Description

Technical Field

[0001] The present invention relates to the technical field of test question segmentation and printing, and in particular to a portable test question segmentation and collating device. Background Art

[0002] In the learning process, reviewing and learning wrong questions is an important part of improving students' academic performance. As an auxiliary tool, the wrong question printer can take pictures of the questions on the test paper and print them.

[0003] However, when faced with a large area of ​​questions, the existing method of printing wrong questions is usually to take a picture of the entire question and then print it by zooming in. Although this method can print the entire question in its entirety, the font size after zooming in is often too small, which seriously affects the user's viewing experience.

[0004] For students and other users, too small fonts not only increase the difficulty of reading, but also easily lead to visual fatigue, reducing the efficiency and effect of learning. In view of this, the applicant has specially proposed this application after studying the existing technology. Summary of the invention

[0005] The present invention provides a portable test question segmentation and organization device, aiming to improve at least one of the above-mentioned technical problems.

[0006] In order to solve the above technical problems, the present invention provides a portable test question segmentation and organization device, which includes a content extraction and output device having a content extraction component and a content output component.

[0007] The portable test question segmentation and arranging device further comprises an extraction auxiliary component attached to the content extraction and output device. The extraction auxiliary component is provided with a content segmentation unit. The content segmentation unit is adapted to define a printed medium into at least two parts and to define a content extraction area on the printed medium. The extraction auxiliary component is adapted to position the content extraction and output device at a relative preset position of the content extraction area.

[0008] When the area of ​​the test question to be extracted on the printed medium is larger than the area of ​​the content extraction area, segmentation, extraction and output are performed by the following method:

[0009] The content dividing unit is used to define the print medium into at least two parts.

[0010] The content extraction component is used to extract the printed contents on each part of the printed medium respectively.

[0011] The content output component is used to output each extracted portion of the printed content to a designated medium.

[0012] In an optional embodiment, the content extraction component is provided with a fixed viewing object distance range with clear imaging. The relative preset position is configured to allow the viewing object distance range to cover the content extraction area. Preferably, the content extraction component is configured as a fixed-focus image acquisition module.

[0013] In an optional embodiment, a printed content segmentation and extraction device further includes a medium substrate attached to the designated medium. At least a portion of the medium substrate extends outward from the designated medium along the width direction of the designated medium, so that the width of the medium substrate is greater than the width of the designated medium. Preferably, the medium substrate is 2 to 8 mm wider than the designated medium.

[0014] In an optional embodiment, the extraction auxiliary component further includes a support portion extending obliquely upward from the content segmentation portion, wherein the support portion is provided with a support surface capable of supporting at least a portion of a palm.

[0015] In an optional embodiment, the content segmentation portion is constructed as a "["-shaped structure or a rectangular structure. Preferably, the thickness of the content segmentation portion is not less than 3 mm, and a chamfer is provided on a side close to the content extraction area.

[0016] In an optional embodiment, the content extraction component is located at the center line of the content extraction area. The distance between the content extraction component and the content extraction area is 80 mm to 160 mm. The length of the content extraction area is 210 mm to 160 mm, and the width is 40 mm to 80 mm.

[0017] In an optional embodiment, the content extraction and output device is configured to output only the extracted content with a grayscale lower than a preset value, or is configured to increase the brightness of the extracted content and then output after eliminating grayscale images with a grayscale higher than a preset value.

[0018] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0019] The portable test question segmentation and collating device of the present invention can be used for segmentation, extraction and output of test questions, ensuring that the font size after output can be clearly visible, avoiding the problem of the font being too small to be seen due to over-scaling. In addition, the content printed out each time has the same scale, which can achieve a good splicing effect.

[0020] In addition, by outputting through a designated medium whose width is smaller than that of the medium substrate, white edges can be avoided at the splicing point during splicing, greatly improving the splicing effect. By extracting the test questions through the fixed-focus image acquisition module, clear imaging can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Depend on Figures 1 to 5 As shown, an embodiment of the present invention provides a portable test question segmentation and organization device, which includes a content extraction and output device 1 having a content extraction component 8 and a content output component 3.

[0030] The portable test question segmentation and arranging device further comprises an extraction auxiliary component 2 attached to the content extraction and output device 1. The extraction auxiliary component 2 is provided with a content segmentation unit 5. The content segmentation unit 5 is adapted to define a printed medium into at least two parts, and to define a content extraction area 4 on the printed medium. The extraction auxiliary component 2 is adapted to position the content extraction and output device 1 at a preset position relative to the content extraction area 4.

[0031] The embodiment of the present invention fixes the content extraction output device 1 through the extraction auxiliary component 2, so that the positions of the content extraction output device 1 and the content extraction area 4 will not change, and the distance and position of each photo are the same, which can effectively prevent the photography errors caused by different shooting skills of different photographers, allowing different people to print out wrong questions with the same effect, and well guaranteeing the photography and printing effect of wrong questions.

[0032] On the basis of the above embodiment, in an optional embodiment of the present invention, when the area of ​​the test question to be extracted on the printed medium is larger than the area of ​​the content extraction area 4, segmentation, extraction and output are performed by the following method:

[0033] S1. The content dividing unit 5 is used to define a print medium into at least two parts.

