Abstract

The present application provides a brightness correction method, device, electronic equipment, and readable storage medium. The method includes: acquiring first brightness values ​​of a plurality of first images, the plurality of first images being a pair of a plurality of second images The image obtained by collecting the projection image; obtaining a brightness correction curve between the first brightness value and the second brightness values ​​of the plurality of second images acquired in advance; using the brightness correction curve to correct the plurality of Brightness of the first image. The present application can improve brightness accuracy of the plurality of first images.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a brightness correction method, an apparatus, an electronic device, and a readable storage medium. Background technique [0002] Phase measurement profilometry is widely used in industrial inspection, cultural relic profiling, medical shaping and reverse engineering. This technology calculates the phase value of the package containing the three-dimensional information on 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, the phase unwrapping is realized, so as to obtain the absolute phase information for the three-dimensional reconstruction of the measured object. [0003] In phase measurement profilometry, ideally, the brightness of the projected image of the projection device has a linear relationship with the brightne...
