The application provides a charging port recognition and positioning method and device based on multi-modal perception, which comprises the following steps: acquiring binocular visible light images and infrared depth maps, synchronizing and pixel-level registering based on calibration external parameters to obtain RGBD data; inputting the visible light images into a detection model embedded with coordinate attention to obtain a candidate detection box; combining the geometric parameters of the detection box and local depth features to output two-dimensional correction offsets from a correction network, and correcting at least three two-dimensional feature points; establishing a two-dimensional-three-dimensional correspondence according to three-dimensional template points and outputting rotation parameters and translation parameters by differentiable PnP solving; weighting the reprojection error by using the variance output by the uncertainty branch; when the reprojection error meets the trigger condition, writing the sample into the difficult sample buffer and performing incremental updating on at least part of the parameters of the correction network and / or the uncertainty branch. The technical scheme of the application realizes stable output of the charging port pose, and improves the success rate of automatic charging alignment and plugging.

The present invention concerns a method and devices for wirelessly synchronizing at least one image displaying device and at least one image recording device, said method comprising the steps of: a) displaying a sequence of display image frames at a displaying frame rate (DFR) with said image displaying device; b) recording a sequence of recording image frames of scenery including said sequence of display image frames with said image recording device at a recording frame rate (RFR); c) synchronizing said displaying frame rate (DFR) and said recording frame rate (RFR) such that said recording frame rate (RFR) is an integer multiple or an integer fraction of said displaying frame rate; and d) adjusting a phase shift between said sequence of displaying image frames and said sequence of recording image frames such that each recording image frame captures a portion of a single displaying image frame.

The present disclosure relates to a method, a computing device and a storage medium for synchronizing time of a plurality of time domains, the method comprising: a step of transmitting, by a Precision Time Protocol (PTP) layer of the master node, a reference time pointed by a hardware clock of the master node to a Precision Time Protocol (PTP) layer of the slave node; a step of synchronizing, by the Precision Time Protocol (PTP) layer of the slave node, a hardware clock of the slave node to the reference time pointed by the hardware clock of the master node; a step of transmitting, by an offset value clock layer of the master node, an offset value (θ1) of a first time domain of the plurality of time domains to an offset value clock layer of the slave node; and a step of applying, by the Precision Time Protocol (PTP) layer of the slave node, the offset value (θ1) of the first time domain transmitted to the offset value clock layer of the slave node to the reference time pointed by the hardware clock of the slave node and thereby obtaining time of the first time domain.

This invention discloses a distributed new energy cluster adaptive power coordinated control method and related devices, relating to the field of new energy technology. The method includes: dividing the distribution network into several clusters, each managed by an edge controller; the edge controller quantifies the cluster's aggregate adjustable capability and encapsulates it into a standardized information packet; monitoring the state variables of the cluster boundary nodes to determine if an over-limit event has occurred; if so, generating a start command and synchronizing; responding to the start command, initializing improved alternating direction multiplier method parameters through a cloud coordinator; the edge controller constructs a local aggregate adjustable capability model based on the standardized information packet, enters an iterative process, and outputs optimization results; each edge controller generates control commands based on the local optimization solution in the optimization results and executes them; after verifying the elimination of the over-limit event, resetting is performed. This invention solves the problems of high communication resource consumption, weak privacy protection, poor algorithm adaptability, and insufficient control response in existing technologies.
