Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

The method for identifying object information provided in this application can be applied to the application environment as shown in FIG. 1. The scanning terminal 101 obtains the corresponding first identification information by scanning the color code, and uploads the first identification information to the processing unit 102. The processing unit 102 determines the position of the second color code when the first identification information meets a preset condition, and obtains The second identification information further determines the information identification result of the object. The scanning terminal 101 may be various terminals with scanning functions, including but not limited to smart phones and scanners. The processing unit 102 may be a server, a personal computer, a notebook computer, a smart phone, a tablet computer, a POS machine, or a portable wearable device. In addition, the processing unit 102 may upload the acquired and processed data to a server for data sharing with other devices.

The embodiments of the present invention provide a method, a device, a computer device, and a storage medium for identifying object information. In the following, the method is applied to the processing unit 102 in FIG. 1 as an example for detailed description.

In an embodiment, as shown in FIG. 2, a method for identifying object information is provided, which includes the following steps:

S201: Acquire first identification information of the first color code of the object.

Among them, the object refers to the thing that can display or display the color code. It can refer to items, commodities, people, pictures displayed on the screen, etc. The first color code can be displayed on the object or pasted on the object.

The first color code refers to a bar code expressed in a color format, which can be a color one-dimensional code, a color two-dimensional code, or other formats. At the same time, the first color code can include one barcode (a vertical line or a horizontal line), or two or more barcodes.

The first identification information refers to the color (which can be converted into RGB value, etc.), the quantity, the form, and other information contained in the color code obtained after the first color code is recognized.

Further, it may be the data obtained after quantizing the initial data obtained by the color code to facilitate subsequent information processing.

In addition, obtaining the first identification information of the first color code can be achieved by scanning the first color code by a terminal with a scanning function, or can be achieved in other ways. These scanning terminals may be provided with a camera (so it can be considered that the first color code is scanned by the camera). Among them, the camera (CAMERA or WEBCAM), also known as computer camera, computer eye, electronic eye, etc., is a video input device, and is now widely used in many fields such as video conferencing, telemedicine, and real-time monitoring.

S202: When the first identification information meets a preset condition, determine the position of the second color code of the object; the position is determined according to the first color code.

In this step, when the first identification information meets the preset condition, the location of the second color code of the object is determined according to the positioning function of the first color code.

Wherein, the second color code is determined when the first identification information meets the preset condition, and the encryption function of the first color code is used. In this case, the first color code may be called a security code. The position of the second color code is determined according to the first color code, and the positioning function of the first color code is used. At this time, the first color code can be called a positioning code.

The encryption of the first color code can improve the information security and anti-counterfeiting capabilities of the object. If the first identification information captured by the scanning device does not meet the preset condition, the first color code can be regarded as an invalid code, and the next step of obtaining the second identification information will not be performed. Such a processing method can greatly improve the information security of the object. Of course, the developer can choose whether to enable the security code function, and whether to open the security code after use. That is, if the developer chooses not to enable the security code, he can directly determine the corresponding information identification result based on the second identification information when the second identification information is obtained without the judgment of the first identification information.

In addition, judging whether the first identification information meets the preset conditions can be judging whether the first identification information meets the conditions in terms of size, quantity, etc., or judging whether the first identification information matches a preset threshold, and of course it can also be The other way.

The first color code and the second color code can be independent of each other in position or can contain each other.

In addition, the first color code and the second color code can be expressed in multiple forms, for example, they can be expressed directly by numbers, by words, or by graphics. Among them, the graphical representation can be achieved by various graphics, for example: it can be represented by a rectangular frame or can be represented by a circular frame.

Further, the realization process of determining the position of the second color code may be: the first identification information of the first color code may contain the position information of the second color code, so the second color code can be determined according to the first identification information position. It may also be that there is a certain relationship between the positions of the first color code and the second color code, and the position of the second color code can be determined according to the position of the first color code. In addition, the position determined according to the first color code may be the precise position of the second color code, or may be the approximate position.

S203. Acquire second identification information of the second color code in the position, and determine an information identification result of the object according to the second identification information.

