Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0040] Such as figure 1 As shown, an automatic extraction method of transmission line components based on UAV inspection images, the specific steps include:
[0041] 1) Image reading: read the inspection image data, perform zoom processing and perform RGB channel data separation, histogram statistics and other data calculations on the color image, as the original data for post-processing;
[0042] 2) Use the prewitt operator to traverse the image and calculate the edge information of the image;
[0043] 3) The image is divided into blocks, the characteristics of the image in each image block are analyzed, and similar features are aggregated to form a feature block;
[0044] 4) According to the inherent attributes of the transmission line components, the feature blocks are analyzed for characteristics such as connectivity, parallelism, and intersection...
