Backlight interference resistance identification method for lightning arrester leakage ampere meter

The invention relates to a lightning arrester leakage ampere meter anti-backlight identification method based on gradient direction characteristics, and the method comprises the following steps: collecting an original image of a lightning arrester leakage ampere meter, and carrying out the preprocessing of the original image, and obtaining an enhanced image; obtaining a direction gradient histogram of pixels in the enhanced image, and processing to obtain gradient direction features of the whole enhanced image; the gradient direction features of the lightning arrester leakage ammeter enhanced image are obtained through the above steps as samples, and the readings of the ammeter are added to the samples as sample labels; the gradient direction features of all the samples serve as input, the sample labels serve as output, an SVM classifier is trained, and a trained reading recognition model is obtained; obtaining an original image of a leakage ammeter of a target lightning arrester, and obtaining ...

Instrument image registration method and device based on texture registration

The invention relates to an instrument image registration method based on texture registration. The method comprises the following steps: obtaining a standard image and a to-be-registered image; preprocessing the standard image and the to-be-registered image; respectively extracting texture features of the standard image and the to-be-registered image to obtain a first texture feature map and a second texture feature map; respectively extracting texture feature points of the first texture feature map and the second texture feature map to obtain a first feature point set and a second feature point set; calculating the similarity between each first feature point and each second feature point; performing matching judgment on the first texture feature map and the second texture feature map according to the similarity; if the matching judgment result is successful, continuing the next step; otherwise, re-acquiring the image to be registered; selecting N matching pairs with the highest similarity ...

Auxiliary method and terminal for butt joint of circuit breaker transfer trolley and switch cabinet

The invention discloses an auxiliary method and terminal for butt joint of a circuit breaker transfer trolley and a switch cabinet, and the method is characterized in that the method comprises the steps: obtaining image data collected by an auxiliary alignment camera, and recognizing a butt joint target hole in the switch cabinet in the image data; the butt joint target hole is calibrated through the left auxiliary alignment camera and the right auxiliary alignment camera, and three-dimensional space coordinates of the hole under the left auxiliary alignment camera are obtained through calculation; according to the transformation matrix of the center of the transfer trolley and the auxiliary alignment camera on the left side, the relative pose relation between the center of the transfer trolley and the butt joint target hole is obtained; carrying out manual adjustment prompt according to the relative pose relationship; according to the method, the docking target hole is identified and the ...

Abnormality detection method and terminal for circuit breaker transfer trolley

The invention discloses a circuit breaker transfer trolley abnormity detection method and a terminal. The method comprises the following steps: acquiring pressure data of a pressure sensor and displacement data in a preset first time period in real time; judging whether foreign matters are pressed or not according to pressure sensor data and displacement data, and identifying whether the vehicle body is inclined or not according to image data acquired by the auxiliary alignment camera; if it is judged that the foreign matter is pressed or the vehicle body inclines, a user is reminded; according to the method and the terminal for detecting the abnormity of the circuit breaker transfer trolley, whether the trolley body presses the foreign matter is judged according to the pressure sensor data and the displacement data, and the inclination of the trolley body is detected according to the image data, so that the abnormity possibly existing in the butt joint process of the transfer trolley and ...
