Fog column automatic detection system based on machine vision

Abstract

The invention discloses a fog column automatic detection system based on machine vision. The system comprises a camera calibration module used for calibrating image acquisition devices in a fog column image acquisition module, the fog column image acquisition module used for acquiring images of fog columns sprayed by a nozzle, a fog column image processing module used for processing the fog column images acquired by the fog column image acquisition module, a detection data analysis module which is used for acquiring the coverage area and the maximum width of the fog column according to the information acquired by the fog column image processing module, and a detection result display module which is used for displaying a related result acquired by the detection data analysis module, wherein the detection data analysis module obtains the boundary line of the outer contour of the fog column through a polynomial fitting algorithm and then obtains the coverage area and the maximum width of the fog column. According to the system, automatic measurement of the fog column can be completed, the problem that the randomness of manual measurement is large is solved, and the system is high in detection precision, good in objectivity, high in efficiency and easy and convenient to operate and has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of fog column image processing, and relates to a machine vision-based automatic detection system for fog columns, in particular to an automatic detection system for fog columns that can automatically collect the coverage area and maximum width of nozzle sprayed fog columns. Background technique [0002] In actual production, there are many processes that require the use of high-pressure spray to spray mist on the surface of workpieces, such as spraying and coloring of body panels, cleaning of workpiece surfaces, cooling of steel plants, etc. Performance has a critical impact. However, on the automated assembly line, it is often impossible to measure and detect the fog column manually. Taking the spraying and coloring of body panels as an example, if manual inspection is used, it will take a lot of time to inspect, and a lot of manpower and material resources will be spent, and the inspection results are cha...
