OpenCV-based Recognition Method for Computer Interlocking Host Computer Interface

In order to improve the efficiency of identifying the operation of computer interlocking host computer interface and promote the improvement of automation, combined with the display standards and requirements of the host computer interface, this paper proposes an image analysis method for the host computer interface based on Open CV. The method accurately extracts the coordinate information on the screen by quantifying the geometric features of various types of signal devices in the host computer interface. Through this process, it can realise the automatic identification, obtain the whole station's signal layout map from the image input, and make preparations for the subsequent automated test.
