活雞網(wǎng)絡(luò)銷售關(guān)鍵技術(shù)研究
[Abstract]:With the rapid development of economy and the improvement of people's living standard, chicken has become a common dish on people's table. But since the outbreak of the bird flu virus, how to safely buy live chicken has become a top priority for local governments. At present, many local governments are vigorously implementing the "targeted slaughter, killing white listing" system, through "centralized slaughtering, cold chain transport, fresh market" and other measures to avoid the spread of avian influenza virus. But the system has the following shortcomings: on the one hand, after slaughter, "white striped birds" taste poor, freezing costs increased; on the other hand, consumers have a variety of concerns about the safety and health of "white striped birds". In this paper, a network selling method of live chicken is introduced, and the key technology is solved. This method not only guarantees the freshness of the live chicken, reduces the storage cost, but also realizes the WYSIWYSIWY income of the live chicken sale. The main contents of this paper are as follows: (1) preprocessing of chicken crowns image, including image segmentation, image enhancement and binarization. Ostu threshold segmentation method is used to segment the image, histogram equalization method is used to get the enhanced image. Finally, the binary image of the chicken crown image is obtained. (2) the similarity of the chicken crown image is calculated. Emphasis is placed on the use of contour features to calculate the similarity of chicken crowns. By extracting the contour line, the two-dimensional contour information is stored in the one-dimensional sequence to calculate the similarity. (3) A live chicken sales platform is designed. The database of live chicken sale platform and the design of Web page are introduced in detail. The database contains four data tables: live chicken information table, buyer information table, supplier information table and history record. The Web page includes user registration page, login page, live chicken purchase page, similarity comparison page, etc. History order page and buyer information page. (4) testing of live chicken selling platform. The registration page, login page, live chicken page, similarity comparison page, historical order page and buyer information page of the platform are tested to ensure the stable operation of the platform.