Among them, the information recognition result of the object may be item information (for example, information such as computer size, model, and date of manufacture), product price, product model and other information. There may be a corresponding relationship between the information recognition result and the second identification information, which ensures that the corresponding information recognition result can be determined based on the second identification information and the corresponding relationship.

In addition, acquiring the second identification information of the second color code can also be achieved by scanning the second color code by a terminal with a scanning function, like acquiring the first identification information. Similarly, it can be achieved in other ways.

At present, when identifying information codes such as one-dimensional codes and two-dimensional codes, it is necessary to scan the scanning head of the terminal close to the information code to capture the information. For some industries or under special circumstances, product information cannot be obtained quickly. The first color code in this embodiment has both an encryption function and a positioning function. The second identification information of the second color code can be determined more accurately and easily, and more accurate object recognition results can be obtained quickly, so that information can be recognized. The fault tolerance rate is greatly reduced.

In an embodiment, before the step of determining the position of the second color code of the object when the first identification information meets a preset condition, the method further includes: acquiring a predetermined first color of the object Code information; when the first identification information matches the first color code information, it is determined that the first identification information meets a preset condition.

Among them, the first color code information may be artificially specified or calculated according to a certain algorithm.

Before identifying the object information, the corresponding first color code information (as verification information) can be set for the object. If the identified first identification information matches the predetermined first color code information, it can be considered The first identification information meets the preset condition. In this embodiment, in this way, it can be accurately and quickly determined whether the first identification information satisfies the condition, and the information identification efficiency of the object can be improved.

In an embodiment, the first color code can be represented by four color blocks ABCD (of course, the color blocks contained in the first color code can be more or less, and can also be represented in other ways). You can assign different numerical numbers to the RGB values of these color blocks. When determining the RGB value of the first color code color block, determine its corresponding numerical number, and then determine the first identification information. Table 1 below shows the correspondence between different RGB values and numerical numbers. In order to facilitate the color capture by the camera, the maximum value 255 and the minimum value 0 of the RGB function can be used to define the color. For example, eight colors can be used to correspond to the octal number 0-7, as shown in Table 1 (it can also be set to Binary, decimal, hexadecimal, etc.). The colors defined by the maximum value and the minimum value are all pure colors and have a high degree of recognition, which can effectively improve the accuracy of the identification information acquisition, thereby improving the accuracy of the object's information recognition result. Of course, the RGB values corresponding to these numerical numbers can also be other values.

Among them, the RGB color mode is a color standard in the industry. A variety of colors are obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them with each other. colour. This color standard includes almost all colors that human vision can perceive, and is one of the most widely used color systems. When the RGB function executes successfully, it returns the color determined by the specified component, which is represented by a long integer. The requirements of RGB three channels are as follows:

blueblue	必要参数；Integer类型；数值范围：0～255；表示颜色的蓝色成份Necessary parameter; Integer type; value range: 0～255; represents the blue component of the color

Table 2 Requirements for RGB three channels

In an embodiment, both the first color code information and the first color code information may be information composed of numerical numbers, and the numerical numbers corresponding to the first color code information may be pre-stored in the processing unit. If the numerical number in the first identification information corresponds to the numerical number in the first color code information, it can be considered that the two match, and it is determined that the first identification information satisfies the preset condition; if the numerical number in the first identification information If it does not correspond to the numerical number in the first color code information, it can be determined that the first identification information does not meet the preset condition.

In one embodiment, the RGB octal coding rule, each bar code may be used to represent 8 colors, and therefore, when the color code is represented by a first color ABCD four blocks ⁴⁸ can obtain color combinations. This makes it possible to find a high-contrast first color code for precise positioning no matter how colorful the color of the product packaging is, so that the camera can accurately identify the color code on the product at a longer distance.

In one embodiment, the step of determining the information recognition result of the object according to the second identification information includes: obtaining a first correspondence between the second identification information and the object information established in advance; The correspondence relationship determines the object information corresponding to the second identification information, and the information identification result of the object is determined according to the corresponding object information.

