Example 1
Referring to fig. 1 to 4, an embodiment of the present invention provides a real-time high-precision early warning method for distribution network operation based on AI vision, including:
s1: collecting a panoramic image of a working environment, constructing a relative position coordinate system based on the image and acquiring a relative position conversion matrix.
Furthermore, cameras equipped with a plurality of field distribution control balls arranged in a power distribution field are used for shooting live working scenes so as to acquire a panoramic image of a working environment in a monitoring area of the working field.
Furthermore, the collected panoramic image is used as a reference image, one distributed control ball in the reference image is selected as an origin, a relative position coordinate system is constructed according to relative position information among the plurality of distributed control balls, and further the position coordinate information of each pixel point in the reference image is obtained based on the constructed relative position coordinate system.
Furthermore, the reference image is corrected based on the image shot by the cloth control ball;
specifically, firstly, the internal parameters and distortion coefficients of all cameras need to be calculated and calibrated through a calibretanecamra function in opencv; then, correction is carried out through undistort function in opencv.
It should be noted that, the image taken by the distribution control ball at the present location of the distribution network operation is not a top view in the air, but a picture with a certain inclination angle with the ground; therefore, a panoramic image of the working environment formed by splicing the pictures collected by the plurality of control balls has certain distortion, and in order to ensure the accuracy of the reference image, the panoramic image needs to be corrected by using the function of opencv, so that the coordinate accuracy of the panoramic image can be improved.
Furthermore, a plurality of key points are selected from the shot image, and a relative position conversion matrix between the two planes is calculated by using a findHomography function in opencv according to relative position coordinates of the key points on the shot image and the reference image.

It should be noted that the reason for performing the work site environment video recognition using the yolo target detection model is to remove the detection video stream of the worker and the live equipment with low confidence.
Furthermore, when the same video picture of the operator and the charged equipment is successfully detected, the charged voltage data of the equipment is acquired through a background system; and if the voltage data is not 0, respectively acquiring the ROI area information of the operator and the charged equipment at the moment.
It should be noted that, when the voltage of the distribution network operation site is 0, the detection of the constructors and the live equipment does not need to be performed by wasting the computing resources; when the voltage is greater than 0, in order to ensure the safety of the distribution network operation constructors, the distance between the constructors and the electrified equipment needs to be detected; therefore, the voltage of the distribution network operation site needs to be judged before the ROI is acquired.
S3: and determining coordinate information of the operator and the electrified equipment by using the relative position matrix and the auxiliary positioning equipment.
Further, the center point of the obtained ROI region is used to obtain the position coordinates of the center point of the region corresponding to the reference map through a relative position matrix, wherein the relative position coordinates of the center point of the ROI region of the operator are expressed as:
Figure BDA0003915320210000061
the relative position coordinates of the central point of the ROI of the charged equipment are as follows:
Figure BDA0003915320210000062
furthermore, the map information is registered by using the positioning auxiliary equipment, so that the three-dimensional coordinate information of the live equipment and the operator is acquired.
It should be noted that the positioning assistance device includes UWB, beidou, and the like map positioning devices for determining position information.
It should also be noted that the position information of the live-line equipment and the operator is acquired by combining the yolo target detection and the auxiliary positioning equipment, so that the acquired three-dimensional coordinate information of the live-line equipment and the operator is more accurate, and the accuracy of the early warning of the dangerous area is further improved.
Furthermore, mapping the three-dimensional coordinate information of the operator and the charged device to a two-dimensional coordinate system to obtain two-dimensional coordinates of the operator and the charged device respectively, where the two-dimensional coordinates of the operator are:
Figure BDA0003915320210000071
the two-dimensional coordinates of the charged device are:
Figure BDA0003915320210000072
s4: and calculating the distance between the operating personnel and the live equipment by using a Gaussian distance formula, comparing the distance with the safety distance, and performing dangerous area early warning based on the comparison result.
Further, using the Gaussian distance formula
Figure BDA0003915320210000073
And calculating the distance between the operator and the electrified equipment.
Further, the calculated distance is compared with a preset safety distance for determining whether the operator is in the dangerous area.
Note that the determination etalon body is: if the calculated distance is not greater than the safety distance, judging that the operator is adjacent to or spans the safety distance during operation, and sending a real-time early warning signal to the operator in the dangerous area; and if the calculated distance is greater than the safety distance, judging that the operator is not close to the dangerous area during operation, and continuing to perform power distribution network operation.

When an operator enters a monitoring area, the distance between the operator and a charged object is calculated based on a three-dimensional coordinate positioning algorithm of vision, and position information is assisted and calibrated according to a UWB chip carried by the charged operator. And calculating the linear distance of the operator and the charged object on a two-dimensional plane according to the coordinates of the operator and the charged object, and when the distance between the operator and the charged device does not accord with the background voltage grade data and the corresponding safe distance, starting to give an alarm by the early warning system.
