dust measuring method in air using photographing digital image

摘要

The present invention relates to a technique for photographing a specific space in a state of illuminating bright light with respect to a specific space in the air and measuring the amount of dust located in the specific space, And analyzing the image of the image taken in the space, thereby quantifying the amount of dust in the air of the specific space and informing the user of the amount of dust. Particularly, in taking a specific space in which air enters and exits, the light irradiated to the specific space is reflected by the adjacent inner wall to suppress the entry into the specific space as much as possible, It is a technology that can accurately reflect the shot image and accurately perform dust measurement accordingly. According to the present invention, the amount of dust in the air is measured and quantified, so that the user can accurately determine the degree of contamination of the room air according to the amount of dust in the air.;
