  • Patent number: 11562497
    Abstract: Implementations are described herein for analyzing a sequence of digital images captured by a mobile vision sensor (e.g., integral with a robot), in conjunction with information (e.g., ground truth) known about movement of the vision sensor, to determine spatial dimensions of object(s) and/or an area captured in a field of view of the mobile vision sensor. Techniques avoid the use of visual indicia of known dimensions and/or other conventional tools for determining spatial dimensions, such as checkerboards. Instead, techniques described herein allow spatial dimensions to be determined using less resources, and are more scalable than conventional techniques.

  • Patent number: 11554727
    Abstract: A vehicular vision system includes a plurality of cameras disposed at a vehicle and having respective exterior fields of view. Each camera includes an image sensor and a microcontroller having memory, and each camera is in communication with a vehicle controller. Image data captured by the image sensor of each camera is communicated to the vehicle controller. The vehicle controller communicates control data to each camera, and the communicated control data is stored in memory of each camera. With the communicated control data stored in the memory of each camera, the vehicle controller communicates a trigger signal to each camera during operation of the vehicle and vision system. Responsive to the communicated trigger signal, the microcontroller of each camera loads parameters of the control data stored in the respective memory into the respective image sensor so that the parameters of the image sensors of all of the cameras are synchronized.

  • Patent number: 11556098
    Abstract: Logical boundaries enclosing a physical area are defined. A segment of the logical boundaries is defined as a directional gate, wherein traversing the gate into the physical area is defined as an ingress and traversing the gate out of the physical area is defined as an egress. The directional gate is monitored, and ingresses and egresses are detected. An occupancy count of the physical area is maintained, based on monitoring the gate and detecting ingresses and egresses. One or more conditions are tracked in addition to the occupancy count. Artificial intelligence (AI) processing is applied to the maintained occupancy count and the additional tracked condition(s), in real-time as the monitoring, maintaining and tracking are occurring. One or more responsive actions are automatically taken as a result of applying the AI processing to the maintained occupancy count and the additional tracked condition(s).

    Abstract: In this object recognition device, an association between a first object detection result and a second object detection result is taken in a region excluding an occlusion area. When the first object detection result and the second object detection result are determined to be detection results for an identical object, a recognition result of the surrounding object is calculated from the first object detection result and the second object detection result. Thus, occurrences of erroneous recognition of an object can be decreased as compared to a conventional object recognition device of a vehicle.

  • Patent number: 11519997
    Abstract: A laser-strike detection system includes an imaging sensor mounted on a platform, and a computing device. The imaging sensor outputs image frames that are each representative of a portion of the platform at a different time, during which a laser may be striking the platform. The computing device receives the image frames, and computes a delay map that indicates time-of-arrival delays of the laser beam at points on the portion of the platform. The computing device converts the delay map to a path-length variation map by multiplying the delay map by the propagation speed of light. The computing device fits a plane to the path-length variation map constrained by a topological model of the platform. The computing device computes angular deflections in x- and y-directions based upon the fit, which angular deflections define a direction from the platform to an emitter of the laser beam.

  • Patent number: 11438570
    Abstract: The present technology relates to a data processing apparatus, a data processing method, and a program that are capable of generating calibration data for performing appropriate image processing. The data processing apparatus performs interpolation to generate calibration data for a predetermined focus position by using calibration data for a plurality of focus positions. The calibration data for the plurality of focus positions is generated from a calibration image captured at the plurality of focus positions. The calibration image is obtained by capturing an image of a known object in the plurality of focus positions with a multi-lens camera that captures an image from two or more viewpoints. The present technology is applicable, for example, to a multi-lens camera that captures an image from two or more viewpoints.

  • Patent number: 11391952
    Abstract: In one implementation, a method involves obtaining light intensity data from a stream of pixel events output by an event camera of a head-mounted device (“HMD”). Each pixel event is generated in response to a pixel sensor of the event camera detecting a change in light intensity that exceeds a comparator threshold. A set of optical sources disposed on a secondary device that are visible to the event camera are identified by recognizing defined illumination parameters associated with the optical sources using the light intensity data. Location data is generated for the optical sources in an HMD reference frame using the light intensity data. A correspondence between the secondary device and the HMD is determined by mapping the location data in the HMD reference frame to respective known locations of the optical sources relative to the secondary device reference frame.
