The above-mentioned drawings are incorporated into the specification and constitute a part of the specification, showing an embodiment consistent with the present application and used together with the specification to explain the principle of the present application.

The above-mentioned figures have shown clear embodiments of the present application, which will be described in more detail later. These figures and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments.

Exemplary embodiments are described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the attached application scope.

In the present application, the medium can be any printable object such as paper, film, wood chip, metal sheet, etc. The surface of the medium can be printed with main information including text, images, etc., and can also be printed with one or more types of image indicators. As shown in FIG. 2a, any type of image indicator includes a header portion 201 and a content data portion 202. The header portion is composed of a plurality of micro-image units 2011, wherein the micro-image unit 2011 can include The header part includes a dot pattern, and the dot clusters in the header part may be asymmetrically distributed. The header part is used to obtain a complete image pointer and identify different image pointers. The content data part 202 is also composed of a plurality of micro-image units 2021, wherein the micro-image unit 2021 may include a dot pattern, wherein the arrangement rule of the dot pattern is different from that of the header part, and the dot pattern of the header part 201 forms a rectangular array, which is used to represent the digital data of the image pointer.

The medium surface carries one or more types of image pointers, and the arrangement rules of the micro-image units of the image pointers of different types are different, wherein the arrangement rules of the micro-image units of the headers of the image pointers of different types may be different, for example, the headers of the image pointers of different types may be "L"-shaped and "7"-shaped, respectively, as shown in FIG. 2a and FIG. 2b, the headers 201 and 201' of the image pointers of different types; and/or, the sizes (rectangles) of the image pointers of different types may be different. The dimensions of the image pointers (e.g., different types of image pointers) may also be different. For example, different types of image pointers may be 4×4, 4×5, and 5×5. By changing the arrangement rules of the micro-image units in the header and/or the size of the image pointer, different types of image pointers may be combined. In addition, the content data parts of different types of image pointers, such as the content data parts 202 and 202' of different types of image pointers shown in FIG. 2a and FIG. 2b, may have the same or different micro-image unit arrangement rules.

Among them, in different application scenarios, different types of image indicators carried by the medium surface have different uses. For example, different types of image indicators can correspond to different functions. For example, the medium surface is divided into a functional area and a handwriting area, and different types of image indicators can be used respectively. Different functions in the functional area can also use different types of image indicators respectively; or, in accordance with different product feature requirements, for example: a large number of image indicators need to be used, the need to reduce printing costs, etc., or even different types of image indicators are used for new and old products; or, different types of image indicators contain different data, by using different types of For example, the first type of image pointer identifies the information of multimedia content data, such as the name, series, and identification (ID) of the multimedia content data, while the click-reading area uses the second type of image pointer, which corresponds to the information of the multimedia content data of the first type of image pointer. After scanning the first type of image pointer, the multimedia content data is downloaded according to the information of the multimedia content data, so that it can be played after scanning the second type of image pointer in the click-reading area. Of course, the image pointer that identifies the information of the multimedia content data and the image pointer in the click-reading area can also be implemented by using different image pointers of the same type.

In this application, an electronic device can be used to collect and decode image indicators of the medium surface. As shown in FIG3 , the electronic device 300 may include a processor 310, a memory 320, and an image scanning device 350, wherein the image scanning device 350 is used to collect medium surface images; the memory 320 is used to store computer execution instructions corresponding to the decoding process of the image indicators in this application; the processor 310 is used to execute the computer execution instructions stored in the memory 320 to decode the image indicators based on the medium surface images collected by the image scanning device 350.

Optionally, the electronic device 300 may also include an input/output device 340 for receiving input operations to generate input instructions/output multimedia content; optionally, the electronic device 300 may also include a wireless communication circuit unit 330 for establishing a network connection or establishing a connection with another electronic device.

The technical solution of this application is described in detail below with specific embodiments. The specific embodiments can be combined with each other without conflict, and the same or similar concepts or processes may not be described in detail in some embodiments.

Figure 4 is a flow chart of the decoding method of the image pointer provided in the embodiment of the present application. This embodiment provides a decoding method of the image pointer, the execution subject of which is an electronic device, the electronic device includes an image scanning device, and the specific steps of the decoding method of the image pointer are as follows:

S401, collecting medium surface images through an image scanning device, wherein the medium surface carries different types of image indicators, and any type of image indicator includes a header part and a content data part respectively composed of multiple micro-image units.

