Optoelectronic sorting system imaging parameter adaptive control method based on real-time feedback

Abstract

This invention discloses an adaptive control method for imaging parameters of a photoelectric sorting system based on real-time feedback, relating to the field of photoelectric sorting technology. The method includes: acquiring imaging region feedback data and illumination unit light attenuation feedback data; separating locally bright areas and non-bright normal areas from the imaging region feedback data; and forming a bright spot feedback traction quantity based on the brightness change, area ratio, and overall brightness feedback change of the locally bright areas; and determining the correspondence between the brightness change direction of the locally bright areas and the overall brightness feedback change direction of the imaging region based on the bright spot feedback traction quantity to form a bright spot feedback traction result. This invention, by forming the bright spot feedback traction quantity based on the brightness change, area ratio, and overall brightness feedback change of the locally bright areas, can quantitatively determine the traction effect of locally bright areas on the overall brightness feedback change direction of the imaging region.
