Provided is an infrastructure and a vehicle for communicating with the same. The infrastructure recognizes a first area and a second area, and when a proportion of the second area of the image information is greater than or equal to a reference proportion, controls first and second adjusters to change a photographing area of a camera. The vehicle recognizes a hidden area, when a proportion of the hidden area is greater than or equal to a reference proportion, transmits an adjustment command of the first camera to the infrastructure, and when the proportion of the hidden area is less than the reference proportion. The vehicle matches an image of the hidden area to second image information of the second camera to generate a top view image.

A method for aligning the field of view of a user with the field of view of a camera mounted on the user's head may include providing at least one head-mounted camera module that includes at least one sensor that in turn includes an image sensor, where the said image sensor outputs video of an area; receiving a first input from a user to expect a second input relating to the field of view; receiving the second input relating to the field of view; and aligning the field of view of the user with the field of view of the camera.

Disclosed are systems and techniques for identifying product identifiers in images. A technique can include receiving, by an edge computing device, x and y coordinates for a location of an out of stock shelf section, determining a frame of reference (FOR) based on the coordinates, the FOR including a location of a product identifier for the out of stock shelf section, determining incremental adjustments to a camera based on the FOR, instructing the camera to adjust by the incremental adjustments and capture an image of the location of the product identifier, performing image analysis on the image to identify the product identifier, determining second incremental adjustments to the camera to focus the camera on the location of the product identifier if the product identifier is not identifiable in the image, and instructing the camera to reset to original camera settings if the product identifier is identifiable in the image.

Described herein are systems and techniques for imaging inventory objects in an environment. A system can include a cart, a first fixed camera fixedly mounted on the cart at a first angle, a pan-tilt-zoom (PTZ) camera controllably mounted on the cart, a PTZ controller, and a cart controller. The PTZ controller can receive PTZ instructions from the cart controller and send engagement instructions to the PTZ camera. The cart controller can receive, from the first fixed camera, first image data that captures a first inventory object, determine, from the first image data, a spatial location of a first inventory object, generate PTZ instructions to cause the PTZ camera to capture the first inventory object, transmit the PTZ instructions to the PTZ controller, and receive PTZ image data that captures the first inventory object.

An electrical wall plate may include one or more of the following features. A face plate comprising at least one electrical device opening extending through the face plate. At least one box mounting screw opening configured to receive at least one box mounting screw to fasten the face plate to an electrical device. A power connector extending in a direction away from the face plate and configured to connect with the electrical device. A camera integrated with the face plate and in electrical connection with the power connector and configured to operate by power obtained from the electrical device when the power connector is connected to the electrical device. A camera movement control feature may comprise externally-engageable components coupled to the face plate and configured to movably position the camera or a camera lens by pan or tilt to point in different directions.

Techniques of streaming data processing for hybrid online meetings are disclosed herein. In one example, a method includes receiving, at the remote server, a video stream captured by a camera in the conference room. The video stream captures images of multiple local participants of an online meeting. The method also includes determining identities of the captured images of the multiple local participants in the received video stream using meeting information of the online meeting and generating a set of individual video streams each corresponding to one of the multiple local participants. The set of individual video streams can then be transmitted to the second computing device corresponding to a remote participant of the online meeting as if the multiple local participants are virtually joining the online meeting.

Devices, systems and methods for operating a rear-facing perception system for vehicles are described. An exemplary rear-facing perception system contains two corner units and a center unit, with each of the two corner units and the center unit including a camera module and a dual-band transceiver. A method for operating the rear-facing perception system includes pairing with a control unit by communicating, using the dual-band transceiver, over at least a first frequency band, transmitting a first trigger signal to the two corner units over a second frequency band non-overlapping with the first frequency band, and switching to an active mode. In an example, the first trigger signal causes the two corner units to switch to the active mode, which includes orienting the camera modules on the center unit and the two corner units to provide an unobstructed view of an area around a rear of the vehicle.
