Abstract: A remote follow spot system includes a remote controller that has separately movable parts that are movable in two orthogonal directions, and a display attached to one of said two separately movable parts. The display receives a video feed from a controlled light, that is controlled to move in the same directions as remote controller. The display hence shows the field of view where the light is pointing. In this way, an operator of the follow spot can control the light without physically being near the light.

Abstract: Various embodiments disclosed herein include techniques for adjusting the lateral position of a default field of view of a camera. The camera may change the lateral position of its field of view by creating relative movement between an image sensor and a lens of the camera, and may maintain the camera's field of view to the default field of view when the camera is stationary. In some embodiments, the lateral position may be set using orientation information associated with the camera. In other embodiments, the lateral position may be set using position information associated with a target object.

Abstract: Systems, video cameras, and methods for using audio sensors to control surveillance video capture are described. A video camera and audio sensor are deployed so that the audio sensor has an audio field that is at least partially outside the field of view of the video camera. The audio sensor collects audio data from the audio field and a controller for the video camera uses audio events from the audio data for modifying the video capture operations of the video camera. Video data is then captured based on the modified video capture operations, such as initiating video capture, changing the video capture rate, or changing the camera position.

Abstract: Devices, methods, and non-transitory computer readable media are disclosed herein to repair or mitigate the appearance of unwanted reflection artifacts in captured video image streams. These unwanted reflection artifacts often present themselves as brightly-colored spots, circles, rings, or halos that reflect the shape of a bright light source in the captured image. These artifacts, also referred to herein as “ghosts” or “green ghosts” (due to often having a greenish tint), are typically located in regions of the captured images where there is not actually a bright light source located in the image. In fact, such unwanted reflection artifacts often present themselves on the image sensor across the principal point of the lens from where the actual bright light source in the captured image is located. Such devices, methods and computer readable media may be configured to detect, track, and repair such unwanted reflection artifacts in an intelligent and efficient fashion.

Abstract: An image pickup system according to embodiments includes an image pickup unit, a receiving unit, an operation unit, and a determination unit. The image pickup unit picks up an optical image formed by an optical system by means of an image pickup element to obtain an image. The receiving unit receives a radio signal including unique information transmitted from a transmitter to output the received signal. The operation unit operates an arrival angle of the radio signal based on the received signal. The determination unit determines, based on the arrival angle, whether or not the transmitter is within an angle of view of the image.

Abstract: Example implementations include a method, apparatus and computer-readable medium for person detection by a computer device, comprising receiving a plurality of video frames from a camera located in an environment, wherein the video frames include a depiction of a person in the environment. The implementations further include identifying attributes of the person from the video frames and comparing the attributes with attribute entries in a database of suspicious persons, wherein the database of suspicious persons includes attributes of a plurality of persons associated with an alert in the environment. The implementations include retrieving a profile indicative of an alert history of the suspicious person in response to determining a match between the attributes of the person and an entry in the database corresponding to a suspicious person, and transmitting, to a second computer device, the retrieved profile and a notification that indicates that the suspicious person is in the environment.

Abstract: A system is disclosed that comprises a camera module and a control and evaluation unit. The camera module is designed to be attached to the surveying pole and comprises at least one camera for capturing images. The control and evaluation unit has stored a program with program code so as to control and execute a functionality in which a series of images of the surrounding is captured with the at least one camera; a SLAM-evaluation with a defined algorithm using the series of images is performed, wherein a reference point field is built up and poses for the captured images are determined; and, based on the determined poses, a point cloud comprising 3D-positions of points of the surrounding can be computed by forward intersection using the series of images, particularly by using dense matching algorithm.

Abstract: Techniques for video processing using a topological map are disclosed. Program instructions stored on a computer-readable medium may be executable to receive data indicative of an active area of interest detected within a video frame captured by a detection system, and based upon one or more inclusion criteria, include the active area of interest within a stack of previously identified active areas of interest. The stack may occupy a primary frame within a two-dimensional video space. The instructions may be further executable to update a topological map of the two-dimensional video space based upon the stack, identify within the topological map a two-dimensional region that satisfies a density threshold, and adjust framing of a primary imaging camera based upon the two-dimensional region.
