The embodiment of the invention discloses an image correction method and device of a multi-light-source system, a terminal and a storage medium, which are applied to a detection system, and the detection system comprises at least one detection station, a camera device corresponding to the detection station and a plurality of correspondingly arranged group light sources; the method comprises the following steps: acquiring a training image corresponding to the detection station under each group of light sources through the camera device; calculating a correction coefficient corresponding to eachgroup of light sources based on the training image and storing the correction coefficient; and collecting a target image corresponding to the to-be-detected product through the camera device, and correcting the target image according to the correction coefficient. In addition, the embodiment of the invention further discloses an image correction device of the multi-light-source system, a terminaland a computer readable medium. By adopting the invention, the group light source correction operation of the multi-light-source system can be realized, and a good image required by detection can beobtained under the condition of multiple light sources.

The invention discloses a rapid multi-scale super-pixel segmentation method for a synthetic aperture radar image. The method comprises the following steps: measuring the final similarity of two pixelsin combination with backscattering gray similarity, edge information similarity and homogeneity similarity; performing graph structure representation on the SAR image; constructing a minimum spanningtree for the SAR image; sAR image fast multi-scale super-pixel segmentation is achieved based on the minimum spanning tree, a super-pixel segmentation boundary is obtained based on a segmentation result, and an SAR image segmentation result is generated. According to the invention, any number of superpixels with a tree structure can be generated immediately, so that superpixel results of different levels can be segmented. According to the multi-scale super-pixel segmentation method, image boundaries can be well kept, the good image local detail keeping capacity is achieved, the segmentation result of any scale can be generated for the SAR image in real time, target information of different sizes can be easily obtained, and the execution efficiency is remarkably improved.
