Embodiment 1
[0072] On the basis of the above content, this embodiment can build a moving contact pressure measurement model, specifically, the following steps:
[0073] Collect at least two complete images of the static contacts of the relay;
[0074] The pictures corresponding to each set of complete images are extracted to form a corresponding picture set.
[0075] Extract some random pictures from any set of pictures;
[0076] Cut random pictures to make corresponding static contact templates;
[0077] Get three pictures of different states in any set of pictures, including the picture of no contact between the moving contact and the static contact, the picture of stable contact between the moving contact and the moving contact, and the picture of only the moving contact and the moving contact Steady exposure to pictures.
[0078] Obtain the sub-areas corresponding to each picture in different states;
[0079] Use the static contact template to traverse the sub-regions of each pict...
Embodiment 2
[0106] On the basis of the above content, this embodiment can build a dynamic contact pressure measurement model, specifically, the following steps:
[0107] Collect at least two complete images of the static contacts of the relay;
[0108] The pictures corresponding to each set of complete images are extracted to form a corresponding picture set.
[0109] Extract some random pictures from any set of pictures;
[0110] Cut random pictures to make corresponding static contact templates;
[0111] Get three pictures of different states in any set of pictures, including the picture of no contact between the moving contact and the static contact, the picture of stable contact between the moving contact and the moving contact, and the picture of only the moving contact and the moving contact Steady exposure to pictures.
[0112] Obtain the sub-areas corresponding to each picture in different states;
[0113] Use the static contact template to traverse the sub-regions of each pic...
Embodiment 3
[0172] Please refer to figure 2 The shown flow diagram of a system based on the image processing-based contact pressure measurement model construction method described in Embodiment 1 and Embodiment 2 provided by the present application includes: an image acquisition module 101 and an image processing module 102 , tracking module 103, computing module 104, storage module 105 and display module 106;
[0173] The image collection module 101 is used to obtain a picture collection of the static contact movement process of the relay, and transmit it to the picture processing module 102;
[0174] The picture processing module 102 is used to obtain the static contact template and three pictures of different states according to the picture set, so as to determine the target area;
[0175] The tracking module 103 is used to track the movement trajectory of the static contact within the target area, determine the target coordinate sequence, and send it to the calculation module 103; ...
