A Method for Imaging Panorama Image of Tube Reactor Furnace

Abstract

A tubular reacting furnace hearth panoramic image imaging method disclosed by the present invention comprises the steps, such as the image pre-processing, the view angle transformation, the image blind area reproduction, the image splicing, the image fusion, the temperature color coding, etc. According to the tubular reacting furnace hearth panoramic image imaging method provided by the present invention, a hearth panorama top view image is obtained by a plurality of set monitoring probes, and then a hearth local top view image is transformed into a front view image rapidly by combining the hearth spatial size and the spatial solid angles of the pixels of the monitoring probes, thereby visually reflecting the hearth internal real information, and being good in visual effect. According to the method, a tubular reacting furnace hearth panoramic image can be extracted effectively and rapidly, thereby retaining the real-time information of a furnace tube furthest; the infrared radiation information can be extracted by the panoramic image, so that the furnace wall surface temperature of the furnace tube can be calculated accurately, the hearth temperature information and the change variation trend can be displayed panoramically, and the foundation is laid for the tubular reacting furnace panoramic temperature field detection.

Description

technical field [0001] The invention relates to imaging technology, in particular to a furnace panorama image imaging method of a tubular reaction furnace, which belongs to the field of chemical equipment operation detection. Background technique [0002] The tube reactor is the core equipment of chemical production. The real-time status information of the furnace tube plays a vital role in the safety supervision and efficient production of the entire reaction process. However, the internal situation of the tube reactor is complicated and is always heated at high temperature. State, unable to observe closely. With the development and maturity of image processing technology, there is a new way to obtain the hearth image of tubular reactor. [0003] Patent CN200410060961 discloses a real-time monitoring device for a three-dimensional temperature field in a coal-fired boiler. By arranging a plurality of color CCD cameras layered along the furnace height, the pulverized coal co...

Problems solved by technology

The literature "Design and Research of Blast Furnace Charge Level Automatic Imaging Control System" designed a "visualized" blast furnace charge level monitoring system, and provided image stitching of the area of ​​interest to obtain a complete real-time image of the entire blast furnace charge level. The image of each material surface stitched by the method is a front view, and there are obvious characteristic areas, depending on the shooting angle and characteristic information of the image, it has great limitations, and cannot adapt to the situation where the partial images of the tubular reactor are highly similar
