As shown in fig. 2 and fig. 3, there is also provided a method for accurately capturing local information in a picture, where the method includes:

step S11, forming a selection frame around the information to be captured in the picture by the laser 74;

step S12, shooting the picture with the selection frame, forming the picture and storing the picture in a shooting tool;

step S13, recognizing the picture in the shooting tool, and cutting the picture along the selection frame after recognizing the selection frame;

and step 14, carrying out binarization processing on the cut picture.

Specifically, when the error is to be collected, a selection frame is formed around the error by the laser 74, the selection frame may be rectangular or square, after the selection is completed, the selection frame is photographed by the photographing tool, the photographed photo identifies the selection frame, the redundant portion outside the selection frame is cut, the content in the selection frame, that is, the error information, is finally obtained, and the required information can be obtained by binarizing the error information.

In the binarization processing of the image, the gray-scale value of a point on the image is set to 0 or 255, that is, the whole image is obviously black and white. That is, a gray scale image with 256 brightness levels is selected by a proper threshold value to obtain a binary image which can still reflect the whole and local features of the image. In digital image processing, binary images are very important, and particularly in practical image processing, many systems are configured by binary image processing, and in order to perform processing and analysis of binary images, a grayscale image is first binarized to obtain a binarized image, which is advantageous in that when an image is further processed, the collective property of the image is only related to the positions of points with pixel values of 0 or 255, and the multi-level values of the pixels are not related, so that the processing is simplified, and the processing and compression amount of data is small. In order to obtain an ideal binary image, a non-overlapping region is generally defined by closed and connected boundaries. All pixels with the gray levels larger than or equal to the threshold are judged to belong to the specific object, the gray level of the pixels is 255 for representation, otherwise the pixels are excluded from the object area, the gray level is 0, and the pixels represent the background or the exceptional object area.

If a particular object has a uniform gray level inside it and is in a uniform background with gray levels of other levels, a comparable segmentation effect can be obtained using thresholding. If the difference between the object and the background is not represented in gray scale values (e.g., different textures), the difference feature can be converted into a gray scale difference, and then the image can be segmented using a threshold selection technique. The threshold value is dynamically adjusted to realize the binarization of the image, and the specific result of the image segmentation can be dynamically observed.

In some embodiments, the step S14 is followed by:

and step S15, matching the information after the binarization processing in the library, and determining the information as the information needing to be captured after finding the best matched information.

Specifically, the problem base is connected, the information after binarization processing is compared with the problems in the problem base to obtain the original problems of wrong problems, the original problems are directly printed, and the problem that the information after binarization processing is typeset again is solved.

In some embodiments, the size of the selection box is changed by controlling the distance between the capture tool and the picture.

Specifically, when the selection of the selection frame is wrong, some questions are long, some questions are short, and the size of the selection frame can be realized by adjusting the distance between the shooting tool and the picture, so that a proper cutting interval is selected, and selection of various questions is facilitated.

In some embodiments, the step S11 is followed by:

and step S16, reducing the size of the selection box through an auxiliary tool.

In some embodiments, the auxiliary tool is a ruler or a finger.

Specifically, although the size of the selection frame emitted by the laser 74 can be scaled up or down by adjusting the distance between the shooting tool and the picture, it is impossible to frame the wrong question at any time, and sometimes the length is the same as the wrong question, but the width is larger or smaller.

When a selection frame exists in a shot picture and an auxiliary tool also exists, at the moment, the picture is cut for the first time along the selection frame and then cut for the second time along the auxiliary tool, so that the cut picture is just wrong.

In some embodiments, the selection box is rectangular.

In some embodiments, the laser 74 is disposed on the camera tool.

The utility model also provides a system that local information is accurate snatchs in picture, the system includes:

the shooting tool is further provided with a laser 74, the laser 74 is used for forming a selection frame around information needing to be captured in a picture, and the shooting tool is used for shooting a picture of the picture;

a selection box identification module 20 for identification of a selection box;

a cropping module 30 for cropping the picture along the selection box; and

and a binarization processing module 40, which is used for processing the cut picture information.

In some embodiments, the system further comprises:

a comparison module 50 for comparing the identified picture information with information in the library.

In some embodiments, the system further comprises:

an auxiliary tool identification module 60 for identifying an auxiliary tool.
