Underwater alumen usticum image acquisition instrument

Abstract

The invention discloses an underwater alumen usticum image acquisition instrument, and belongs to the technical field of water treatment equipment. The underwater alumen usticum image acquisition instrument comprises a shooting assembly used for shooting alumen usticum in water and an illumination assembly, the illumination assembly and the shooting assembly are arranged at intervals to form a channel, the alumen usticum can enter the channel, and the light-emitting side of the illumination assembly is arranged right opposite to the shooting direction of the shooting assembly. According to theunderwater alumen usticum image acquisition instrument provided by the invention, the illumination assembly and the shooting assembly are arranged at intervals to form the channel, so that alumen usticum can enter the channel, sparsity of alumen usticum in a view field is ensured, and the problem of alumen usticum overlapping is solved; and the light-emitting side of the lighting assembly is arranged right opposite to the shooting direction of the shooting assembly, a backlight illumination mode is formed for the alumen usticum, reflection caused by front illumination can be avoided, the shadow of the alumen usticum is shot through front illumination, the contrast ratio and shooting definition of the image can be improved, then the quality of an alumen usticum picture is improved, and theaccuracy of an image recognition result is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to an underwater alum flower image acquisition instrument. Background technique [0002] In the water treatment process of conventional waterworks, flocculants are used to coagulate the impurities in the water, so that the colloidal particles and micro suspended solids that are not easy to settle in the water form larger flocs, which is conducive to separation and precipitation from the water. The control of flocculant dosage is very important. Too much dosage will not only cause waste, but also lead to excessive chemical substances and endanger human health; too little dosage will not achieve good flocculation and sedimentation effect. The flocs are generally called alum flowers. By manually judging the size and structure of the alum flowers, the flocculation effect can be judged. However, this method relies too much on manual experience and is not efficient. ...

Problems solved by technology

Too much dosage will not only cause waste, but also lead to excessive chemical substances and endanger human health; too little dosage will not achieve good flocculation and sedimentation effect

Flocs are generally called alum flowers. By manually judging the size and structure of alum flowers, the flocculation effect can be judged. However, this method is too dependent on manual experience and is not efficient.

[0003] In recent years, digital image processing technology has been gradually applied to the observation of alum flowers. Videos or images of alum flowers are obtained through cameras, and digital image processing technology is used to analyze the characteristics of alum flowers. According to the characteristics, the coagulation effect is judged and the dosage of flocculants is modified. amount, but the water environment is complicated, and the image acquisition equipment is very demanding

In the prior art, the monitoring device mainly includes a computer, a shooting structure, a protection chamber, and a sampling frame, wherein the sampling frame includes a light source, a background plate at the front end, and a transparent window plate at the rear end; since the alum flowers in water are generally dense, If you directly use the camera to take pictures of alum flowers, then it is very likely that you will take a superimposed photo of the alum flowers, so that the correct results will not be obtained during image processing; and the conventional light source is located above and below the alum flowers, which will cause The uneven illumination of alum flowers reduces the quality of alum flower pictures and increases the difficulty of image processing, which may lead to inaccurate image recognition results