Among them, the object information can refer to the number, identification information, etc. of the object. The object information corresponds to the information recognition result, so the information recognition result of the object can be determined based on the determined object information. In addition, the object information may also be an information recognition result, that is, if the object information corresponding to the first identification information is determined, the information recognition result of the object is determined.

In this embodiment, the object information corresponding to the second identification information is determined according to the first corresponding relationship established in advance, and then the information identification result of the object can be determined. In this way, the information recognition result of the object can be accurately and quickly determined.

As shown in Fig. 3, in one embodiment, taking the object as an item and the result of the information recognition of the object as the item information as an example, the process of determining the item information may be:

S301: Define the color code coding rule and enter it into the processing unit.

S302: The item information is entered into the processing unit and the item information is bound to the identification information of the color code.

S303. The scanning terminal obtains the identification information of the color code, and inputs the identification information into the processing unit.

S304. Push item information corresponding to the identification information.

The process of inputting the coding rules and item information into the processing unit in FIG. 3 may include: inputting the coding rules of the first color code and the second color code and binding the first identification information and the second identification information with the item information. At the same time, the identification information corresponding to the two color codes can also be stored as one piece of information.

Further, the processing unit may generate identification information for a certain article according to a predefined color code rule, and then generate a color code, and display the color code through devices such as printers and displays. The processing unit receives the entered item information, and binds the item information with the second color code, that is, binds the second identification information of the second color code with the item information. When the first identification information is obtained by scanning the terminal, the first identification information can be input to the processing unit; the processing unit finds the corresponding first color code information according to the first identification information, and judges whether the two match. When the two match It is determined that the first identification information meets a preset condition. When the scanning terminal scans the second color code to obtain the second identification information, the processing unit determines the corresponding item information through the comparison index, and pushes the corresponding item information.

At the same time, when the processing unit generates identification information for the object, it can make the generated identification information unique, that is, ensure that the identification information of each object is different, and prevent information confusion. When the first identification information and the second identification information are generated separately, the first identification information can be guaranteed to be unique and the second identification information can be guaranteed to be unique; when the first identification information and the second identification information are combined as the total identification information of the object , Can guarantee the uniqueness of the total identification information.

In one embodiment, the step of acquiring the second identification information of the second color code in the position and determining the result of the information identification of the object according to the second identification information includes: if the second identification If the information acquisition fails, the partial identification information of the second color code is acquired; the information identification result of the object is determined according to the first identification information and the partial identification information.

In one embodiment, the step of determining the information recognition result of the object based on the first identification information and the partial identification information includes: integrating the first identification information and the partial identification information, Obtain spare identification information; when the spare identification information matches the predetermined candidate spare identification information, the information identification result of the object is determined according to the candidate spare identification information.

In the above two embodiments, the backup code is enabled, and when the second identification information cannot be accurately obtained, the information identification result of the object is determined by using part of the identification information and the first identification information. It can obtain accurate object information recognition results when the color code cannot be fully recognized due to reasons such as light.

In one embodiment, taking the first color code as ABCD four color blocks as an example, the first color code may be referred to as ABCD code. Taking the second color code as a color block as an example, the second color code can be called an RGB code (which can include a start code, an end code, and an RGB center code). The RGB code can be multiple barcodes. Therefore, when the RGB values of all the barcodes cannot be accurately obtained, if the RGB value of one or part of the barcode can be obtained, the first identification information and part of the identification information can be combined to determine The information recognition result of the object.

Therefore, as shown in FIG. 4, the backup code "ABCD+X" can be used for backup encoding, where X represents at least one RGB code. For example, if the complete RGB code is converted into a numerical number, it is 443. Due to some recognition abnormalities, only the red "4" or cyan "3" in the bar code can be recognized (it must be able to recognize at least one color, otherwise it cannot be recognized. Work with ABCD code), you can use the combination of "ABCD+4" or "ABCD+3" to match the pre-defined backup code, and the system will pass the recognized "ABCD+4" or "ABCD+3" The internal code is converted into the RGB code "443" to determine the information recognition result of the object, and play the function of accurate identification of the backup code.

