Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic structural diagram of a level determination and entry method according to an embodiment of the present invention.
Detailed Description
Example 1
A grade judging and inputting system is composed of a camera, an identification module, a decoding module, a storage module, a processing module and a network module.
The camera, the identification module, the decoding module, the storage module, the processing module and the network module are sequentially connected.
The working process of the grade judgment and entry system is as follows:
the method comprises the steps of firstly obtaining a shooting area image through a camera, and then identifying a set symbol (such as a two-dimensional code) in the image through an identification module. And then decoding and acquiring the two-dimensional code information through a decoding module. The two-dimensional code information includes a two-dimensional code position, a two-dimensional code moving direction, two-dimensional code appearance time, whether the two-dimensional code disappears in a shooting area, and the like. The processing module processes the combination of different information to judge the grade of the current operation, the storage module stores all data, and finally the processing module processes the data according to the service requirement and uploads the data to the server side (figure 1) through the network module.
The set symbol in the image can be a bar code, a book cover or a self-defined symbol besides a two-dimensional code.
Example 2
The embodiment illustrates how to determine and record student achievements by using the two-dimensional code through the grade determination and recording system, and the specific steps are as follows:
(1) the camera captures an image of a shooting area;
(2) the identification module identifies whether the two-dimensional code exists in the current image; if the two-dimensional code exists, the decoding module decodes the two-dimensional code and checks whether the returned data conforms to a preset information rule, wherein the information rule comprises identification information representing students, such as class, name and sex of the students; the storage module records the information returned by the current decoding module and the position returned by the identification module; if the two-dimensional code does not exist or the decoded data does not accord with the preset information rule, returning to the step (1);
(3) the processing module judges the performance of the job as a certain performance grade, such as excellent, good and qualified according to the position of the two-dimensional code or the time of the appearance of the set symbol or the moving direction or the moving speed, and then the storage module stores the decoding information and the judged performance grade;
(4) uploading the decoding information and the judged achievement level to a server by the network module; the uploading mode can be one by one or batch;
(5) and (4) returning to the step (1).
Specifically, in step (3), the results are determined in 4 ways:
(1) different determination areas are set to represent different achievement levels: dividing a shooting area of a camera into a plurality of judgment areas, wherein each judgment area represents different achievement levels; the work with the two-dimensional code is placed in a certain judgment area, and the camera judges the work as the achievement level represented by the judgment area by identifying the two-dimensional code placed in the judgment area.
(2) Judging the achievement level by judging the disappearance of the two-dimensional code in the area: specifically, the operation of the two-dimensional code placed in a certain judgment area is recognized by a camera, then the two-dimensional code on the operation disappears in a shielding or other mode within a set time, and the two-dimensional code information recorded before the storage module appears, and then the operation achievement grade is recorded as a certain set grade.
(3) The grade is determined by determining the moving speed of the set symbol in the area: specifically, the operation with the two-dimensional code in a certain judgment area is identified by a camera, and then the operation with the two-dimensional code is moved to an adjacent judgment area within a set time, and then the operation achievement grade is recorded as a certain set grade.
(4) The rank is determined by determining the direction of movement of the set symbols within the region: specifically, the operation of the two-dimensional code placed in a certain judgment area is recognized by a camera, and then the operation with the two-dimensional code is moved to an adjacent judgment area in a set direction, and then the operation achievement level is recorded as a certain set level.
The 4 determination methods described above may be used alone, or two or more types may be used in combination. The method comprises the following specific steps:
1) and (4) separately using different judging areas for judging and recording the achievement. For example, 3 judging areas represent 3 achievement levels, wherein each area represents the excellence, the goodness and the badness of the achievement of the student respectively. The camera can judge the result grade (excellent or good or poor) represented by the job in a certain judgment area of the 3 judgment areas by identifying the two-dimensional code carried by the job, and the judged result is recorded into the system at the same time of judging the result.
2) And (4) judging and recording the scores by combining different judging areas and different disappearing modes. For example, the lower surface of the camera is divided into 2 left and right judgment areas, which respectively represent 2 achievement levels (such as excellent and good), and the level of the work achievement is judged according to the disappearance or moving direction of the two-dimensional code in any one of the 2 judgment areas. The student homework is placed in one of the 2 judging areas, the camera recognizes the two-dimensional code carried on the homework placed in the judging area, then the two-dimensional code on the homework is shielded within a set time, or the homework is moved to the adjacent judging area, the two-dimensional code on the homework disappears from the camera, the achievement grade of the homework can be judged to be poor, and the judged homework achievements are uploaded one by one while the achievement is judged. Thus, the judgment and the entry of 3 achievement levels can be realized only by setting 2 judgment areas.
In addition, different judgment areas and moving speeds can be combined for use, and more grades of judgment and entry can be realized.
Example 3
The embodiment illustrates how to determine and record the product quality grade by using the two-dimensional code through the grade determination and recording system.
(1) The camera captures an image of a product quality inspection certificate in a shooting area;
(2) the identification module identifies whether the two-dimensional code exists in the image of the current product quality inspection certificate; if the two-dimensional code exists, the decoding module decodes the two-dimensional code and checks whether the returned data conforms to a preset information rule, wherein the information rule comprises identification information representing a product, such as the name, the model, the specification and the like of the product; the storage module records the information returned by the current decoding module and the position returned by the identification module; otherwise, returning to the step (1);
(3) the processing module judges the product quality inspection certificate to be a certain quality grade, such as first-class, second-class, third-class and other external products, according to the position of the two-dimensional code or the time or the moving direction or the moving speed of the set symbol, and then the storage module stores the decoding information and the judged product quality grade;
(4) uploading, by the network module, the decoded information and the determined product quality level to a server; the uploading mode can be one by one or batch;
(5) and (4) returning to the step (1).
Specifically, in step (3), the determination method of the product quality grade includes the following 4 methods:
(1) different decision zones are set to represent different product quality grades: dividing a shooting area of a camera into a plurality of judgment areas, wherein each judgment area represents different product quality grades; and the camera judges that the product quality certificate is the grade represented by the judgment area by identifying the two-dimensional code carried by the product quality certificate placed in the judgment area.
(2) Judging the achievement level by judging the disappearance of the two-dimensional code in the area: specifically, a camera identifies a product quality inspection certificate of a two-dimensional code in a certain judgment area, and then the two-dimensional code on the product quality inspection certificate disappears in a shielding or other mode within a set time and appears in two-dimensional code information recorded before a storage module, and then the grade of the product quality inspection certificate is recorded as a certain set grade.
(3) Judging the grade by judging the moving speed of the two-dimensional code in the area: specifically, a camera identifies a product quality inspection certificate with a two-dimensional code in a certain judgment area, and then the product quality inspection certificate with the two-dimensional code is moved to an adjacent judgment area within a set time, and then the grade of the product quality inspection certificate is recorded as a set grade.
(4) Judging the grade by judging the moving direction of the two-dimensional code in the area: specifically, a camera identifies a product quality inspection certificate with a two-dimensional code in a certain judgment area, and then the product quality inspection certificate with the two-dimensional code is moved to an adjacent judgment area in a set direction, and then the grade of the product quality inspection certificate is recorded as a set grade.
The above-mentioned 4 determination methods may be used alone or in combination of two or more methods, as in example 2.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
