It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Referring to fig. 1, a flowchart illustrating steps of a scan input method based on a high-speed scanner according to an embodiment of the present invention is shown. The scan input method based on the high-speed scanner provided by the embodiment can be applied to the case of performing scan input based on the high-speed scanner, and specifically comprises the following steps:
and step 110, acquiring bar code image data shot by a high-speed shooting instrument.
In the embodiment of the invention, the bar code image data can represent a bar code image, and the bar code image refers to an image containing bar code content.
In the actual processing, an object containing the barcode can be shot by a high-speed shooting instrument, so that an image containing the barcode content is generated, namely barcode image data is generated. Further, the embodiment of the present invention may further include: and controlling the high-speed shooting instrument to shoot the object containing the bar code so as to shoot through the high-speed shooting instrument to generate corresponding bar code image data. For example, after the label mode containing the bar code is placed below the camera shooting flux of the high-speed camera, the high-speed camera can be controlled by software to shoot, so that bar code image data shot by the high-speed camera can be acquired.
And step 120, performing image processing according to the bar code image data to obtain target image data.
Specifically, after the barcode image data is acquired, the embodiment of the present invention may perform optimization processing on the barcode image data to remove noise and interference information in the image, so as to obtain the target image data. The target image data may represent the optimized barcode image. For example, after the barcode image data is acquired, that is, after the barcode image is acquired, binarization and denoising point operations may be performed on the barcode image, and the interference information may be processed to obtain target image data after optimization processing, so as to achieve the purpose of performing optimization processing on the barcode image data.
And step 130, decoding the target image data to obtain bar code content information.
The barcode content information can be used to characterize the barcode content extracted from the target image data. Specifically, after the target image data is obtained, the embodiment of the present invention may perform decoding by using the open source decoding database based on the target image data to obtain the barcode content information corresponding to the target image data. For example, after the high-speed scanner software optimizes the acquired barcode image data, the open source decoding library zxing.
Further, the decoding of the target image data to obtain the barcode content information may specifically include: calling a decoding library for the target image data; and decoding according to the bar code rule in the decoding library to obtain the bar code content information corresponding to the target image data.
Specifically, after the barcode content information is acquired, the barcode content information may be converted into the simulated keyboard input information, so as to invoke an input method of the operating system to simulate the keyboard input, and input the barcode content information to the designated position where the cursor is located.
Therefore, after the barcode image data shot by the high shooting instrument is obtained, the barcode content information is obtained by performing image processing according to the barcode data and decoding according to the target image data obtained after the image processing, and then the barcode content information can be converted into the analog keyboard input information to be input to the specified position where the cursor is located, so that the trouble that a file output by the high shooting instrument needs to be manually searched and copied and pasted when the content recognized by the high shooting instrument software is input to a text box in the prior art is avoided, that is, the operation of shooting the barcode content to the specified position based on the high shooting instrument is simplified, the problem caused by manually copying and pasting the content recognized by the high shooting instrument software in the prior art is solved, the input efficiency is improved, and the use experience of the high shooting instrument is improved.
In the actual process, the scan input method based on the high-speed scanner provided by the embodiment of the invention can be applied to equipment connected with the high-speed scanner, for example, can be applied to high-speed scanner software, and the high-speed scanner software can be installed in the equipment connected with the high-speed scanner, so that barcode image data shot by the high-speed scanner can be obtained through communication with the high-speed scanner, barcode content carried in the barcode image data can be input to the position of a cursor according to the obtained barcode image data, the scan input function of the high-speed scanner is realized, and the input efficiency is improved. For example, after obtaining the barcode content information, the high-speed scanner software may invoke an input method SendInput () in the operating system dynamic link library user32.dll to simulate a keyboard to input the barcode content information to a position where a mouse cursor is located, that is, convert the barcode content information into simulated keyboard input information to simulate a Human Interface Device (HID) to input the simulated keyboard input information to a position specified by the cursor.
Further, on the basis of the above embodiment, the converting the barcode content information into the analog keyboard input information and inputting the analog keyboard input information to the designated position where the cursor is located in the embodiment of the present invention may specifically include: converting the bar code content information into analog keyboard input information; and calling an input method of an operating system for the simulated keyboard input information. Therefore, the bar code content information can be input to the designated position of the cursor by the input method, for example, the bar code content information is displayed on the text box of the cursor, the bar code scanning input is completed, and the input efficiency is improved. The input method is used for inputting the bar code content information to the designated position where the cursor is located.
Referring to fig. 2, a flowchart illustrating steps of a high-speed scanner-based scan-in method according to an alternative embodiment of the present invention is shown. The scan input method based on the high-speed scanner in the embodiment of the invention is applicable to the scan input situation based on the high-speed scanner, and specifically comprises the following steps:
and step 210, after the communication connection with the high-speed shooting instrument is established, controlling the high-speed shooting instrument to shoot according to a preset video capture equipment protocol.
The preset Video capture device protocol may refer to a preset Video capture device protocol, such as a USB Video Class (UVC) protocol, which is not limited in this embodiment.
And step 220, acquiring the bar code image data shot by the high-speed shooting instrument.
Specifically, the embodiment of the invention can establish communication connection with the high-speed camera in advance, and can control the high-speed camera to shoot according to a preset video capture device protocol based on the communication connection, so that barcode image data shot by the high-speed camera can be acquired. .