In this embodiment, the backup code is enabled and the first color code is combined with the second color code to ensure the uniqueness of the determined information recognition result, and it can be solved that only the second color code to determine the information recognition result is not enough to meet the growing number of commodities. The problem of quantity effectively improves the scalability of the method for identifying object information of the present invention.

In one embodiment, the backup code, the location code and the security code in the foregoing embodiment can be selected according to needs. For example, if you choose not to enable the backup code, when the second identification information acquisition is not complete, you can directly prompt the object's identification information acquisition failure.

In one embodiment, because the distance between the color blocks of the barcodes is too close, it may cause unrecognition or misrecognition. The barcode spacing of ABCD codes can be customized according to the quality of the detection environment to ensure that the camera is in a bad condition. The ABCD code can be accurately captured in the environment. In addition, the size of the ABCD code can also be customized. If the camera resolution reaches 1080P, the ABCD code size can be reduced. If the camera resolution is only 720P, then the ABCD code size can be appropriately increased to ensure accurate recognition. The advantage of the adjustable spacing and size of the ABCD code is that the traditional scanning terminal must adopt some high-tech camera technologies in harsh environments, such as backlight photography, darkroom active light supplement technology, etc. However, the scanning terminal in the embodiment of the present invention does not need to bring any high-tech. The user can choose the appropriate ABCD code spacing and size according to the definition of the terminal and the application environment (for example, the environmental brightness of the vegetable farm is relatively higher than that of the supermarket. Therefore, the size of the color code of the vegetable farm product can be larger than the size of the color code of the supermarket product). Therefore, in practical applications, users do not need to choose expensive cameras, which greatly reduces the dependence on high-definition cameras.

In an embodiment, the second color code includes: a start code, an end code, and an RGB center code; the step of obtaining the second identification information of the second color code in the position includes: The position determines the start code and the end code of the second color code; obtains the RGB center code between the start code and the end code, and determines the second identification information according to the RGB value of the RGB center code.

In this embodiment, the second identification information is determined by identifying the RGB center code between the start code and the end code, and the color value in each frame is determined by the camera, and the second identification information can be determined through a predetermined correspondence relationship. The way is simple.

In one embodiment, the step of determining the second identification information according to the RGB value of the RGB center code includes: obtaining a pre-established second correspondence between RGB values and numerical numbers; and according to the second correspondence The relationship determines the numerical number of the second color code, and the second identification information is determined according to the numerical number.

In this embodiment, the numerical number of the second color code is determined according to the second correspondence relationship, so that the determination of the second identification information has a higher efficiency.

In an embodiment, the start code and the end code can be implemented as short lines as shown in FIG. 5, the horizontal line represents the start code, and the vertical line represents the end code. Of course, the start code and end code can also be expressed in other graphics or forms.

The corresponding relationship between the RGB code and the corresponding octal numerical number can be shown in Figures 6 and 7 (the corresponding relationship between the numerical number and the RGB value is shown in Table 1). Among them, the RGB center code in FIG. 6 is represented by a rectangular box, and the RGB center code in FIG. 7 is represented by a circular box, and the inside of these rectangular boxes and circular models is filled with colors corresponding to RGB values.

In one embodiment, the color of the outer frame line of the RGB center code may be different from the color of the attached object to distinguish it from the object and improve the accuracy of recognition. As shown in Figure 8, when the background (object) is white, the border of the RGB center code is black, and when the background is black, the border of the RGB center code is white. At the same time, a proper gap can be left between the barcodes.

In an embodiment, the positional relationship between the ABCD code and the RGB code may be as shown in FIG. 9, which is a schematic diagram of the target barcode, and the target barcode includes the ABCD code and the RGB code. As shown in FIG. 9, the ABCD code is set around the RGB code. After the first identification information of the ABCD code meets the preset condition, it is determined that the RGB code is inside the ABCD code. Then the scanning terminal scans the inside of the ABCD code to obtain the corresponding second identification information.

