Description

Technical Field

[0001] The present invention relates to the field of computer processing technology, and in particular to a registration method, a registration component, an electronic device and a readable storage medium. Background Art

[0002] The registration process is to obtain the conversion relationship between one coordinate system and another coordinate system through a certain algorithm.

[0003] When using a camera to locate the positioning target, the position and posture of the positioning device on the positioning target is always obtained through the camera's image data, and then the positioning target and the positioning device are processed by tooling, and the conversion relationship between the coordinate system of the positioning target and the coordinate system of the positioning device is obtained through the tooling parameters.

[0004] However, in some cases, both the positioning device and the positioning target can only be made of plastic or resin. Based on this, due to the limitations of the manufacturing materials, the processing technology of the positioning device and the multiple processing steps of the integrated processing of the positioning target and positioning device often lead to processing accuracy not matching the structural design accuracy, resulting in large errors in the use of processing parameters (for example, errors of 1-2mm). As a result, the conversion relationship between the positioning target and the positioning device obtained through tooling parameters will not be accurate enough, introducing large errors in the subsequent positioning and navigation process.

[0075] (2) The registration method, registration assembly, electronic device, and readable storage medium of the present invention are manufactured using high-precision machine tools, which allow the use of metal materials for manufacturing, eliminating the problem of poor precision caused by plastics or resins during the processing process, for example, the accuracy can be less than one thread;

[0083] Figure 5 A schematic diagram of a registration component according to an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0084] The technical solution of the present invention will be further described in detail below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as limiting the present invention.

[0085] In an embodiment of the present invention, a registration method is provided, which can realize the registration process between a positioning target and a positioning device by registering a tool.

[0086] The positioning target is the object to be located. Typically, a positioning device uses a camera (e.g., an RGB camera) to identify the location of the positioning target. Therefore, the positioning process requires understanding the conversion relationship between the two (i.e., completing the registration process). For example, the positioning target can include a magnetic stimulation device, an electrical stimulation device, a light stimulation device, a mechanical wave stimulation device, etc.

[0087] The active surface of a positioning target is the surface on which the positioning target affects its treatment target. For example, for a magnetic stimulation device, the active surface is the surface of the generated magnetic field. Specifically, the active surface of a figure-eight magnetic stimulation coil is the surface closest to the treatment target, which is a flat surface, and the center point of this active surface is the center point of the area enclosed by the figure-eight shape. The active surface of a butterfly-shaped magnetic stimulation coil is the surface closest to the treatment target, which is a curved surface formed by two planes at an angle, and the center point of this active surface is the midpoint of the intersection of the two planes.

[0088] The positioning device serves to locate the positioning target. For example, the positioning device can be captured by a camera to determine its spatial data (e.g., position information). The positioning device can be a positioning plate. The positioning device can be made of plastic or resin.

[0089] The positioning target can be provided with one, two, three or more positioning devices. Setting more positioning devices can expand the field of view that the camera can capture and improve the efficiency of the operation process.

[0090] The registration tool is used to register the coordinate system of the positioning device and the positioning target.

[0091] The camera in this article is a camera that can provide grayscale images, including grayscale cameras, color (RGB) cameras, depth cameras and any combination thereof.

[0092] like Figure 1 As shown, the registration method includes:

[0093] S1 sets a first marking point and a first recognition pattern on the registration tool, and determines the spatial data of the first marking point;

[0094] S2 sets a second marking point and a positioning device on the positioning target, and determines spatial data of the second marking point, wherein the positioning device includes a second recognition pattern;

[0095] S3 acquires image data through a camera, and determines spatial data of a first recognition pattern and spatial data of a second recognition pattern based on the image data, and determines first conversion data between the spatial data of the positioning target and the spatial data of the positioning device based on the spatial data of the first recognition pattern, the spatial data of the second recognition pattern, the spatial data of the first marking point, and the spatial data of the second marking point.

[0096] The embodiment of the present invention implements the registration process by registering the tooling, determines the conversion relationship between the spatial data of the positioning target and the spatial data of the positioning device (such as the first conversion data), and to a certain extent reduces the problem of poor accuracy caused by relying on tooling parameters to implement the registration process.

[0097] The first conversion data may be a first conversion matrix Z1.

