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.
Description
Technical field

Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of method of ordering based on image recognition technology of using for this class Chinese meal shop of chafing dish restaurant is provided, by hand-held intelligent equipment, to ordering, singly take pictures, obtain character image, through image processing and identification technology, the information of ordering is determined, and by hand-held intelligent equipment, will order to pass on a skill from a master to a single disciple and give kitchen and bar desk, thereby reduce waiter's workload, improve the whole work efficiency in dining room; In the whole process of ordering, only need an a papery to order and singly just can complete, reduce papery single use of ordering, avoid the waste of resource.
The object of the invention is to be achieved through the following technical solutions: a kind of method of ordering based on image recognition technology, it comprises the following steps:
Step 1: by hand-held intelligent equipment, ordering of guest singly taken pictures, generating character image;
Step 2: the character image that step 1 is obtained carries out pre-service;
Step 3: the character image to step 2 gained standardizes;
Step 4: extract image information features from the character image standardization;
Step 5: the image information features of extraction is delivered to character recognition engine and identify;
Step 6: according to the character code that is preset in the menu information in hand-held intelligent terminal, recognition result is carried out to automatic Proofreading, obtain recognition result accurately.
The present invention further improves, and described ordering singly comprises the quantity of table number, menu name, vegetable unit price and vegetable.
The present invention further improves, and described character recognition engine comprises Number character recognition engine and alphabetic character identification engine.
The present invention further improves, and described pre-service comprises the location of character image, cuts apart and remove the noise in character image.
The invention has the beneficial effects as follows:
1) by hand-held intelligent equipment, to ordering, singly take pictures, obtain character image, through image processing and identification technology, the information of ordering is determined, and by hand-held intelligent equipment, will order to pass on a skill from a master to a single disciple and send kitchen and bar desk, thereby reduce waiter's workload, improve the whole work efficiency in dining room;
2) in the whole process of ordering, only need an a papery to order and singly just can complete, reduce papery single use of ordering, avoid the waste of resource.
Accompanying drawing explanation
Fig. 1 is character image identification process figure of the present invention;
Fig. 2 is single skeleton diagram of ordering of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of method of ordering based on image recognition technology, it comprises the following steps:
Step 1: by hand-held intelligent equipment, ordering of guest singly taken pictures, generating character image;
Step 2: the character image that step 1 is obtained positions, cuts apart and remove the pre-service such as noise in character image;
According to the location in the sight line character image region of the feature of character image with cut apart, real character image is split; The noise of removing in character image is in order to strengthen the information of character image, is convenient to follow-up word identification.
Step 3: size, position and stroke weight etc. to the character image Chinese word of step 2 gained are standardized;
Step 4: extract image information features from the character image standardization, these character informations mainly comprise the end points of word lines, break and intersection point etc.;
Step 5: the image information features of extraction is delivered to character recognition engine and identify, the image information features extracting according to step 4 carries out separation;