In an embodiment, as shown in FIG. 10, a method for identifying object information is provided, which includes the following steps:

S101. Acquire first identification information of the first color code of the object.

S102. Obtain predetermined first color code information of the object; when the first identification information matches the first color code information, determine that the first identification information meets a preset condition.

S103. Determine the position of the second color code of the object; the position is determined according to the first color code.

S104. Determine the start code and the end code of the second color code according to the position; obtain the RGB center code between the start code and the end code, and determine the first color code according to the RGB value of the RGB center code 2. Identification information.

S105. Obtain a pre-established first correspondence between the second identification information and the object information; determine the object information corresponding to the second identification information according to the first correspondence, and determine the object according to the corresponding object information The result of the information recognition.

In this embodiment, the position of the second color code is determined according to the first color code, so that the second identification information of the second color code can be determined more easily, and a more accurate object recognition result can be obtained.

In order to better understand the above method, take the first color code consisting of four color blocks ABCD, and the second color code consisting of a start code, an end code, and three color blocks as an example. The following describes in detail an application example of the object information identification method of the present invention. This application example simultaneously enables the functions of the positioning code and the security code of the ABCD code, and enables the backup code.

Assuming that the RGB code of a commodity G is "yellow red yellow", the corresponding numerical code is 646, and the corresponding information of the ABCD code color "cyan, blue, green" is 3312. Then the process of identifying the commodity information of commodity G can be:

1) According to a preset coding rule, the processing unit generates a corresponding product code (ie total identification information) for the product G, and converts the product code into an octal number and the corresponding color code. The color code includes ABCD code and RGB code. Since the RGB code contains two numbers 4 and 6, the product code can be determined as 64633124 or 64633126 (to ensure the uniqueness of the data, when determining the last 5 digits of the 8-bit code, set the first 3 digits to 646 to ensure The RGB center code can be uniquely determined based on the last 5 digits). At the same time, the product information is bound to the product code and stored in the processing unit.

2) The processing unit prints the product number on the product G by controlling the printer.

3) The camera captures the A, B, C, and D codes on the product G in sequence, and inputs the capture result into the processing unit. The processing unit determines the RGB value of the ABCD code, and determines the first identification information corresponding to the ABCD code according to the RGB value and the preset correspondence relationship. If the determined first identification information is 3312, it is considered that the ABCD code meets the preset condition.

4) Quickly locate the ABCD code, and roughly determine that the position of the RGB code is in the middle of the ABCD code.

5) Scan the RGB code at the corresponding position to determine the start code and end code, and then identify the RGB center code between the start code and the end code. The second identification information corresponding to the RGB center code is determined according to the determined RGB center code and the preset corresponding relationship.

6) If the determined second identification information is 646, it is determined that the verification of the second identification information is passed, and the product information corresponding to the product code is acquired as the result of the information identification of the product G.

7) If the RGB center code cannot be read directly, the backup code function will be activated. Since the ABCD code has been certified for safety, it is only necessary to correctly read one of the colors of the RGB center code, namely yellow or red. According to the ABCD+X coding rules, the backup code is 33124 or 33126. As long as one of them can be read, the system will automatically convert it into a corresponding product equal to the center code 646 according to the internal coding rules, and determine the corresponding product information.

8) The processing unit pushes the acquired product information to the user, and the user queries the product information through output devices such as displays and printers.

First of all, compared with the traditional direct recognition of RGB codes, this embodiment uses ABCD codes as positioning, security and backup codes, which greatly improves the reading speed, security level and error tolerance rate of color codes. Secondly, the audience for the camera is wide, that is, the degree of reliance on the clarity of the camera is not high. If the camera's resolution is low, you can use a large-size ABCD code; if it is a high-definition camera, you can use a small-size ABCD code. In addition, after the ABCD code is preprocessed and positioned, the camera will capture the color bar code in this area; it can greatly increase the accuracy of the camera to recognize the color bar code, and avoid the inaccurate RGB positioning or misjudgment of the product caused by the color difference of the packaging box Case.