[0098] The first recognition pattern is used by the camera to capture image data of the registration tooling. The shape of the first recognition pattern includes at least one of a regular pattern and an irregular pattern. The regular pattern includes at least one of a circle, an ellipse, a rectangle, a square, a polygon, and a triangle arranged in a regular pattern, and ChArUco. The irregular pattern includes a logo arranged in a regular pattern. The embodiments of the present invention do not limit the specific shape of the pattern, and those skilled in the art may select it as needed. The spatial data of the first recognition pattern includes a posture matrix of the first recognition pattern.

[0099] The second recognition pattern is used for capturing image data of the positioning device by the camera. The shape of the second recognition pattern includes at least one of a regular pattern and an irregular pattern. The regular pattern includes at least one of a circle, an ellipse, a rectangle, a square, a polygon, and a triangle arranged in a regular pattern, and ChArUco. The irregular pattern includes a logo arranged in a regular pattern. The embodiments of the present invention do not limit the specific shape of the pattern, and those skilled in the art may select it as needed. The spatial data of the second recognition pattern includes a posture matrix of the second recognition pattern.

[0100] In one example, in S3, such as Figure 2 As shown, acquiring image data through a camera and determining the spatial data of the first recognition pattern and the spatial data of the second recognition pattern based on the image data includes:

[0101] S31 aligns the first marking point of the registered tooling with the second marking point of the positioning target, obtains image data when the first marking point and the second marking point are aligned through the camera, and obtains spatial data of the first recognition pattern and the second recognition pattern when the first marking point and the second marking point are aligned through the image data.

[0102] Accordingly, in S3, if Figure 2 As shown, determining first conversion data between spatial data of the positioning target and spatial data of the positioning device based on spatial data of the first recognition pattern, spatial data of the second recognition pattern, spatial data of the first marking point, and spatial data of the second marking point includes:

[0103] S32 converts the spatial data of the first marking point into spatial data in a second recognition pattern coordinate system of the positioning device based on the spatial data of the first recognition pattern and the spatial data of the second recognition pattern;

[0104] S33 determines first conversion data between the spatial data of the positioning target and the spatial data of the positioning device based on the spatial data in the second recognition pattern coordinate system and the spatial data of the second marking point.

[0105] In an embodiment of the present invention, the spatial data of the first marking point is first converted to the second recognition pattern coordinate system of the positioning device, and then the spatial data of the first marking point and the second marking point are used to determine the conversion relationship between the spatial data of the positioning target and the positioning device.

[0106] The first marking point includes at least one first marking point. For example, the number of the first marking points is 1, 2, 3, 4 or more. The positions of the first marking points can be set as needed.

[0107] The spatial data of the first marking point includes the position coordinates of the first marking point in the first recognition pattern coordinate system.

[0108] The second marking point is located on the active surface of the positioning target. The second marking point includes at least one second marking point. For example, the number of second marking points is 1, 2, 3, 4, or more. The number of first marking points and the number of second marking points can be the same or different. The position of the second marking point can be set as needed.

[0109] The spatial data of the second marking point includes the position coordinates of the second marking point in the positioning target coordinate system.

[0110] The registration tooling can have various forms, including registration plates and registration pens. In one example, the registration plate is in the form of a rectangular parallelepiped as a whole, and a first identification pattern is provided on one side of the rectangular parallelepiped (e.g., the side with the largest area). In one example, the registration pen is in the form of a rectangular parallelepiped as a whole, but a pen tip is provided on its side, and a first identification pattern is provided on the side adjacent to the side with the pen tip (e.g., the side with the largest area). The number of pen tips can be 1, 2 or more. Providing a larger number of pen tips is convenient for replacement during later use. Of course, the embodiments of the present invention do not limit the specific forms of the registration pen and the registration plate.

[0111] In an embodiment of the registration plate, the number of first marking points on the registration plate is the same as the number of second marking points on the positioning target, and the first marking points are arranged correspondingly to the second marking points. The number of marking points can be greater than or equal to 4 to facilitate accurate registration.

[0112] In S3, the registration method further includes determining second transformation data between the position coordinates of at least one first marker in the first recognition pattern coordinate system and the position coordinates of at least one second marker in the positioning target coordinate system. The position of the first marker in the first recognition pattern coordinate system and the position of the second marker in the positioning target coordinate system are known information, and thus the second transformation data can be determined based on this known information. The second transformation data can be a second transformation matrix Z2.