In this embodiment, the electronic device can scan the medium surface through its image scanning device, and collect the medium surface image at the scanned position of the medium surface during the scanning process.

S402, according to the arrangement rules of micro-image units corresponding to different types of image indicators, identify the first header of any type of image indicator from the medium surface image.

In this embodiment, since the medium surface carries different types of image indicators, and the micro-image unit arrangement rules of different types of image indicators are different, the header part of any type of image indicator can be identified from the medium surface image based on the micro-image unit arrangement rules corresponding to different types of image indicators. For the convenience of description, the identified header part is recorded as the first header part; when the first header part is identified, the type of the first image indicator to which the first header part belongs can also be confirmed according to the matched micro-image unit arrangement rules, or the type of the first image indicator to which the first header part belongs can be confirmed according to the first header part.

Among them, the arrangement rules of micro-image units of different types of image pointers are different, specifically, the arrangement rules of micro-image units of headers of different types of image pointers are different, and the arrangement rules of micro-image units of content data of different types of image pointers can be the same or different. Therefore, in this embodiment, the header of an image pointer belonging to any type can be identified from the medium surface image based on the arrangement rules of micro-image units of headers of different types of image pointers.

Specifically, the arrangement rules of the micro-image units in the headers of different types of image pointers include common arrangement rules and non-common arrangement rules. When identifying the first header from the medium surface image, the first part of the header can be found out by using the common arrangement rules of the headers of different types of image pointers. Based on the first part of the header, the remaining second part of the header can be found out by using the non-common arrangement rules of the headers of different types of image pointers, thereby obtaining the complete first header. Based on the arrangement rules used to find the first header, the type of the first image pointer can be determined.

For example, for the image pointers of the headers with two different arrangement rules of "L" type and "7" type in Figure 2a and Figure 2b, when decoding, the first part of the header that meets the common arrangement rule is first found: a dot pattern of "─" type arrangement; on the basis of identifying the first part of the header, the second part of the header is found using the non-common arrangement rule. If it satisfies the "|" type arrangement, the header is an "L" type header, and the first image pointer is determined to be the image pointer of the "L" type header. If it satisfies the "/" type arrangement, the header is a "7" type header, and the first image pointer is determined to be the image pointer of the "7" type header. Furthermore, the size of the first image pointer can be determined based on the arrangement rules of the micro-image units in the header of the first image pointer and the number of dot patterns in the header, and the type of the first image pointer can be determined, and decoding can be completed according to the arrangement rules of the content data corresponding to the type of the first image pointer.

S403, obtaining a first image pointer corresponding to the first header from the medium surface image according to the first header.

In this embodiment, after the first header is identified, the complete first image pointer to which the first header belongs can be found from the medium surface image based on the first header to perform the subsequent decoding process.

More specifically, the size of the first image pointer can be determined according to the first header, that is, the length and width of the first image pointer are respectively composed of a number of micro-image units (the dimension of the rectangular array), such as 4×4, 4×5, 5×5, etc., and then the complete first image pointer is obtained according to the size of the first image pointer.

S404, according to the coding rule corresponding to the type to which the first image indicator belongs, decode the first image indicator.

In this embodiment, after obtaining the complete first image pointer, the first image pointer can be decoded to obtain the digital data included in the content data part of the first image pointer. Optionally, based on the encoding rule corresponding to the content data part of the type to which the first image pointer belongs, the content data part in the first image pointer can be decoded using a corresponding decoding rule.

Since the arrangement rules of micro-image units in the content data parts of different types of image pointers can be the same or different, that is, the encoding rules corresponding to the content data parts of different types of image pointers can be the same or different, if the encoding rules corresponding to the content data parts of different types of image pointers are the same, the decoding rules corresponding to the same encoding rules are used to decode the content data part in the first image pointer; if the encoding rules corresponding to the content data parts of different types of image pointers are different, the decoding rules corresponding to the encoding rules corresponding to the content data part of the type to which the first image pointer belongs are used to decode the content data part in the first image pointer.

In the decoding process, since the first image indicator in the medium surface image includes not only the dot pattern of the micro-image unit, but also printing stains or optical residual images, the dot pattern of the micro-image unit that meets the arrangement rule of the micro-image unit corresponding to the type to which the first image indicator belongs can be selected from the range of the first image indicator in the decoding process according to the arrangement rule of the micro-image unit corresponding to the type to which the first image indicator belongs, and the printing stains and optical residual images can be filtered out.

