Image enhancement method and system

The invention discloses an image enhancement method and system, relates to the technical field of machine vision, and solves the technical problems that an existing brightness balancing method is weak in adaptive capacity and poor in image enhancement effect in a complex brightness environment. The method comprises the following steps: S1, preprocessing an obtained original image to obtain a preprocessed image; s2, performing adaptive power transformation processing on the preprocessed image to obtain an initial balanced image; and S3, optimizing the initial equalization image by optimizing the parameters of the adaptive power transformation, and outputting a final equalization image. The method can quickly adapt to different brightness environments, is stable in effect and high in anti-noise capability, and improves the precision of a machine vision technology. 本发明公开了一种图像增强方法及系统，涉及机器视觉技术领域，解决了现有的亮度均衡方法的自适应能力弱，在亮度复杂的环境中图像增强效果差的技术问题。该方法包括：S1、将获取的原始图像预处理，得到预处理图像；S2、将所述预处理图像进行自适应对幂变换处理，得到初始均衡图像；S3、通过优化所述自适应对幂变换的