[0113] For example, the positions of the first marking point and the second marking point can be made to correspond one to one, and the first recognition pattern coordinate system is the same as the positioning target coordinate system. Then the coordinates of the first marking point under the first recognition pattern coordinates are the coordinates of the corresponding second marking point under the positioning target coordinates, and the second conversion data is the second conversion matrix (for example, the unit matrix).

[0114] In S31 , aligning the first marking points of the registration tool with the second marking points of the positioning target includes: placing the registration tool on the positioning target, and aligning each first marking point with each corresponding second marking point.

[0115] In one example, the first and second marking points are configured as matching concave and convex points, respectively, to facilitate mounting the registration tool on the positioning target. In the example of a registration plate, the first marking point of the registration plate is located on a side surface of the registration plate adjacent to the side surface provided with the first recognition pattern. Of course, the embodiments of the present invention do not limit the specific form of the first and second marking points, and those skilled in the art may configure them as needed.

[0116] In S31, when the registration device is set on the positioning target, the image data when the first mark point and the second mark point are aligned (image data of the positioning device and the registration plate) is obtained through the camera, and the posture matrix of the first recognition pattern and the posture matrix of the second recognition pattern are obtained based on the image data.

[0117] In S32, as Figure 3 As shown, converting the spatial data of the first marking point into spatial data in the second recognition pattern coordinate system of the positioning device includes:

[0118] S321 determines the position coordinates of the at least one first marking point in the camera coordinate system using the position coordinates of the at least one first marking point in the first recognition pattern coordinate system and the posture matrix of the first recognition pattern;

[0119] S322 determines the position coordinates of at least one second marking point in the second recognition pattern coordinate system by using the position coordinates of at least one first marking point in the camera coordinate system, the posture matrix of the second recognition pattern, and the second conversion data.

[0120] The position coordinates of at least one first marking point in the first recognition pattern coordinate system are known. The pose matrix of the first recognition pattern and the pose matrix of the second recognition pattern are acquired via a camera. For example, when the positioning device and / or the positioning target are in motion, the camera acquires image data in real time to thereby obtain the pose matrix of the first recognition pattern and the pose matrix of the second recognition pattern.

[0121] In S322, the position coordinates of at least one second marker point corresponding to the at least one first marker point in the second recognition pattern coordinate system may be determined based on the position coordinates of the at least one first marker point in the camera coordinate system, the pose matrix of the second recognition pattern, and the second conversion data. The position coordinates of the at least one second marker point in the camera coordinate system may be determined based on the position coordinates of the at least one first marker point in the camera coordinate system and the second conversion data; and then the position coordinates of the at least one second marker point in the second recognition pattern coordinate system may be determined based on the position coordinates of the at least one second marker point in the camera coordinate system and the pose matrix of the second recognition pattern.

[0122] In S33, determining first transformation data between the spatial data of the positioning target and the spatial data of the positioning device includes: determining the first transformation data using the position coordinates of at least one second marker point in the second recognition pattern coordinate system and the position coordinates of at least one second marker point in the positioning target coordinate system. For example, the position coordinates of the second marker point in the second recognition pattern coordinate system and the position coordinates of the second marker point in the positioning target coordinate system may be formed into a data pair, and the first transformation data may be determined using methods such as singular value decomposition (SVD), point cloud registration (ICP), and quaternion.

[0123] For example, the number of first marking points on the registration plate is n, and the position coordinates of the first marking points in the first recognition pattern coordinate system are W1, W2, ..., W n The number of the second marking points is also n, and the position coordinates of the second marking points in the positioning target coordinate system are P1, P2...P n The posture matrix of the first recognition pattern is Z3, and the posture matrix of the second recognition pattern is Z4. Using the position coordinates W1, W2, ... W of the first marking point n The position coordinates Q1, Q2, ... Q of the first marking point in the camera coordinate system are determined by the posture matrix Z3 of the first recognition pattern. n Using the position coordinates Q1, Q2, ... Q of the first marking point n The position coordinates R1, R2, ... R of the corresponding second marker point in the camera coordinate system are determined by the second conversion data Z2. n Using the position coordinates of the second marking point R1, R2, ... R n The position coordinates S1, S2, ... S of the second marking point in the second recognition pattern coordinate system are determined by the posture matrix Z4 of the second recognition pattern. n Using the position coordinates S1, S2, ... S of the second marking point n and the position coordinates of the second marking point P1, P2...P n Construct data pairs (S1, P1), (S2, P2) ... (S n , P n ), and determine the first transformation matrix Z1 through a known algorithm.

