Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The object information identification method provided by the application can be applied to the application environment shown in fig. 1. The scanning terminal 101 obtains corresponding first identification information by scanning the color code, and uploads the first identification information to the processing unit 102, and the processing unit 102 determines the position of the second color code when the first identification information meets the preset condition, obtains the second identification information, and 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 a smartphone and a scanner. The processing unit 102 may be a server, a personal computer, a laptop, a smartphone, a tablet, a POS machine, 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 embodiment of the invention provides an object information identification method and device, computer equipment and a storage medium. The following description will be made in detail by taking the method as an example applied to the processing unit 102 in fig. 1.

In one embodiment, as shown in fig. 2, there is provided an object information identification method, including the steps of:

s201, first identification information of a first color code of an object is obtained.

Wherein an object refers to something that can display or present a color code. May refer to an article, a commodity, a person, a picture displayed on a screen, etc. The first color code may be displayed on the object or may be attached to the object.

The first color code refers to a bar code expressed by a color form, and can be a color one-dimensional code, a color two-dimensional code, and other forms. Meanwhile, the first color code may comprise one bar code (a vertical line or a horizontal line), or may comprise two or more bar codes.

The first identification information is color (which can be converted into RGB values, etc.), number, form, and other information included in the color code obtained by identifying the first color code.

Further, the initial data obtained by the color code can be quantized to obtain data, which is convenient for subsequent information processing.

In addition, the obtaining of the first identification information of the first color code may be realized by scanning the first color code through a terminal having a scanning function, or may be realized in other manners. These scanning terminals may be provided with a camera (and thus may be considered to scan the first color code by means of the camera). Among them, a CAMERA (CAMERA or WEBCAM) is also called a computer CAMERA, a computer eye, an electronic eye, etc., is a video input device, and is now widely used in many fields such as video conferencing, telemedicine, real-time monitoring, etc.

S202, when the first identification information meets a preset condition, determining the position of a second color code of the object; the position is determined from the first color code.

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

When the first identification information meets the preset condition, the second color code is determined, the encryption function of the first color code is used, and the first color code can be called as a security code. The position of the second color code is determined on the basis of the first color code, which is used for the positioning function of the first color code, and the first color code can be called positioning code.

The encryption function of the first color code can improve the information security and the anti-counterfeiting capability 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 operation of acquiring the second identification information is not carried out. The processing mode can greatly improve the information security of the object. Of course, the developer can choose whether to enable the function of the security code and whether to open the security code after use. That is, if the developer selects not to enable the security code, the corresponding information identification result may be determined directly according to the second identification information when the second identification information is acquired without the judgment of the first identification information.

In addition, the judgment of whether the first identification information satisfies the preset condition may be to judge whether the first identification information satisfies the condition in terms of size, number, and the like, may also be to judge whether the first identification information matches a preset threshold value, and may of course be in other manners.

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

In addition, the first color code and the second color code may be represented in various forms, for example: the representation can be directly through numbers, characters or graphs. The graphical representation can be realized through various graphs, such as: it can be represented by a rectangular box or by a circular box.

Further, the implementation process of determining the position of the second color code may be: the first identification information of the first color code may include position information of the second color code, so that the position of the second color code can be determined based on the first identification information. Or the first color code and the second color code have a certain position relation, 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 from the first color code may be an exact position or an approximate position of the second color code.

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

The information recognition result of the object may be information such as article information (for example, information such as computer size, model, date of shipment), commodity price, and commodity model. The information identification result and the second identification information can have a corresponding relation, and the corresponding information identification result can be determined according to the second identification information and the corresponding relation.

In addition, the second identification information of the second color code may be obtained by scanning the second color code through a terminal having a scanning function, as in the case of obtaining the first identification information. Also, it may be implemented in other ways.

At present, when information codes such as one-dimensional codes and two-dimensional codes are identified, a scanning head of a scanning terminal needs to be close to the information codes to capture information. This does not allow for rapid access to product information for certain industries or in special circumstances. The first color code of the embodiment has both an encryption function and a positioning function, and can more accurately and easily determine the second identification information of the second color code, so that a more accurate object identification result can be quickly obtained, and the fault-tolerant rate of information identification is greatly reduced.

The first color code information may be artificially defined or calculated according to a certain algorithm.

Before identifying the object information, corresponding first color code information (as verification information) may be set for the object, and if the identified first identification information matches with the predetermined first color code information, the first identification information may be considered to meet a preset condition. According to the embodiment, whether the first identification information meets the condition can be accurately and quickly determined in such a mode, and the information identification efficiency of the object is improved.

