Abstract
An analyzing apparatus includes a collection filter, a two-dimensional sensor, and a calculation unit. The collection filter collects fine particulate matter included in the air. The two-dimensional sensor obtains collection image data including a collection area of the collection filter in which the fine particulate matter is collected. The calculation unit calculates data relating to content of the colored particulate matter included in the collection area based on the collection image data.
Claims12
An analyzing apparatus comprising:
- a collection filter collecting particulate matter included in the atmosphere;
- a two-dimensional sensor obtaining two-dimensional collection image data including two-dimensional first image data indicating a collection area of the collection filter in which the particulate matter is collected, and two-dimensional second image data indicating a non-collection area of the collection filter in which the particulate matter is not collected;
- and
- a calculation unit configured to calculate data relating to content of colored particulate matter included in the collection area based on an integrated value of a first luminance of pixels in the first image data, or based on the first luminance and a second luminance of pixels in the second image data.
A system comprising:
- an analyzing apparatus comprising:
- a collection filter collecting particulate matter included in the atmosphere;
- a two-dimensional sensor obtaining two-dimensional collection image data containing two-dimensional first image data indicating a collection area of the collection filter in which the particulate matter is collected, and two-dimensional second image data indicating a non-collection area of the collection filter in which the particulate matter is not collected;
- and
- a calculation unit configured to calculate data relating to content of colored particulate matter included in the collection area based on an integrated value of a first luminance of pixels in the first image data, or based on the first luminance and a second luminance of pixels in the second image data;
- and
- a source identifying device configured to identify a source of the particulate matter based on data that is used to identify a source of the particulate matter and data obtained by the analyzing apparatus.
An analyzing method comprising the steps of:
- collecting particulate matter included in the atmosphere on a collection filter;
- obtaining two-dimensional collection image data containing two-dimensional first image data indicating a collection area of the collection filter in which the particulate matter is collected, and two-dimensional second image data indicating a non-collection area of the collection filter in which the particulate matter is not collected;
- and
- calculating data relating to content of colored particulate matter included in the particulate matter based on an integrated value of a first luminance of pixels in the first image data, or based on the first luminance and a second luminance of pixels in the second image data.
A non-transitory computer readable storage product having stored data representing a program for causing a computer to perform an analyzing method comprising the steps of:
- collecting particulate matter included in the atmosphere on a collection filter;
- obtaining two-dimensional collection image data containing two-dimensional first image data indicating a collection area of the collection filter in which the particulate matter is collected, and two-dimensional second image data indicating a non-collection area of the collection filter in which the particulate matter is not collected;
- and
- calculating data relating to content of colored particulate matter in the atmosphere based on an integrated value of a first luminance of pixels in the first image data, or based on the first luminance and a second luminance of pixels in the second image data.
