Embodiment 1

[0049] This embodiment provides a method for identifying the state of the platen, which is used to identify the state of the platen, and is realized by image recognition technology, achieving the effect of identifying various states of the platen.

[0050] Such as figure 1 As shown, the method includes the following steps:

[0051] S1: Collect state images of the platen and build a template library.

[0052] The construction process of the template library is attached figure 2 shown. Collect the status image of a certain type of platen, then grayscale and filter the image to obtain the processed image. According to the processed image, set the state of the platen, so that the sample image in the template library matches the state of the platen. Store the processed image and platen state into the database to complete the establishment of the template library.

[0053] Among them, the image of the platen is grayscaled, and the weighted average method is used for the grayscal...

Abstract

The invention relates to a pressing plate state recognition method, and the method comprises the steps: S1, collecting a state image of a pressing plate, and constructing a template library; s2, shooting a to-be-detected pressing plate image, and performing image segmentation on the to-be-detected pressing plate image to obtain a pressing plate segmentation image; s3, traversing the template library, and carrying out template matching on the pressing plate segmentation image; and S4, outputting the corresponding state of the pressing plate image most matched with the pressing plate segmentation image in the template library, namely the state corresponding to the pressing plate to be tested. The method does not need to extract the image features of the relay protection and automatic devicepressing plate, is high in recognition speed, and solves a problem that the recognition rate is low because the state of the pressing plate is recognized through an edge in a conventional scheme. According to the method, state recognition can be carried out on the pressing plates of different specifications, the pressing plates of different shapes can be recognized, the recognition precision can be improved by increasing the number of template samples, calculation is simple, and the speed is high.

Description

technical field [0001] The invention relates to the field of power protection devices, and more specifically, to a method for identifying the state of a pressing plate. Background technique [0002] At present, there are the following methods for relay protection and automatic device pressure plate state recognition: (1) By extracting the edge features of the shape of the pressure plate, such as for a rectangular pressure plate, by identifying the contour features of the image, extracting the straight line, and then the pressure plate Rectangular recognition is done, and the wool and thorns on the straight edge are interfered with, and finally the minimum rectangle of the pressing plate is obtained, and its inclination angle is calculated to obtain the state of the rectangular pressing plate. This method can only be used for rectangular platens, and has limitations in identifying the state of square or triangular platens. Therefore, it is necessary to perform different image...
