Abstract
An imaging system comprising circuitry configured to obtain (S2) image data of a scene that is illuminated with patterned light (PL), determine (S5, S6) bright regions and dark regions based on the image data, and relate image information related to the bright regions to image information related to the dark regions in order to determine characteristics of atmospheric aerosol particles (AP).
Claims22
An imaging system comprising circuitry configured to:
- obtain image data of a scene that is illuminated with patterned light,
- determine bright regions and dark regions based on the image data,
- obtain image information related to the bright regions and image information related to the dark regions,
- calculate an intensity ratio as a ratio of an intensity value associated with the bright regions to an intensity value associated with the dark regions based on the image information related to the bright regions and the image information related to the dark regions, and
- compare the intensity ratio with a threshold value in order to determine if atmospheric aerosol particles are present.