In one embodiment, the first color code may be represented by four color blocks of ABCD (of course, the first color code may include more or less color blocks, and may be represented in other manners). The RGB values of these color blocks may be given different numerical numbers. When the RGB values of the first color code color block are determined, the corresponding numerical value number is determined, and then the first identification information is determined. The following table 1 shows the corresponding relationship between different RGB values and numerical numbers. To facilitate color capture by the camera, the maximum 255 and minimum 0 values of the RGB function may be taken to define the color, e.g., eight colors may correspond to 0-7 octal numbers, as in table 1 (which may also be arranged in binary, decimal, hexadecimal, etc. depending on the pixels of the camera). The colors defined by the maximum value and the minimum value are pure colors, so that the identification method has high identification degree, can effectively improve the accuracy of identification information acquisition, and further improves the accuracy of the information identification result of the object. Of course, the RGB values corresponding to these numerical numbers may be other values.

Numerical numbering	R	G	B	Colour(s)
					0	0	0	0	Black color
1	0	0	255	Blue color
					2	0	255	0	Green colour
3	0	255	255	Cyan color
					4	255	0	0	Red colour
5	255	0	255	Magenta color
					6	255	255	0	Yellow colour
7	255	255	255	White colour

TABLE 1 correspondence table of RGB values and octal number

The RGB color scheme is a color standard in the industry, and various colors are obtained by changing three color channels of red (R), green (G) and blue (B) and superimposing them on each other. This color standard covers almost all colors that human vision can perceive, and is one of the most widely used color systems at present. The RGB function, when executed successfully, returns the color determined by the specified component, represented by a long integer. The RGB three channel requirements are as follows:

in part	Description of the invention
		red	The necessary parameters; an Integer type; numerical ranges: 0 to 255; red component representing colour
green	The necessary parameters; an Integer type; numerical ranges: 0 to 255; green component representing colour
		blue	The necessary parameters; an Integer type; numerical ranges: 0 to 255; blue component representing color

TABLE 2 RGB Trichannel requirements

In one embodiment, the first color code information and the first color code information may be information constituted by numerical values, and the numerical values corresponding to the first color code information may be stored in the processing unit in advance. If the numerical value number in the first identification information corresponds to the numerical value number in the first color code information, and the numerical value numbers can be considered to be matched with each other, the first identification information is judged to meet the preset condition; if the value number in the first identification information does not correspond to the value number in the first color code information, it can be determined that the first identification information does not satisfy the preset condition.

In one embodiment, each barcode may be represented by 8 colors according to the RGB encoding rule of octal, and thus, when the first color code is represented by four color blocks of ABCD, 4 may be obtained⁸And (4) combining colors. Therefore, no matter how gorgeous and colorful the color of the commodity package, the first color code with high contrast can be found for accurate positioning, so that the camera can accurately identify the color code on the commodity at a longer distance.

In one embodiment, the step of determining the information recognition result of the object based on the second recognition information includes: acquiring a first corresponding relation between pre-established second identification information and object information; and determining object information corresponding to the second identification information according to the first corresponding relation, and determining an information identification result of the object according to the corresponding object information.

The object information may refer to the number, identification information, and the like of the object. The object information corresponds to the information recognition result, so that the information recognition result of the object can be determined based on the determined object information. In addition, the object information may be an information recognition result in which the object information corresponding to the first recognition information is determined and the object is determined.

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

As shown in fig. 3, in an embodiment, taking the object as an article and the information identification result of the object as article information as an example, the process of determining the article information may be:

and S301, defining the coding rule of the color code and recording the coding rule into a processing unit.

And S302, inputting the article information into the processing unit and binding the article information with the identification information of the color code.

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

And S304, pushing the article information corresponding to the identification information.

The process of entering the coding rules and item information into the processing unit in fig. 3 may include: and inputting 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 article information. Meanwhile, the identification information corresponding to the two color codes can also be stored as one piece of information.

Furthermore, the processing unit can generate identification information for a certain article according to a predefined color code rule, further generate a color code, and display the color code through a printer, a display and the like. The processing unit receives the input article information, and binds the article information with the second color code, namely binds the second identification information of the second color code with the article information. When the first identification information is acquired through the scanning terminal, the first identification information can be input into the processing unit; the processing unit finds corresponding first color code information according to the first identification information, judges whether the first color code information and the corresponding first color code information are matched, and judges that the first identification information meets a preset condition when the first color code information and the corresponding first identification information are matched. When the scanning terminal scans the second color code to obtain the second identification information, the processing unit determines the corresponding article information by comparing the indexes, and pushes the corresponding article information.

