interest. Each voxel in the voxelized object is associated with a signature identifier that may be used to track motion of the voxelized objects at different timepoints. By creating data structures of the three-dimensional environment at different timepoints and comparing changes in the coordinate position of the voxelized objects, motion data of the voxelized objects in the three-dimensional environment may be estimated.

Abstract: A predictive system and process that predicts safety system activation in industrial environments when collaborative robots (COBOTs), automated guidance vehicles (AGVs), and other robots (individual or collectively “robots”) are interacting (i) between one another or (ii) between a robot and human. As provided herein, the predictive system is not meant to substitute traditional safety systems, but rather to detect and classify robot-to-robot and robot-to-human interactions and potential interactions thereof so as to limit or avoid those interactions altogether, thereby increasing safety and efficiency of the robots.

Abstract: 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.
