Abstract

The invention relates to the technical field of size detection, in particular to a boiler part size detection method based on image processing. The method comprises the following steps: setting a sliding window to traverse an acquired top view image of a boiler grate, denoising the first window, in a window sliding process, taking a midpoint pixel point of a previous row of a target window as a reference value, constructing a reference index of the target window, and performing window-by-window filtering operation by utilizing the reference index of each target window to obtain a filtering result; obtaining a de-noised image of the top view image; edge extraction is carried out on the denoised image, continuous points in the edge are screened out, to-be-connected edge segments are obtained, and the adjacent to-be-connected edge segments are connected by using the mathematical property of a circle to obtain edge information; performing Hough circle detection on the edge information to obtain an optimal detection circle; and obtaining a characteristic index of the optimal detection circle, constructing a standard degree analysis model according to the characteristic index, and judging whether the current fire grate size is qualified or not. According to the embodiment of the invention, the accuracy of size detection can be improved.

Description

technical field [0001] The invention relates to the technical field of size detection, in particular to a method for size detection of boiler parts based on image processing. Background technique [0002] The grate is the component in a boiler or industrial furnace that stacks solid fuel and burns it efficiently. The whole grate mainly includes two parts: the frame and the grate sheet. The grate sheet is usually made of cast iron. After assembly, the necessary ventilation gaps are maintained between the sheets. So that the air enters the fuel layer through the gap and burns. After burning out, the ash and slag are discharged manually or mechanically. [0003] Boiler grate is a steel smelting structure, also called boiler grate. When the shape and size of the produced grate are abnormal, it will not be put into the corresponding boiler for use, resulting in a waste of resources. At present, the manual method is generally used for the size detection of boiler grate, but the...
