Abstract

The invention discloses a food ordering method based on an image identifying technology. The method includes the following steps: using a waiter handheld intelligent device to take a picture of a meal list of a customer so as to generate a character image; preprocessing the character image and normalizing the character image; extracting character feature information from the normalized character image; sending the extracted character feature information to a character recognition engine for recognition; and performing automatic proofreading on the recognition result according to character codes of menu information preset in the handheld intelligent terminal so that an accurate recognition result is obtained. In the food ordering method based on the image identification technology, the picture of the meal list is taken so that the character image is obtained and then the food ordering information is determined through an image processing and identification technology and then the meal list is transferred to a kitchen and a counter through the handheld intelligent device so that workload of waiters is reduced and the whole work efficiency of a dining hall is improved; and the whole food ordering process can be completed through only one paper meal-list sheet so that use of paper meal-list sheets is reduced and waste of resources is prevented.
