    摘要: An image processing method for flame monitoring is based on the formation of a video signal characteristic to the combustion process. In accordance with the method, the flame is monitored by each fire-box camera essentially from its side, whereby the video signal is adapted to cover at least an entire ignition area of a single burner, the video signal is continually processed to define the average intensity level corresponding to the steepest intensity gradients, and for each averaged level, the corresponding spatial or time coordinates of the continuous video signal, which define the location of the ignition area, are determined. The method extracts from the ignition and combustion process abundant information helpful in the control of combustion.

    摘要: A method for generating real-time control parameters by a video camera for smoke-generating combustion reactions is disclosed. In accordance with the method, a video camera is used for obtaining a video signal, which is digitized and filtered temporally and spatially. The digitized video signal is divided on the basis of its signal level distribution into signal subareas to reduce the quantity of processed information. The picture elements belonging to the same subarea are combined into contiguous image areas representing a certain signal level, the subareas are combined into an integrated image, subsequent images are averaged to eliminate random disturbance, and the averaged image is displayed on a display device. This method facilitates the real-time monitoring of a combustion process.