[0034] Specifically, the content segmentation unit 5 can define a content extraction area 4 on the printed medium, thereby defining the printed medium at least into a portion to be extracted and a portion to be extracted. The content segmentation unit 5 can be used to define the content extraction area 4 in batches, thereby dividing the printed medium where the test questions to be extracted are located into multiple parts.

[0035] S2. The content extraction component 8 is used to extract the printed content on each part of the printed medium respectively.

[0036] S3. The content output component 3 is used to output each extracted portion of the printed content to the designated medium 6 respectively.

[0037] Specifically, step S2 and step S3 can be combined into one step, and the content is directly printed out each time it is extracted. It can also be divided into two steps, and after all the content is extracted, it is printed out in sequence. The present invention does not make specific limitations on this.

[0038] When the shooting width is larger than the frame, the content segmentation unit 5 is used to segment the test question into at least two parts, and then extract the content of each part respectively, and then output them respectively on the designated medium 6. These designated media 6 can be assembled into a complete test question. Since the relative position of the content extraction and output device 1 and the content extraction area 4 is fixed, the scaling ratio of the content printed out each time is the same, and the font size of the printed content is the same, and it can be well spliced ​​together without misalignment, which has good practical significance.

[0039] Based on the above embodiment, in an optional embodiment of the present invention, the content extraction component 8 is provided with a fixed viewfinder distance range with clear imaging. The relative preset position is configured to allow the viewfinder distance range to cover the content extraction area 4. Preferably, the content extraction component 8 is configured as a fixed-focus image acquisition module.

[0040] Existing wrong question photo printers use zoom lenses to increase the distance between the wrong question photo printer and the test paper, thereby obtaining a larger viewing range and taking pictures of all the longer questions for printing. However, this is equivalent to shrinking the wrong questions, resulting in the proportion of the wrong questions printed out by taking pictures being too small and the words being unclear.

[0041] A portable test question segmentation and collating device according to an embodiment of the present invention can print test questions with more content in segments, which well guarantees the size of the printed font and avoids the problem of the printed font being too small to affect reading. The content extraction output device 1 is fixed by the extraction auxiliary component 2 provided with the content segmentation part 5, so as to ensure that the zoom ratio of each photo printing is the same, so that a unified effect can be obtained after splicing, further improving the reading experience.

[0042] It should be noted that the fixed viewing object distance range for clear imaging means that the range in which the content extraction component can clearly image is fixed. Specifically, the content extraction component is a camera module with a fixed focal length and a fixed aperture, and the range between a first plane at a first distance and a second plane at a second distance in the shooting direction can be clearly photographed. Among them, the first distance is the minimum object distance for clear imaging (i.e., the minimum focusing distance), and the second distance is the maximum object distance for imaging (i.e., the maximum focusing distance). It can be understood that the range between the first plane and the second plane is the viewing object distance range in the embodiment of the present invention.

[0043] Through the fixed-focus image acquisition module, there is no need to focus when extracting content. Simply placing the extraction auxiliary component 2 on the printed medium can place the printed medium within the object distance range of clear imaging, avoiding the problem of blurry photos caused by focusing errors. At the same time, the content to be extracted can be directly seen through the content extraction area 4, which is clear and intuitive and well guarantees the quality of the output content.

[0044] like Figure 3 As shown, based on the above embodiment, in an optional embodiment of the present invention, a printed content segmentation and extraction device further includes a medium substrate 7 attached to the designated medium 6. At least part of the medium substrate 7 extends outward from the designated medium 6 along the width direction of the designated medium 6, so that the width of the medium substrate 7 is greater than the width of the designated medium 6. Preferably, the medium substrate 7 is 2 to 8 mm wider than the designated medium 6. The designated medium 6 is a thermal printing paper with adhesive backing,

[0045] Understandably, printers are usually unable to print on the edge of the paper, which results in white margins on existing print media. When two sheets of paper are spliced ​​together, the white margins become doubly more obvious, forming a blank line in the middle of the wrong question, affecting the reading experience.

[0046] The printing medium of the embodiment of the present invention sets the width of the designated medium 6 to be narrower than the medium substrate 7, thereby removing the area that the printer cannot print. In the subsequent pasting and splicing steps, the printed contents can be closer to each other to avoid whitening.

[0047] In this embodiment, the width of the medium substrate 7 is 55 to 67 mm, and the width of the printing medium is 50 to 54 mm. Preferably, the width of the medium substrate 7 is 56 mm; the width of the printing medium is 52 mm. In other embodiments, those skilled in the art can set different widths according to actual needs, and the present invention does not specifically limit this.

[0048] like Figure 1 , 2 As shown in , 4 and 5, based on the above embodiments, in an optional embodiment of the present invention, the extraction auxiliary component 2 further includes a support portion 9 extending obliquely upward from the content segmentation portion 5. The support portion 9 is provided with a support surface capable of supporting at least part of the palm. Specifically, when using, part of the palm can be placed on the support surface and the support portion 9 can be held to reduce shaking and avoid the problem of blurring of the extracted content caused by shaking.