As an example of the present invention, the high-speed scanner hardware may be connected to a computer through a Universal Serial Bus (USB), and a barcode to be photographed may be placed under a camera of the high-speed scanner, for example, a tag containing the barcode may be placed under the camera of the high-speed scanner, so that the high-speed scanner software installed on the computer side may obtain a barcode image photographed by the high-speed scanner device by communicating with the high-speed scanner using a standard UVC protocol, that is, barcode image data. Specifically, after the label containing the barcode is placed under the camera of the high-speed scanner, the high-speed scanner software installed on the computer side communicates with the high-speed scanner using the standard UVC protocol, so that the high-speed scanner can be controlled to shoot, barcode image data generated by shooting by the high-speed scanner can be acquired, that is, a picture containing the barcode is acquired, and then step 230 is executed.
And step 230, performing image processing according to the barcode image data to obtain target image data.
Further, the embodiment of the present invention performs image processing according to the barcode image data to obtain target image data, and specifically includes the following sub-steps:
substep 2301, performing graying operation based on the barcode image data to obtain grayscale image data.
A substep 2302 of performing noise reduction processing according to the gray-scale image data to obtain noise-reduced picture data;
and a substep 2303 of performing image binarization processing based on the noise reduction picture data to obtain target image data.
Specifically, in the embodiment of the present invention, after the high-speed camera acquires the barcode image data, the acquired barcode image may be grayed based on the barcode image data to obtain grayscale image data. For example, the brightness of three color components, Red (R), Green (G), and Blue (B), in the acquired color image containing the barcode may be simply averaged, and the obtained value may be output as a gray scale value to obtain a gray scale image, i.e., gray scale image data.
The image may then be denoised based on the grayscale map data, such as by using a median filtering algorithm to denoise the image based on the grayscale map data to eliminate noise in the image, resulting in denoised picture data. The noise-reduced picture data may represent noise reduction after noise reduction, i.e. represent a picture after image noise points are eliminated. Of course, in the embodiment of the present invention, noise reduction may be performed by using other noise reduction methods besides using a median filtering algorithm, and the implementation of the present invention is not particularly limited thereto.
Further, after the noise reduction image data is obtained, a binarization threshold value may be obtained by using a maximum inter-class difference method (Ostu) for the image based on the noise reduction image data, and the image is binarized by using the threshold value, for example, the gray value of a point on the image is set to 0 or 255, that is, the whole image exhibits an obvious black-and-white effect, wherein the condition for changing the gray value is that the gray value of a pixel of which the gray value is greater than or equal to the threshold value is set to 255, otherwise, the gray value of the pixel is 0, so as to achieve the purpose of optimizing the image, and obtain the target image data after the image is optimized.
And step 250, decoding according to the bar code rule in the decoding library to obtain the bar code content information corresponding to the target image data.
Specifically, after the target image data is obtained, the embodiment of the present invention may invoke a decoding library to decode the target image data according to a barcode rule in the decoding library, so as to obtain barcode content information in the target image data. For example, after the image is optimized, the high-speed scanner software may call an open source decoding library zxing.net for the target image data after the optimization, decode the target image data according to a barcode rule by using the open source decoding library zxing.net, obtain the content in the barcode, that is, obtain the barcode content information, and then execute step 260.
Step 260, converting the bar code content information into analog keyboard input information.
Specifically, after the barcode content information is acquired, the acquired barcode content information can be converted into the input information of the simulated keyboard, so that the input method of the operating system is called to simulate the keyboard to be input to the position where the cursor is located, and the purpose of inputting the barcode content information to the specified position is achieved. The input method of the operating system is used for inputting the bar code content information to the designated position where the cursor is located.
As an example of the present invention, the obtained barcode content may be used to call a SendInput method of the Windows system user32.dll function library to simulate a keyboard input to a position where a mouse cursor is located. Specifically, after the acquired bar code content information is converted into the input information of the simulation keyboard, a SendInput method of a Windows system user32.dll function library is called based on the input information of the simulation keyboard, so that the bar code content is input into a text box where a mouse cursor is located through the SendInput method, the purpose of inputting the bar code content scanned and shot by a high-speed scanner into the text box is achieved, the trouble of searching for a high-speed scanner output file and copying and pasting by a user is avoided, the operation of the user is simplified, and the input efficiency is improved.
To sum up, after establishing communication connection with the high-speed shooting instrument, the embodiment of the invention controls the high-speed shooting instrument to shoot according to the protocol of the video capture device, obtains the bar code image data shot by the high-speed shooting instrument, can process the image according to the bar code data to obtain the target image data, then decodes according to the target image data, converts the decoded bar code content information into the analog keyboard input information, and inputs the analog keyboard input information to the designated position where the cursor is positioned by calling the input method of the operating system, thereby solving the problem caused by the fact that the high-speed shooting instrument software directly writes the identified content into the file output by the high-speed shooting instrument in the prior art, avoiding the trouble that the file output by the high-speed shooting instrument needs to be manually searched and manually copied and pasted in the prior art, namely simplifying the complex operation that the traditional high-speed shooting instrument software needs to manually open the file and manually copy and paste, the software use experience is improved, and the scanning input efficiency based on the height instrument is improved.
