System for testing clarity of images on food surfaces based on images

The utility model relates to a system for testing clarity of images on food surfaces based on images, which comprises an image collecting device (1) for testing images on surfaces of tested food (2), a top light source (3), a bottom light source (4) and an image processing and analyzing device (5), wherein the top light source (3) and the bottom light source (4) are arranged on the top and on the bottom of the food (2) respectively, the image collecting device (1) is arranged above the tested food (2), and a signal output end of the image collecting device (1) is connected with a signal input end of the image processing and analyzing device (5). The system is capable of forming a unified standard for judging clarity of the surface images of the same food, guaranteeing testing quality, has high efficiency in testing, low cost, and is practical and convenient to use.