Meanwhile, when the processing unit generates the identification information for the objects, the generated identification information can be unique, namely the identification information of each object is ensured to be different, and information confusion is prevented. When the first identification information and the second identification information are generated separately, the first identification information can be ensured to be unique and the second identification information can be ensured to be unique respectively; when the first identification information and the second identification information are combined as the total identification information of the object, the uniqueness of the total identification information can be ensured.

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

In one embodiment, the step of determining an information recognition result of the object based on the first recognition information and the partial recognition information includes: integrating the first identification information and the partial identification information to obtain standby identification information; and when the spare identification information is matched with the predetermined candidate spare identification information, determining the information identification result of the object according to the candidate spare identification information.

In the two embodiments, the spare code is used, and when the second identification information cannot be accurately acquired, the information identification result of the object is determined through part of the identification information and the first identification information. An accurate object information recognition result can be obtained when the color code cannot be completely recognized due to light and the like.

In one embodiment, the first color code is for example four color blocks of ABCD, which can be referred to as ABCD code. Taking the second color code, which is also a color block as an example, the second color code may be referred to as an RGB code (which may include a start code, an end code, and an RGB center code). The RGB code may be a plurality of barcodes, and therefore, when the RGB values of all the barcodes cannot be accurately acquired, if the RGB values of one or a part of the barcodes can be acquired, the first identification information may be combined with a part of the identification information to determine the information identification result of the object.

Thus, as shown in fig. 4, the spare code may be encoded in the form of a spare code "ABCD + X", where X represents at least 1 RGB code. For example, if 443 is the value after the complete RGB code is converted into the numerical value number, because of some identification abnormality, only red "4" or cyan "3" in the barcode can be identified (at least one color must be identified, otherwise, the color cannot be matched with the ABCD code), the combination of ABCD +4 "or ABCD + 3" and the predefined spare code can be matched, and the system converts the identified ABCD +4 "or ABCD + 3" into the RGB code "443" through the internal coding, thereby determining the information identification result of the object and playing the function of accurately identifying the spare code.

The embodiment starts the standby code, combines the first color code and the second color code, can ensure the uniqueness of the determined information identification result, can solve the problem that the information identification result determined by the second color code is not enough to meet the increasing number of commodities, and effectively improves the expansibility of the object information identification method.

In one embodiment, the backup code, as well as the location code and security code of the previous embodiments, may be selected for enablement as desired. For example, if the standby code is selected not to be enabled, when the second identification information is not completely acquired, the failure of the acquisition of the identification information of the object may be directly prompted.

In one embodiment, the situation that identification cannot be performed or identification errors are caused due to the fact that the distance between the color blocks among the bar codes is too close, the bar code spacing of the ABCD codes can be customized according to the quality of the detected environment, and the fact that the ABCD codes can be accurately captured by a camera under the severe environment is guaranteed. In addition, the size of ABCD code can also be customized, if the camera definition reaches 1080P, then ABCD code size can reduce, if the camera definition only has 720P, then just can suitably increase the size of ABCD code to ensure accurate discernment. The advantage of the adjustable space and size of the ABCD code is that: the traditional scanning terminal must adopt some high-tech camera shooting technologies in severe environment, such as backlight shooting, darkroom active light supplement technology and the like. The scanning terminal in the embodiment of the invention does not need to carry any high and new technology, and a user can automatically select a proper ABCD code distance and size according to the definition and the application environment of the terminal (for example, the environmental brightness of a vegetable field is lower than that of a supermarket, so that the color code of the commodity in the vegetable field can be larger than that of the commodity in the supermarket). Therefore, in practical application, a user does not need to select a camera with high price, and the dependence on the high-definition camera is greatly reduced.

In the embodiment, the second identification information is determined by identifying the RGB center code between the start code and the end code, the color value in each frame is determined by the camera, the second identification information can be determined by the predetermined corresponding relation, and the determination mode is simple.

In one embodiment, the step of determining the second identification information according to RGB values of the RGB center code includes: acquiring a second corresponding relation between the pre-established RGB value and the numerical value number; and determining the numerical value number of the second color code according to the second corresponding relation, and determining the second identification information according to the numerical value number.

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

In one embodiment, the start code and the end code may be implemented as short lines as shown in FIG. 5, with the horizontal lines representing the start code and the vertical lines representing the end code. Of course, the start code and the end code may be represented by other figures or forms.

The correspondence of the RGB code to the corresponding octal value number may be as shown in fig. 6 and 7 (the correspondence of the value number to the RGB value is as shown in table 1). The RGB center code of fig. 6 is represented by a rectangular frame, and the RGB center code of fig. 7 is represented by a circular frame, and these rectangular frames and circular lines are filled with colors corresponding to RGB values.