In this embodiment, a scanning device of an electronic device collects a medium surface image, wherein the medium surface carries different types of image pointers, and any type of image pointer includes a header portion and a content data portion respectively composed of a plurality of micro-image units; a first header portion of an image pointer belonging to any type is identified from the medium surface image according to an arrangement rule of micro-image units corresponding to different types of image pointers; a first image pointer corresponding to the first header portion is obtained from the medium surface image according to the first header portion; and the first image pointer is decoded according to a coding rule corresponding to the type to which the first image pointer belongs. In this embodiment, the image scanning device of the electronic device can decode any type of image pointer on the medium surface after scanning, so that the electronic device supports different types of image pointers. It can also drive the electronic device to perform different functions according to different types of image pointers by carrying different types of image pointers on the medium surface.

In an optional embodiment, as shown in FIG5 , the medium surface 500 includes a function area 501 and a handwriting area 502, wherein both the function area 501 and the handwriting area 502 carry image pointers (not shown in the figure). The function area 501 may be a point-reading area, and may also provide multiple functions, including but not limited to: point-reading function, handwriting function, saving function, etc. If it is determined that the image scanning device is currently located in the function area 501, that is, the image scanning device scans the image pointer of a function of the function area 501, then after decoding the image pointer, the corresponding target function is determined according to the decoding result, and the instruction corresponding to the target function is executed; and the handwriting area 502 is used for handwriting through the image scanning device.

Optionally, the image pointer in the function area and the image pointer in the handwriting area may use different types of image pointers, for example, the function area uses a first type of image pointer, and the handwriting area uses a second type of image pointer, so that the function area and the handwriting area can be directly distinguished according to the type of image pointer; Optionally, on the basis that the image pointer in the function area and the image pointer in the handwriting area can use different types of image pointers, the decoding result of the first type of image pointer can correspond to the first preset code segment, and the decoding result of the second type of image pointer can correspond to the second preset code segment, for example, the total number of the first type of image pointer and the second type of image pointer is 10,000, of which code segments 0~2999 correspond to the first type of image pointers, and code segments 3000~9999 correspond to the second type of image pointers. Therefore, the functional area and the handwriting area can also be distinguished based on the code segment where the decoding result is located; of course, the image pointers in the functional area and the image pointers in the handwriting area can also use the same type of image pointers, and the functional area and the handwriting area can be distinguished by the code segment where the decoding result of the image pointer is located. For example, there are a total of 10,000 image pointers of the same type used in the functional area and the handwriting area, of which code segments 0~2999 are set as image pointers for the functional area, and code segments 3000~9999 are set as image pointers for the handwriting area.

Furthermore, the method also includes:

According to the first header obtained in the decoding process or the type of the first image pointer, or according to the decoding result of the first image pointer, it is determined whether the image scanning device is currently located in the handwriting area.

In this embodiment, the first header can be obtained in the process of decoding the first image pointer, and the type of the first image pointer is determined. According to the first header or the type of the first image pointer, or based on the decoding result of the first image pointer, it can be judged whether the image scanning device of the electronic device is currently located in the handwriting area. The judgment method can adopt at least one of the following optional methods:

Method 1: judging whether the image scanning device is currently located in the handwriting area according to the type of the first image pointer, wherein the image pointer in the function area and the image pointer in the handwriting area use different types of image pointers;

Among them, since the image pointer in the function area and the image pointer in the handwriting area use different types of image pointers, the image scanning device can directly judge whether the image scanning device is currently in the handwriting area or the function area according to the type of the first image pointer when scanning the first image pointer.

Method 2: Based on the relationship between the first image pointer and the second image pointer adjacent to the first image pointer, determine whether the image scanning device is currently located in the handwriting area;

Since the image pointers in the handwriting area need to provide coordinates, the adjacent image pointers are different, and the adjacent image pointers meet certain rules, which are recorded as the first preset rules. The first preset rule is the arrangement rule between adjacent image pointers in the handwriting area, for example, some micro-image units of adjacent image pointers have a certain relative position relationship. If the second image pointer adjacent to the first image pointer is different from the first image pointer, and the first image pointer and the second image pointer meet the first preset rule, it is determined that the image scanning device is currently located in the handwriting area.