[0124] In the embodiment using a registration plate, the registration process requires mounting the registration plate on the positioning target, collecting the posture matrix of the recognition pattern, and completing the registration process based on the known information. This process is relatively simple and has high efficiency.

[0125] In an embodiment of the registration pen, the spatial data of the first marking point includes the position coordinates of the pen tip in the first recognition pattern coordinate system, and the second marking point includes at least one second marking point. The number of the second marking points can be greater than or equal to 4 to facilitate accurate registration.

[0126] In S31, aligning the first marking point of the registration tool with the second marking point of the positioning target includes: placing the tip of the registration pen at all the second marking points of at least one second marking point.

[0127] In S31, when the tip of the registration pen is placed at one of the at least one second marking points, image data of the positioning device and the registration pen is obtained through a camera, and a posture matrix of the first recognition pattern and a posture matrix of the second recognition pattern are obtained based on the image data.

[0128] In S32, converting the spatial data of the first marking point into spatial data in the second recognition pattern coordinate system of the positioning device includes:

[0129] When the pen tip is placed at one of the at least one second marking points,

[0130] Determine the position coordinates of the pen tip in the camera coordinate system using the position coordinates of the pen tip in the first recognition pattern coordinate system and the posture matrix of the first recognition pattern acquired by the camera when the pen tip is placed at the one second marking point;

[0131] Determine the position coordinates of the pen tip in the second recognition pattern coordinate system using the position coordinates of the pen tip in the camera coordinate system and the posture matrix of the second recognition pattern acquired by the camera when the pen tip is placed at the second marking point,

[0132] When the pen tip is placed at another second marking point among the at least one second marking point, the above process is repeated until the position coordinates of the pen tip in the second recognition pattern coordinate system are determined when the pen tip is located at all the second marking points.

[0133] That is, in an embodiment using a registration pen, the registration pen (specifically the pen tip) needs to be placed on all the second marking points in turn, and when placed on a second marking point, the posture matrix of the first recognition pattern and the second recognition pattern at this time is obtained using the camera, until the posture matrix of the first recognition pattern and the second recognition pattern when located at all second marking points is obtained, and the posture matrix of the first recognition pattern and the second recognition pattern when located at a second marking point is used to determine the position coordinates of the pen tip when it is located at the second marking point in the second recognition pattern coordinate system, until the position coordinates of the pen tip when it is located at all second marking points in the second recognition pattern coordinate system are determined.

[0134] In S33, determining the first conversion data between the spatial data of the positioning target and the spatial data of the positioning device includes: using the position coordinates of the pen tip in the positioning target coordinate system when the pen tip is located at all second marking points and the position coordinates of the pen tip in the second recognition pattern coordinate system when the pen tip is located at all second marking points to determine the first conversion data. The position coordinates of the pen tip in the positioning target coordinate system when the pen tip is located at all second marking points are the position coordinates of the second marking points in the positioning target coordinate system, and this data is known information. The first conversion data can be determined using methods such as singular value decomposition (SVD), point cloud registration (ICP), and quaternion.

[0135] For example, the position coordinate of the pen tip of the registration pen in the first recognition pattern coordinate system is W'. The number of second marking points is n, and the position coordinates of the second marking points in the positioning target coordinate system are P1, P2...P n , then the position coordinates of the pen tip when it is located at all the second marking points in the positioning target coordinate system are P1, P2...P n The posture matrices of the first recognition pattern obtained when the pen tip is located at the second marking point are Z 31 , Z 32 , ... Z 3n , the corresponding posture matrix of the second recognition pattern is Z 41 , Z 42 , ... Z 4n Using the position coordinates W' of the pen tip and the posture matrix Z of the first recognition pattern when the pen tip is at a second marking point P1 31 , determine the position coordinate Q1' of the pen tip in the camera coordinate system. Use the position coordinate Q1' of the pen tip and the posture matrix Z of the second recognition pattern when the pen tip is at the second mark point P1 41 , determine the position coordinate S1' of the pen tip in the second recognition pattern coordinate system when the pen tip is at the second mark point P1. Repeat the above steps using the posture matrix of the first recognition pattern at other second mark points P1, etc., until the position coordinates S1', S2'...S of the pen tip in the second recognition pattern coordinate system when the pen tip is at all second mark points are obtained. n '. Use the position coordinates S1', S2'...S of the pen tip in the second recognition pattern coordinate system when the pen tip is at all the second marking points n ' and the position coordinates of the pen tip when it is at the second mark point P1, P2...P n Constructing data pairs (S1', P1), (S2', P2)... (S n ', P n ), and determine the first transformation matrix Z1' through a known algorithm.

