Referring to fig. 1, the present invention provides a code reading method, which is applied to an electronic device 10 communicatively connected to a camera device 20, for reading a mark on a workpiece photographed by the camera device 10. The electronic device 10 may be a production machine or a computer device. The camera device 20 may be an industrial camera. The code reading method comprises the following steps.
Step S101: and providing a user verification interface according to the response operation and verifying whether the user is a legal user or not according to the information input in the user verification interface.
Step S102: and when the user is a legal user, providing a human-computer interaction interface for the user to select the identification type, wherein the identification type comprises a two-dimensional code identification and a CNC dot matrix code identification. In an embodiment, the step S101 may not be included, and the human-machine interaction interface is directly provided.
Step S103: a workpiece image captured by the camera 20 is acquired, the workpiece image including a logo.
Step S104: and confirming the identification type selected by the user according to the operation of the user on the man-machine interaction interface.
Step S105: and identifying the two-dimensional code mark on the obtained industrial image according to a first image processing method or identifying the CNC dot matrix code mark on the obtained industrial image according to a second image processing method.
In an embodiment, the human-computer interaction interface is further configured to set basic information of the image reference parameter and the identifier. The basic information of the mark includes, but is not limited to, the position and size of the mark to be located on the workpiece. In an embodiment, the basic information of the identifier is obtained by loading a text file, and the text file is stored in a preset address. In another embodiment, the identified basic information is set through an input box displayed on the human-computer interaction interface. The image reference parameters include the spacing between marker points in the markers. In the two-dimensional code identification, the mark points refer to pixel points in the two-dimensional code identification. In the CNC dot matrix code identification, the mark points refer to sunken points in the CNC dot matrix code, and the CNC dot matrix code identification is formed by a plurality of sunken points processed through CNC.
In step S105, identification recognition on the industrial image is performed by applying the first image processing method or the second image processing method according to the image reference parameter and the basic information of the identification set on the human-computer interaction interface. In one embodiment, the valid users include a general user and an administrative user, and whether the user is the general user or the administrative user is verified according to information input by the user verification interface. When the verification user is a management user, the human-computer interaction interface allows the setting of the basic information of the image reference parameters and the identification, and when the verification user is a general user, the human-computer interaction interface does not allow the setting of the basic information of the image reference parameters and the identification, but displays the default basic information of the image reference parameters and the identification.
Specifically, when the confirmed identification type is the two-dimensional code identification, a figure limited area on the acquired workpiece image is determined according to the position and the size of the two-dimensional code identification on the workpiece, the determined figure limited area is subjected to image processing to determine the minimum value and the maximum value range of matrix points and the maximum value and the minimum value range of the intervals between the matrix points in the figure limited area, and the size of black and white pixel points and the intervals between the pixel points in the matrix space are determined through a figure pixel proportion coefficient. And finally, processing by adopting an international universal coding and decoding principle, and extracting the information in the image limited area to obtain the composition information of the two-dimensional code identifier. In addition, the appearance color of the workpiece can brighten or darken the graphic background of the two-dimensional code identification, the appearance color of the workpiece can be set on a human-computer interaction interface, and the background in the workpiece image is subjected to denoising processing before the identification through reading the appearance color information of the workpiece, so that the identification accuracy of the two-dimensional code identification is improved.
When the confirmed identification type is the CNC dot matrix code identification, determining a figure limited area on the acquired workpiece image according to the position and the size of the CNC dot matrix code identification on the workpiece, carrying out image processing on the determined figure limited area to determine the range of the minimum value and the maximum value of matrix points and the range of the maximum value and the minimum value of the space between the matrix points in the figure limited area, and determining the size of the matrix points and the space between the matrix points through the figure pixel proportionality coefficient. Then, according to the dotting direction in the CNC process, carrying out direction sequencing on the CNC dot matrix codes (for example, a mode that 3 rows and 11 columns carry out direction sequencing from right to left and from top to bottom), and presetting the maximum image scaling and the minimum image scaling, and identifying the marking points of the industrial image. Then, similarity judgment is carried out on the identified images of the marking points according to parameters such as point outlines, shapes, sizes and the like. If the similarity value is larger than the set value, the mark point is confirmed to be an effective point, and the coordinate position information of the effective point is recorded. And finally, compiling the identified effective points according to the encoding principle of the lattice structure, and analyzing the composition information of the CNC lattice code identifier, such as the composition information consisting of coordinates [0,5], [1,0], [1,2], [1,4], [1,9], [2,0], [2,1], [2,3] and [2,9 ].
Step S106: displaying information of the identified logo.
Step S107: storing an identification record to a predetermined address, the identification record including information of the identified identification. In one embodiment, the predetermined address is set by a path setting operation on the human-computer interaction interface. In another embodiment, the predetermined address is a default address. The predetermined address may be an address in the electronic device or an address in a server communicatively connected to the electronic device. The mark record can also comprise workpiece information and standard information of the mark, wherein the workpiece information comprises the name of the workpiece and the manufacturing process of the mark, such as assembly, sand blasting, station milling and the like, and the standard information comprises a standard position and a standard size which the mark should have.