Method 3: Based on the code segment where the decoding result is located and the preset code segment, determine whether the image scanning device is currently located in the handwriting area.

The image pointer in the function area and the image pointer in the handwriting area may be of different types or of the same type. In both cases, the image pointer in the function area and the image pointer in the handwriting area may be configured with code segments corresponding to the image pointer in the function area and the image pointer in the handwriting area in advance. For example, the first preset code segment is the decoded result of the image pointer in the handwriting area. For example, if the second preset code segment is the code segment corresponding to the decoding result of the image pointer in the non-handwriting area (the area other than the handwriting area, including the function area), if the decoding result of the first image pointer falls into the first preset code segment, it is determined that the image scanning device is currently located in the handwriting area, or if the decoding result of the first image pointer does not fall into the second preset code segment, it is determined that the image scanning device is currently located in the handwriting area.

Method 4: Determine whether the image scanning device is currently located in the handwriting area based on whether the image scanning device has selected the handwriting recognition function in the function area.

Among them, the function area includes a handwriting recognition function. Before the image scanning device scans the first image pointer, if the user needs to activate the handwriting recognition function, the electronic device can be operated to make the image scanning device scan the image pointer included in the handwriting recognition function in the function area, thereby triggering the activation of the handwriting recognition function, and then scanning the first image pointer to confirm that the image scanning device is currently located in the handwriting area.

Method 5: Determine whether the image scanning device is currently located in the handwriting area based on the specific micro-image unit in the first image pointer or the arrangement rule of the micro-image unit in the first header.

Among them, a specific encoding rule can be used in a specific micro-image unit in the image pointer to distinguish whether the image pointer is located in the handwriting area or the non-handwriting area (including the functional area). For example, the dot pattern in the specific micro-image unit is offset in a specific direction, such as the dot pattern of the specific micro-image unit in the image pointer of the handwriting area is offset in the up and down direction, and the dot pattern of the specific micro-image unit in the image pointer of the functional area is offset in the left and right direction.

Furthermore, if the specific micro-image unit in the first image pointer meets the first coding rule, it is determined that the image scanning device is currently located in the handwriting area, wherein the first coding rule is the arrangement rule of the specific micro-image unit of the image pointer in the handwriting area; or, if the specific micro-image unit in the first image pointer does not meet the second coding rule, it is determined that the image scanning device is currently located in the handwriting area, wherein the second coding rule is the arrangement rule of the specific micro-image unit of the image pointer in the non-handwriting area.

Based on the above embodiments, if it is determined that the image scanning device is currently located in the handwriting area, the sensing mode and/or sensing parameters of the image scanning device can be adjusted, such as increasing the frame rate, etc. In addition, the decoding algorithm can be adjusted and the coordinate data can be generated.

In addition, the coordinates represented by the first image pointer can be obtained by decoding, and since the image scanning device is constantly moving, the coordinates represented by the first image pointer are constantly obtained, and the first movement trajectory of the image scanning device can be continuously obtained based on the obtained coordinates. Further, the first movement trajectory can be displayed on the display device of the electronic device, or sent to a computer connected to the electronic device. The display device connected to the sub-device for communication and display; the first movement trajectory can also be recognized as text or image, for example, the first movement trajectory is judged and converted by an artificial intelligence model to realize the recognition of text or image, and then the recognition result can be played as voice and/or displayed on the display device, thereby realizing the handwriting function of the electronic device.

Optionally, the color of the first moving track can also be set, for example, by selecting the track color in the function area through the image scanning device of the electronic device (scanning the image indicator corresponding to the specific color).

Optionally, the electronic device may also include a physical refill, which may contain ink or be a pencil refill, and may produce handwriting on the surface of the medium. That is, when the electronic device writes in the handwriting area, the image scanning device scans the image pointer carried on the surface of the medium to generate data of the first moving trajectory, and at the same time, the physical refill may produce real handwriting on the surface of the medium.

Optionally, the medium can be a flexible transparent or opaque film or soft pad made into a writing medium with image indicators, which can be placed or attached to a suitable plane, such as glass, display, desktop, etc., for easy movement and installation. The handwriting function of replacing the electronic whiteboard or touch screen can be realized on the surface of the medium through the above-mentioned electronic equipment, avoiding the problem of inconvenience in movement and installation caused by the limitation of hardware size and peripheral equipment of similar electronic whiteboards or touch screens.