[0136] Embodiments of the present invention can provide different registration tools for different positioning targets, increasing the flexibility of the registration method. For example, if the positioning target is not flat or has a regular curved surface (such as a sphere), it is not convenient to install a registration plate, so a registration pen can be used for registration. If the positioning target has a flat or regular curved surface, using a registration plate for registration can avoid the need to click different second marking points with a registration pen, simplifying the operation process and improving work efficiency.

[0137] In one example, a registration tool is an auxiliary tool that has no material restrictions and can be machined from metal. This allows for the use of metal materials in manufacturing, eliminating the problem of poor precision caused by plastic processing, for example, its precision can be less than a thread.

[0138] In the embodiment of the present invention, in order to improve registration efficiency, batch registration can be implemented, that is, the registration of multiple positioning targets and positioning devices can be completed in the same image.

[0139] Specifically, if Figure 4 As shown, in S31, the registration method further includes:

[0140] S311 determines a first reference area surrounding the first recognition pattern of the registration tool and the second recognition pattern of the positioning device, and determines a size relationship among the first recognition pattern, the second recognition pattern, and the first reference area;

[0141] S312: recognizing an identification pattern in image data obtained by a camera when the first marking point and the second marking point are aligned, wherein the identification pattern is a second identification pattern of a positioning device or a first identification pattern of a registered tool;

[0142] S313 determines the pixel size and pixel position of the identified recognition pattern in the image data;

[0143] S314 determining a second reference area corresponding to the first reference area in the image data based on the pixel size, pixel position, and the size relationship;

[0144] S315 acquiring, in the second reference area, spatial data of the first recognition pattern and spatial data of the second recognition pattern when the first marking point is aligned with the second marking point;

[0145] S316 removes the portion corresponding to the first reference area from the image data, or removes the portion corresponding to the first reference area and the portion corresponding to the second reference area, and repeats the above operation until all recognition patterns in the image data are recognized.

[0146] In S311, the shape of the first reference area can be a rectangle, square, circle, trapezoid, etc. The embodiments of the present invention do not limit its specific shape, and those skilled in the art can select it as needed. The construction of the first reference area is known in advance, so the dimensional relationship is also known. The dimensional relationship includes the ratio of the size of each pattern to the size of the first reference area, the position of each pattern in the first reference area, etc.

[0147] In S312, the camera may acquire image data when the first marking point and the second marking point are aligned. The pattern information of the first recognition pattern and the second recognition pattern is known, so a recognition pattern (the first recognition pattern or the second recognition pattern) may be recognized from the image data using a known algorithm.

[0148] In S313 , when a recognition pattern is recognized in the image data, the pixel size and pixel position of the recognition pattern in the image data may be determined.

[0149] In S314, a second reference region corresponding to the first reference region is determined in the image data based on the pixel size and pixel position determined in S313 and the size relationship determined in S311. For example, the second reference region may be determined around the identified recognition pattern based on the size relationship. Of course, the second reference region may also be determined around the identified recognition pattern at a reduced or larger scale based on the size relationship.

[0150] Since the second reference area corresponds to the first reference area, the second reference area includes not only the recognized recognition pattern but also the recognition pattern of the positioning device or the registration tool. Therefore, in S315, the spatial data of the corresponding first recognition pattern and the second recognition pattern can be obtained.

[0151] In S316, the portion corresponding to the first reference area is removed from the image data, or the portion corresponding to the first reference area and the portion corresponding to the second reference area are removed (for example, the portion can be filled with a white area), and the above operation is repeated until all recognition patterns in the image data are identified.

