The design effect of customized product packaging is poor due to the influence of light ,shadow and color difference. The visual image processing method of customized product packaging based on line structured light ima- ging technology. The line structured light imaging technology is used to build a visual imaging model for customized product packaging design ,analyze the difference degree of packaging image features with the change of light stripe ,and combine the depth and brightness analysis method of color space to adjust the light stability of 3D printing image in HSV color space by using the line structured light adjustment method. Through the analysis of the significance value of super pixel and the decomposition of adjacent pixel features ,Realize the integration of visual depth and brightness of customized product packaging. The experimental results show that the proposed method has better shadow and color suppression ability ,better visual image information expression ability ,the minimum mean square error is 0. 109 ,the output peak signal-to-noise ratio is 46 dB ,the peak signal-to-noise ratio is higher ,the maximum information entropy is 0. 93 ,and the SSIM value is larger when the iteration number is 10. And it ’s close to 1.
