Abstract: Provided are an interaction method and apparatus in a live streaming room, and a device and a storage medium. The method comprises: in response to a trigger operation for a preset duet entry on a live streaming room page, jumping from the live streaming room page to a camera capture page, wherein a host portrait cutout corresponding to the live streaming room page is displayed on the camera capture page and a capture control is provided on the camera capture page acquiring multimedia information captured by a camera, in response to a trigger operation for the capture control on the camera capture page, wherein the multimedia information comprises an image or a video; and synthesizing the multimedia information with the host portrait cutout to obtain a duet multimedia product.

Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: A method for synchronized and distributed processing multi-channel image and video stream based on 5G environment is provided, including: transmitting multi-channel the same pulse signals to a data collecting circuit by a pulse transmitter, the data collecting circuit transmits the pulse signal to an image capturing circuit, and the image capturing circuit triggers a camera capturing system to start to simultaneously capture images and video stream. Distributing multi-channel traffic of the cameras via distributed edge computing and distribution processing, so as to locally process the captured images and video stream directly. Such that, the bandwidth pressure is significantly reduced and the risk of terminal sensitive data information privacy leakage is reduced, too.

Abstract: A method for capturing images on a super-large-scale power equipment (SLSPE) based on a camera free viewing angle is provided, including: determining a first range of the SLSPE and a second range of the camera free viewing angle of each of installed cameras; determining a total number, positions, angles, focal lengths, apertures of the cameras, so as to make, by a synchronous calibration, the combined capturing region fully cover the SLSPE according to the first range and the second range; capturing synchronously images and video and adding timestamps to the captured images and video; performing classified packaging to the captured images and video according to the timestamps, so as to group a plurality of specific images and video captured at the same time into a package; and performing seamlessly splicing on the specific images and video of the package to obtain a seamlessly spliced overall view of the SLSPE.

Abstract: A computer-implemented method for predicting coal quality of coal mill based on neural network is provided. The method includes: establishing a prediction model based on a neural network structure; importing cleaned coal mill data for model training; connecting the trained prediction model with a distributed control system (DCS) in real time; calculate online the running coal type of the coal mill; and determining the real-time running coal quality of the coal mill according to the calculation results.
