Abstract

The invention provides a brightness correction method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining first brightness values of a plurality of first images, the plurality of first images being images obtained by collecting projection images of a plurality of second images; acquiring a brightness correction curve between the first brightness value and pre-acquired second brightness values of the plurality of second images; and correcting the brightness of the plurality of first images by using the brightness correction curve. According to the invention, the brightness accuracy of the plurality of first images can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a brightness correction method, device, electronic equipment and readable storage medium. Background technique [0002] Phase measurement profilometry is widely used in industrial inspection, profiling of cultural relics, medical plastic surgery and reverse engineering and other fields. This technology calculates the package phase value containing the three-dimensional information of the surface of the measured object by collecting multiple frames of fringe images with a certain phase shift. Using multi-frequency phase shifting or combining with other encoding methods to realize phase unwrapping, so as to obtain absolute phase information for 3D reconstruction of the measured object. [0003] In phase measurement profilometry, ideally, the brightness of the projected image of the projection device is linearly related to the brightness of the image obtained ...
