Machinery manufacturing industry is the basic development field of China, which is related to the development of many aspects and the improvement of China's comprehensive national strength. In the key process of the machinery manufacturing industry, it not only pays attention to the development ability and the control level of all aspects, but also pays attention to the application of the internal environment creation and development concept of enterprises. Based on this, this paper mainly discusses the development problems and controllable main processes in the machinery manufacturing industry, aiming to provide a basis for related research.展开更多

The algorithm include an image processing with a binarzation method, image grab for a vehicle with high speed, character isolator one by one, and neural network algorithm. The techniques include vehicles sensing, image garb control, vehicle license location, lighting and optic character recognition. The system is much more robust and faster than the traditional thresholding method.展开更多
