The present application provides an image processing method, device and storage medium, comprising: acquiring a to-be-tested image of each to-be-tested object in a plurality of same to-be-tested objects, acquiring a definition difference value between a first target region of a first to-be-tested image and a second target region of a second to-be-tested image, acquiring a target parameter according to the definition difference value, and if the target parameter is greater than a target threshold, determining that the first target region and / or the second target region is an image blur region. The present application compares the definition difference value between the target regions at the same position in different to-be-tested images to determine the image blur region, automatically determines the image blur region, improves the identification efficiency of the image blur region, avoids image blur judgment errors caused by background color difference, improves the accuracy of image blur region determination, and the identified image blur region can be subsequently adjusted smoothly to achieve clear detection.

The utility model relates to a pull ring detection technical field, concretely relates to a pull ring detection device. The pull ring detection device, include: conveying assembly, conveying assembly is used for conveying jar body, detection assembly, detection assembly sets up on conveying assembly, detection assembly includes image acquisition structure, image acquisition structure has the end with pull ring to jar body orientation, to make image acquisition structure obtain jar body pull ring's image, control system, control system has controller and man -machine interface, controller is connected with image acquisition structure, man -machine interface and conveying assembly signal respectively. Through setting up image acquisition structure and control system, the image that controller can gather through image acquisition structure judges whether the pull ring of jar body that passes through image acquisition structure on conveying assembly has the defect, detects through the controller, effectively has improved the detection efficiency, has reduced the labor intensity.

The application discloses a method for preventing grade jumping trip of multi-point fault of multi-power distribution network, after detecting the fault, real-time calculation and record of the fault power direction, when the fault occurs in the positive direction of protection, sending the blocking signal to the bus side, when the fault occurs in the reverse direction of protection, sending the blocking signal to the tie side, when the detected fault power direction element only has a single direction, keeping the blocking signal output unchanged, when the positive direction of the fault power element and the reverse direction of the fault power element are detected at the same time, according to the power element direction and the received signal, adjusting the blocking signal output, not receiving the blocking signal, blocking release or receiving the blocking signal but exceeding the total timeout, the protection action outlet. The scheme is simple in configuration and clear in structure, through the fault power direction element judgment and the protection blocking signal, the relay blocking signal and the release blocking signal interaction, the selectivity of the protection action is ensured, the fast positioning and reliable isolation function of the multi-point fault of the multi-power distribution network are realized.
