Description

Online shopping support system based on indoor color correction and consistency The present invention relates to a technology that supports the selection and purchase of interior products by accurately analyzing and correcting interior colors, wallpaper colors, etc., based on images captured in an indoor environment. In particular, it relates to a color analysis and correction system capable of correcting color distortion caused by lighting conditions and camera performance, and recommending products that harmonize with the indoor environment. In addition, the present invention belongs to the field of technology that improves customer convenience and purchasing accuracy in accordance with the increasing trends of DIY interior design and online purchasing. With the recent increase in single-person households and growing interest in personalized living spaces, DIY interior design—where customers decorate their own living environments—is establishing itself as a trend. Consequently, the purchasing method for interior products is rapidly shifting from offline to online, and the proportion of customers conveniently comparing and purchasing various products through online shopping malls continues to rise. However, when purchasing products online, the color or design may not match the customer's indoor environment or may differ from expectations, acting as a major factor that lowers purchase satisfaction. In particular, indoor environmental colors and wallpaper colors play a crucial role in the selection of interior products. While consumers desire to choose products with colors that harmonize with their home interiors, the current online shopping environment makes it difficult to accurately match product images with the customer's home environment. This problem is exacerbated when colors appear distorted due to differences in shooting environments (e.g., lighting conditions) and camera performance. It is common for colors to appear brighter than they actually are under bright lighting and darker under dim lighting, making it difficult for customers to judge the accurate color. Therefore, to accurately analyze the actual colors of the indoor environment, color correction technology capable of minimizing the influence of cameras and lighting is required. Furthermore, to enable customers to easily select products using images of their home interiors, technology is needed to analyze and correct the colors of captured images to recommend products that harmonize with the customer's indoor environment. Existing color analysis technologies have primarily relied on simply comparing color data extracted from images; however, this method has limitations, as its accuracy deteriorates depending on lighting conditions or camera characteristics. Consequently, there is a growing need for the development of technology capable of correcting colors distorted by lighting conditions and camera performance, and recommending products suitable for indoor environments based on this correction. This invention proposes a color correction and analysis system to address these issues, aiming to provide consumers with a more convenient and reliable online interior purchasing environment.