[0152] For example, when the recognition pattern identified in S312 is the second recognition pattern of a positioning device, after determining the second reference area, the first recognition pattern of the registration tooling corresponding to the positioning device is identified in the second reference area (S315), and based on the identified first recognition pattern and the second recognition pattern, the spatial data of the first recognition pattern and the spatial data of the second recognition pattern when the first mark point is aligned with the second mark point are obtained; or, when the recognition pattern identified in S312 is the first recognition pattern of a registration tooling, after determining the second reference area, the second recognition pattern of the positioning device corresponding to the registration tooling is identified in the second reference area (S315), and based on the identified first recognition pattern and the second recognition pattern, the spatial data of the first recognition pattern and the spatial data of the second recognition pattern when the first mark point is aligned with the second mark point are obtained.

[0153] In one example, among the positioning targets registered in batches, the second recognition pattern of each positioning target is different from the first recognition pattern of its corresponding registration tool, so as to accurately form the second reference area.

[0154] In one example, the batch registration process of the present invention is applicable to the case where the second recognition pattern of each positioning target is the same, and may also be applicable to the case where the second recognition pattern of each positioning target is not the same.

[0155] In the registration method of the embodiment of the present invention, the distance between the camera and the positioning target is determined based on the smaller pattern of the first recognition pattern and the second recognition pattern, and the focal length of the camera, so as to improve registration accuracy.

[0156] In an embodiment of the present invention, a registration component is provided. Figure 5 As shown, the registration component 100 includes a registration tool 10 , a camera 20 , a recognition module 30 and a control module 40 .

[0158] The camera 20 is configured to acquire image data.

[0159] The recognition module 30 is in communication with the camera 20. The recognition module 30 is configured to obtain spatial data of the first recognition pattern and spatial data of the second recognition pattern of the positioning target from the image data. The recognition module 30 can use the method described in the above embodiment to recognize the spatial data of the first recognition pattern and the second recognition pattern.

[0160] The control module 40 is communicatively coupled to the recognition module 30. The control module 40 is configured to determine first conversion data between the spatial data of the positioning target and the spatial data of the positioning device using the spatial data of the first recognition pattern and the spatial data of the second recognition pattern, as well as the spatial data of the first marking point and the spatial data of the second marking point from the recognition module 30. The control module 40 may determine the first conversion data using the method described in the aforementioned embodiment.

[0161] In one example, the camera 20 is configured to acquire image data when a first marking point of the registration tool 10 is aligned with a second marking point of the positioning target. Detailed description of the camera 20 can be found in the aforementioned embodiment and will not be repeated here.

[0162] In one example, the recognition module 30 is configured to obtain, from the image data, spatial data of a first recognition pattern when the first marking point is aligned with the second marking point and spatial data of a second recognition pattern of the positioning target. The recognition module 30 can use the method described in the above embodiments to recognize the spatial data of the first recognition pattern and the second recognition pattern.

[0163] In one example, the control module 40 is configured to convert the spatial data of the first marking point into spatial data in the second recognition pattern coordinate system of the positioning device using the spatial data of the first recognition pattern and the spatial data of the second recognition pattern from the recognition module 30, and determine first conversion data between the spatial data of the positioning target and the spatial data of the positioning device based on the spatial data in the second recognition pattern coordinate system and the spatial data of the second marking point. The control module 40 may determine the first conversion data using the method described in the aforementioned embodiment.

[0164] In one example, the recognition module 30 is further configured to: identify an identification pattern in image data obtained by a camera when a first marking point and a second marking point are aligned, the identification pattern being a second identification pattern of a positioning device or a first identification pattern of a registered tool; determine the pixel size and pixel position of the identified identification pattern in the image data; determine a second reference area corresponding to the first reference area in the image data based on the pixel size, pixel position, and the size relationship between the first identification pattern, the second identification pattern, and the first reference area, the first reference area being an area surrounding the first identification pattern of the registered tool and the second identification pattern of the positioning device; obtain spatial data of the first identification pattern and spatial data of the second identification pattern when the first marking point and the second marking point are aligned in the second reference area; remove the portion corresponding to the first reference area from the image data, or remove the portion corresponding to the first reference area and the portion corresponding to the second reference area, and repeat the above operations until all identification patterns in the image data are identified. The recognition module 30 can identify all identification patterns in the image data using the method described in the aforementioned embodiment.