In an optional embodiment, the electronic device can also provide an erase function in addition to the handwriting function. Optionally, the erase function can be provided in the function area, and the electronic device can scan the erase function (corresponding image pointer) in the function area through an image scanning device, thereby triggering the erase function. Alternatively, the electronic device is a device dedicated to erasing handwriting, such as an electronic eraser.

Furthermore, if the image scanning device has selected the erase function in the function area, or the electronic device is a device for erasing handwriting, then after the image scanning device captures the medium surface image, the above decoding process is executed, the coordinates of the first image pointer are obtained based on the decoding result, and the second movement track of the image scanning device is obtained based on the coordinates, so as to erase the content within the coverage range of the second movement track in the display device, especially erase the handwritten content within the coverage range of the second movement track (the first movement track or the recognition result corresponding to the first movement track).

Optionally, if the electronic device is an electronic device dedicated to erasing handwriting, in the scenario where the electronic device with a physical refill is used to write on a medium surface, the electronic device dedicated to erasing handwriting may also include a physical erasing module. For example, the physical erasing module may be made of felt, velvet, leather, rubber, etc., and may erase handwriting produced by the physical refill on the medium surface.

Based on any of the above embodiments, considering that the functions in the function area are limited, in this embodiment, instructions can be input by handwriting to expand the functions in the function area. The specific process can be as follows:

In response to the triggering operation of the handwriting instruction, the coordinates of the first image pointer are obtained, the third movement trajectory of the image scanning device is obtained based on the coordinates, and the third movement trajectory is identified;

If it is determined that the recognition result of the third moving track is a preset instruction, the preset instruction is played by voice;

In response to the confirmation operation of the default instruction, the default instruction is executed.

In this embodiment, when the user needs a handwriting instruction, the handwriting instruction trigger operation can be performed. For example, the handwriting instruction function can be set in the function area, and the electronic device can scan the handwriting instruction function (corresponding image pointer) in the function area through an image scanning device to trigger the handwriting instruction function; or a command key can be set on the electronic device, and the user can trigger the handwriting instruction function by triggering the command key (for example, long pressing the command key). Furthermore, the user can write on the surface of the medium (which can be a handwriting area) through an electronic device. During the handwriting process, the image scanning device can collect the image of the medium surface, execute the method described in S401-S404 above, obtain the coordinates of the first image pointer based on the decoding result, obtain the third movement trajectory of the image scanning device based on the coordinates, and identify the third movement trajectory, such as identifying the third movement trajectory through an artificial intelligence model. If the identification result is a preset instruction, the preset instruction is played by voice, and the user can trigger the confirmation operation of the preset instruction, and then execute the preset instruction. For example, the user writes "save" on the surface of the medium through an electronic device. After identifying the trajectory, it can be determined that the instruction is a save instruction.

In one example, the electronic device includes a command key and a confirmation key. The user long presses the command key to trigger the handwriting command function. The user writes the required command, such as "save", on the surface of the medium while long pressing the command key. After the electronic device recognizes the track, it can determine that the command is a save command and play it by voice. The user can trigger the confirmation key to confirm the save command, and then the electronic device can execute the corresponding save process.

On the basis of any of the above embodiments, when the electronic device realizes the click-to-read function, the click-to-read content (multimedia content data) needs to be stored in the electronic device in advance, which will have the disadvantage of being unable to update, and needs to be sent with a memory card, which will cause incompatibility and difficult to store problems, or the electronic device is connected to the Internet through a computer to download, which will require a computer and operating capabilities, so In this embodiment, the networking information such as the service set identifier SSID and the password password can be used as the decoding result of the image indicator, and then the network is connected according to the networking information. Specifically, after decoding the first image indicator, if the decoding result is the default networking information, a network connection is established with the target network device (such as a wireless access point AP, a router Router, etc.) according to the networking information.

Optionally, the network information can be written through the handwriting function of the electronic device. After the mobile track is identified, the network information is obtained and voice is played. After confirmation by the user, a network connection can be established with the target network device (such as wireless access point AP, router, etc.) based on the network information.

Based on the above embodiments, after the electronic device is connected to the network, the required multimedia content data can be downloaded and stored in the electronic device.
