Food tracing system

Abstract

The invention discloses a food tracing system. The system comprises at least two intelligent terminals and a traceability information service platform. The intelligent terminal is connected with the traceability information service platform through a network; the intelligent terminal is connected with a color camera. The traceability information service platform comprises an image-based food colorand shape analysis and discrimination module, wherein one intelligent terminal selects an electronic template for tracing food, and the other intelligent terminal selects to trace the color and the shape of the food, and stores characteristic values of the color and the shape acquired based on a video when the food from the third-party detection mechanism is qualified, and the electronic template. The food traceability system solves the problem that an existing consumption-level food traceability system cannot automatically replace human eyes to judge the food quality through the computer vision technology, is convenient to use, prevents package falling and counterfeiting, and solves the problem that consumers with color blindness cannot visually judge the food through the color through the eyes.

Description

technical field [0001] The invention belongs to the field of food safety, and in particular relates to a food traceability system with color and shape auxiliary detection and identification at consumption terminals. Background technique [0002] The traceability information in the current food traceability system includes production, processing, transportation and sales information, and the corresponding food traceability is carried out with the line code or two-dimensional code marked on the food packaging. Due to cost considerations, the code marked on the food packaging It is not a unique code, but the same as the batch code, and the inspection at the factory is only a sampling inspection, so the traceability information often provides sensory indicators of the corresponding external characteristics of the food to allow consumers to further assist in the inspection of the quality and quality of the traced food. In fact, the specific Some sensory indicators are difficult f...

[0002] The traceability information in the current food traceability system includes production, processing, transportation and sales information, and the corresponding food traceability is carried out with the line code or two-dimensional code marked on the food packaging. Due to cost considerations, the code marked on the food packaging It is not a unique code, but the same as the batch code, and the inspection at the factory is only a sampling inspection, so the traceability information often provides sensory indicators of the corresponding external characteristics of the food to allow consumers to further assist in the inspection of the quality and quality of the traced food. In fact, the specific Some sensory indicators are difficult for consumers to grasp or cumbersome to operate. When consumers have sensory defects, they cannot assist in the inspection of the quality and quality of food from the senses. For example, consumers with color-blind eyes cannot pass the test. Eyes intuitively judge food through color
