| Abstract: | In order to quickly and accurately identify the coal car number during the loading process of the coal railway, an identification method of coal car number based on machine vision was put forward. Firstly, the connected region extraction and projection segmentation method were combined to realize rough positioning and fine segmentation of the car number;secondly, the broken characters in the image were divided twice;finally, the classification model based on BP neural network was constructed to identify the car number. |