[0049] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 1 and Figure 2 As shown, the content dividing portion 5 is constructed as a rectangular structure. Moreover, the thickness of the content dividing portion 5 is not less than 3 mm, and a chamfer is provided on one side close to the content extraction area 4 .

[0050] In this embodiment, the four corners of the content extraction portion are provided with rounded corners. The content extraction portion is provided with a chamfer or rounded corner on one side facing the content extraction portion. By chamfering the content extraction portion, the thickness of the border on one side of the content extraction portion is reduced, and the content in the content extraction portion can be better seen during use. At the same time, the chamfer can reduce the height of the vertical surface of the 4 edges of the content extraction area, avoiding the generation of dark areas on the vertical surface due to the lighting angle when extracting content, and reducing the shadows caused by the side walls. The content segmentation portion 5 can hold down the test paper, effectively preventing the deformation of the photo content caused by the bending deformation of the test paper, thereby taking higher quality images.

[0051] In other embodiments, the content segmentation portion 5 may be a plate-shaped structure made of metal material, thereby further reducing shadows and increasing the field of view. The content segmentation portion 5 may also be constructed as a "["-shaped structure. Marks may be made on two parallel sides, or the end of the side may be used as a mark to indicate the boundary of the content extraction area 4.

[0052] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 4 and Figure 5 As shown, the content extraction component 8 is located at the center line of the content extraction area 4. The distance between the content extraction component 8 and the content extraction area 4 is 80mm to 160mm. The length of the content extraction area 4 is 210mm to 160mm, and the width is 40mm to 80mm. Preferably, the distance between the question extraction component and the bottom of the content extraction part is 110mm to 130mm. The length of the content extraction part is 160mm to 180mm. The width of the content extraction part is 50mm to 70mm.

[0053] In this embodiment, the content extraction component 8 is located on the center line of the viewfinder, and the viewfinder can be placed in the best shooting position of the content extraction component 8 to ensure the shooting quality. In other embodiments, the content extraction component 8 can be set at other positions or angles outside the center line, and then the captured picture is corrected by a correction algorithm, which is not specifically limited in the embodiment of the present invention.

[0054] Existing printers that take photos of wrong questions use zoom lenses to adapt to different shooting distances. When the distance between the camera and the test paper is too large, the printed content will be too small, resulting in the proportion of wrong questions printed out by taking photos being too small and the words being unclear.

[0055] The embodiment of the present invention fixes the content extraction and output device 1 by the extraction auxiliary component 2, so that the relative position of the content extraction and output device 1 and the test paper will not change, and the distance and position of each photo are the same, which can effectively prevent the photography errors caused by different photography skills of different photographers, allowing different people to print out wrong questions with the same effect, and well ensure the photography and printing effect of wrong questions.

[0056] The test content is usually printed on an A4-sized paper area, and margins are set on both sides of the test paper. The inventor has found through a large amount of measurement data that the length of the test questions of all test papers can be covered by a length of 160mm to 180mm. The width of 50mm to 70mm can cover the height of more than 90% of the questions, so that 90% of the questions can be photographed and printed at one time, greatly improving the practicality of the wrong question photography and printing device. The remaining 10% of the questions are photographed and printed in different areas, and then the printed designated media 6 are spliced ​​together for photography and printing, so that all questions can be photographed and printed.

[0057] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 4 and Figure 5 As shown, the content extraction and output device 1 further includes an image defining unit 10; at least part of the image defining unit 10 is disposed between the content extraction component 8 and the content segmentation unit 5 to define the extraction range of the content extraction component 8. Preferably, the extraction range is configured not to exceed the outer boundary of the content segmentation unit 5.

[0058] The image defining portion 10 is configured as a light inlet passage. The cross-sectional shape of at least a portion of the light inlet passage is similar to the contour shape of the image defining portion 10 or the content extraction area 4. In this embodiment, the light inlet passage is configured as a quadrangular pyramid structure, and in other embodiments, the light inlet passage may be configured as other structures such as a quadrangular prism.

[0059] The image delimitation unit 10 defines the extraction range to avoid extracting other unwanted areas, thereby improving the accuracy of the extracted content. This not only reduces the amount of data for the extracted content and greatly reduces the amount of calculation, but also makes the extracted content cleaner and tidier, thereby improving the quality of subsequent output content.

[0060] Based on the above embodiment, in an optional embodiment of the present invention, the content extraction and output device 1 is configured to output only the content with a grayscale lower than a preset value in the extracted content, or to output after eliminating the grayscale image with a grayscale higher than a preset value by increasing the brightness of the extracted content. Preferably, the image defining portion 10 and the content segmentation portion 5 are white.

[0061] Specifically, the embodiment of the present invention removes the light gray content in the picture by removing the highlight part of the image, making the output content cleaner and neater. It also avoids the step of cropping the captured image, which not only saves a lot of computing power and reduces chip costs, but also improves the speed of photo printing, and has a very good practical effect.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