In one embodiment, the color of the RGB center code outline may be different from the color of the attached object to distinguish the RGB center code outline from the object, so as to improve the accuracy of recognition. As shown in fig. 8, when the background (object) is white, the frame of the RGB center code is black, and when the background is black, the frame of the RGB center code is white. Meanwhile, a proper gap can be left between the bar codes.

In one embodiment, the positional relationship between the ABCD code and the RGB code may be as shown in fig. 9, and fig. 9 is a schematic diagram of an object barcode, which includes the ABCD code and the RGB code. As shown in fig. 9, the ABCD code is disposed around the RGB code, and after the first identification information of the ABCD code meets a preset condition, the RGB code is determined to be inside the ABCD code. The scanning terminal scans the inside of the ABCD code and can acquire the corresponding second identification information.

In one embodiment, as shown in fig. 10, there is provided an identification method of object information, including the steps of:

s101, first identification information of a first color code of an object is obtained.

S102, obtaining predetermined first color code information of the object; and when the first identification information is matched with the first color code information, judging that the first identification information meets a preset condition.

S103, determining the position of a second color code of the object; the position is determined from the first color code.

S104, determining a start code and an end code of the second color code according to the position; and acquiring an RGB (red, green and blue) center code between the start code and the end code, and determining the second identification information according to the RGB value of the RGB center code.

S105, acquiring a first corresponding relation between pre-established second identification information and object information; and determining object information corresponding to the second identification information according to the first corresponding relation, and determining an information identification result of the object according to the corresponding object information.

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 identification result can be obtained.

For better understanding of the above method, the first color code is composed of four color blocks of ABCD, and the second color code is composed of a start code, an end code, and 3 color blocks. The following describes an application example of the identification method of the object information of the present invention, which enables the positioning code and the security code of the ABCD code and enables the spare code at the same time.

Suppose the RGB code of a certain product G is "yellow-red-yellow", the corresponding numerical code is 646, and the ABCD code color "cyan-blue-green" corresponds to the information 3312. The process of identifying the goods information of the goods G may be:

1) according to a preset coding rule, the processing unit generates a corresponding commodity code (namely total identification information) for the commodity G, and converts the commodity code into an octal number and a corresponding color code. Wherein the color code comprises an ABCD code and an RGB code. Since the RGB code contains two digits, 4 and 6, the product code can be determined as 64633124 or 64633126 (to ensure the uniqueness of the data, when the last 5 bits of the 8-bit code are determined, the first 3 bits are set to 646, so as to ensure that the RGB central code can be uniquely determined according to the last 5 bits). Meanwhile, the commodity information and the commodity code are bound and stored in the processing unit.

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

3) The camera captures A, B, C and D codes on the commodity G in sequence, and the captured result is input into the processing unit. The processing unit determines the RGB value of the ABCD code, determines first identification information corresponding to the ABCD code according to the RGB value and a preset corresponding relation, and if the determined first identification information is 3312, the ABCD code is considered to meet a preset condition.

4) The fast positioning is carried out through the ABCD code, and the position of the RGB code is approximately determined to be in the middle of the ABCD code.

5) And scanning the RGB codes at the corresponding positions, determining a start code and an end code in the RGB codes, and further identifying an RGB center code between the start code and the end code. And determining second identification information corresponding to the RGB center code according to the determined RGB center code and a preset corresponding relation.

6) If the determined second identification information is 646, the second identification information is judged to pass the verification, and the commodity information corresponding to the commodity code is acquired as the information identification result of the commodity G.

7) If the RGB center code can not be directly and correctly read, the function of the standby code is started. Since the ABCD code has been securely authenticated, only one of the colors of the RGB center code, i.e., yellow or red, needs to be read correctly. The spare code is 33124 or 33126 according to the encoding rule of ABCD + X. If only one of them can be read, the system will automatically convert it into the corresponding merchandise equal to the center code 646 according to the inner coding rule and determine the corresponding merchandise information.

8) The processing unit pushes the acquired commodity information to a user, and the user inquires the commodity information through output equipment such as a display and a printer.

Firstly, compared with the traditional direct identification of RGB codes, the present embodiment uses ABCD codes as positioning, security and backup codes, which greatly improves the reading speed, security level and fault tolerance of color codes. Secondly, the audience degree to the camera is wide, namely the definition dependence on the camera is not high. If the camera definition is low, a large-size ABCD code can be used; in case of a high-definition camera, a small-sized ABCD code may be used. In addition, after the ABCD code is preprocessed and positioned, the camera can capture the color bar code in the area; the accuracy of recognizing the color bar code by the camera can be greatly increased, and the condition that RGB positioning is not accurate or products are misjudged due to color difference of the packaging box is avoided.
