Embodiment 1

[0060] like figure 1 shown, figure 1 A question answering method for a photographic clicker provided by an embodiment of the present invention is shown. The execution subject of the method in this embodiment may be a photographing structure. Specifically, the answering method in this embodiment may include the following steps:

[0061] S1: After receiving the photographing request triggered by the user for photographing the subjective question, the photographing clicker generates a photographing frame according to the preset paper size.

[0062] For example, the above step S1 may specifically include:

[0063] The photographing clicker receives a photographing request triggered by the user for photographing the subjective question.

[0064] Displays at least one paper size to be selected.

[0065] After receiving the user's selection instruction, the photo frame is generated according to the paper size corresponding to the selection instruction as the preset paper size.

...

Embodiment 2

[0088] like figure 1 and figure 2 As shown, in step S1 in Embodiment 1, the photographing frame includes a first frame 10 and a second frame 11, and the first frame 10 and the second frame 11 are closed frames with overlapping geometric centers, the same shape and different sizes. . And in step S3 , the area information of the photographing frame is the area between the first frame 10 and the second frame 11 .

[0089] In this embodiment, the first frame 10 and the second frame 11 are set, and when the border 20 of the image of the paper to be photographed is located between the first frame 10 and the second frame 11, the image quality check is performed to obtain the image quality check. Kernel value F(s,a). By adjusting the clicker, the user will make the border 20 of the image in the area information of the photo frame, so that the quality of the image captured by the clicker can be guaranteed, and only needs to fine-tune the position of the border 20 in the area inform...

Embodiment 3

[0091] On the other hand, the present invention also provides a photographing method, comprising:

[0092] P1: After receiving a photographing request triggered by the user for photographing the paper to be photographed, a photographing frame is generated according to preset photographing conditions. The preset photographing condition refers to a preset paper size, and the preset paper size corresponds to the size of the paper to be photographed.

[0093] P2: According to the image of the paper to be photographed displayed in the photographing frame, the boundary 20 of the image is identified.

[0094] P3: According to the boundary 20 and the photographing frame, determine whether the boundary 20 is completely within the area information of the photographing frame.

[0095] P4: When the boundary 20 is completely within the area information of the photographing frame, obtain the image calibration value F(s, a) according to the boundary 20, the image within the boundary 20, and...

Abstract

The invention relates to an answering method and a photographing method of a photographing answering device, the photographing answering device and a system, and the answering method comprises the steps: S1, generating a photographing frame according to a preset paper size after the photographing answering device receives a photographing request which is triggered by a user and is used for photographing subjective questions; S2, according to the image of the to-be-photographed paper displayed in the photographing frame, identifying the boundary of the image; S3, according to the boundary and the photographing frame, determining whether the boundary is in the area information of the photographing frame; S4, when the boundary is located in the area information of the photographing frame, obtaining an image check value F (s, a) according to the boundary, the image in the boundary and the photographing frame, wherein the image check value F(s, a) is associated with the number of pixel points of the image in the boundary and an included angle of adjacent edges in the boundary; S5, according to the image check value F(s, a), judging whether a shooting condition is satisfied, and when the shooting condition is satisfied, displaying a shooting identifier. The shot picture is clear after the shooting condition is met, so the quality of the acquired image can meet the requirement.

Description

technical field [0001] The invention relates to the field of teaching, in particular to a question answering method of a photographic answering machine, a photographing method, a photographic questioning machine and a system. Background technique [0002] In the classroom teaching process, the functions of the clicker tend to be more diverse. As a convenient terminal product, the clicker can not only effectively mobilize students' learning enthusiasm, but also help teachers keep abreast of students' mastery of knowledge points , to clear the blind spots in teaching, is to realize the information-based classroom interaction between teachers and students in the true sense, but the current clicker is only for objective questions such as selection and judgment, which can be convenient for answering and reviewing, but for quizzes or fill-in-the-blanks, etc. Subjective questions can only be manually collected paper test papers and manually reviewed test papers. In order to realiz...
