Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

As shown in fig. 1, the wiring board image display apparatus may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of a wiring board image display device, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a board image display program.
In the wiring board image display apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the circuit board image display apparatus according to the present invention may be provided in a circuit board image display apparatus that calls a circuit board image display program stored in the memory 1005 by the processor 1001 and executes the circuit board image display method provided by the embodiment of the present invention.
An embodiment of the present invention provides a method for displaying an image of a circuit board, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of the method for displaying an image of a circuit board according to the present invention.
In this embodiment, the circuit board image display method includes the following steps:
step S10: and when a circuit board image viewing instruction input by a user is received, acquiring a circuit board image to be loaded.
It should be noted that the execution subject of the present embodiment is a terminal device, such as a computer, an intelligent mobile terminal, and the like. The terminal equipment comprises a background and a front end, wherein the background is used for acquiring circuit board images from the data server, and the front end is used for displaying the circuit board images.
It can be understood that, when a user needs to view pictures, the user acquires the pictures from the data server in real time, but when the network bandwidth is low, the viewing experience of the user is affected by loading the pictures, and because the circuit board is fine and complicated, the part needing to be checked in the circuit board image needs to be enlarged and viewed, the circuit board image is loaded in real time, and then the checking efficiency of the circuit board is seriously affected by the user automatically enlarging the image.
In this embodiment, when a circuit board image viewing instruction input by a user is received, an image of a circuit board to be loaded is obtained from a data server in advance, and since the user usually checks according to the serial number sequence of the circuit board, the next image of the circuit board image that the user has last viewed (i.e., the image of the circuit board to be loaded) is directly obtained.
Further, the acquiring an image of the circuit board to be loaded includes: determining the checked circuit board image; and acquiring a first circuit board image to be loaded, a second circuit board image to be loaded and a third circuit board image to be loaded according to the checked circuit board image.
It should be noted that the viewed circuit board image refers to a circuit board image that has been viewed by a user last time, a number of the viewed circuit board image is determined, and three circuit board images after the number are obtained, that is, a first circuit board image to be loaded, a second circuit board image to be loaded, and a third circuit board image to be loaded.
Meanwhile, three circuit board images are loaded in advance, so that the phenomenon that the checking speed is higher than the loading speed due to the fact that the user checks the circuit board images too fast can be effectively avoided, and further the checking efficiency of the circuit board images is reduced.
Step S20: and determining a local amplified image of the circuit board image to be loaded based on the historical viewing record of the user, and loading the circuit board image to be loaded and the local amplified image into a global variable.
It should be noted that the history viewing record includes what portions of the viewed circuit board image are magnified by the user, and what resolution of the magnified image is. For example, the user zooms in on some portion of the historical view wiring board image to a 300 x 300 pixel image or a 400 x 600 pixel image. The part of the wiring board to be loaded is enlarged to 300 × 300 pixels or 400 × 600 pixels, thereby obtaining a partially enlarged image. The local magnified image includes the defective portion of the circuit board in the circuit board image to be loaded, and different circuit boards have different defects, so the local magnified image has different numbers according to the size of the circuit board image to be loaded. For example, the image of the circuit board to be loaded may have 50 partial enlarged images.
After the local amplified images of the first to-be-loaded circuit board image, the second to-be-loaded circuit board image and the third to-be-loaded circuit board image are obtained, the to-be-loaded circuit board image and the local amplified images are stored into a global variable, and the global variable is stored in a memory of the terminal equipment, so that the front end can conveniently and rapidly read and display the to-be-loaded circuit board image and the local amplified images. As shown in fig. 3, NG1 is a first to-be-loaded circuit board image, 50 local enlarged images are provided in total, NG2 is a second to-be-loaded circuit board image, 70 local enlarged images are provided in total, NG3 is a third to-be-loaded circuit board image, 30 local enlarged images are provided in total, the first to-be-loaded circuit board image, the second to-be-loaded circuit board image and the local enlarged images of the third to-be-loaded circuit board image are not all stored in a global variable, and the first 30 local enlarged images of the first to-be-loaded circuit board image, the first 20 local enlarged images of the second to-be-loaded circuit board image and the first 20 local enlarged images of the third to-be-loaded circuit board image are stored in the global variable.
Step S30: and when receiving a board cutting operation instruction input by the user, determining a target circuit board image according to the board cutting operation instruction.
It can be understood that, the board cutting operation instruction is used for switching the circuit board image being viewed, and the front-end interface includes: "next page local enlarged image", "next circuit board image", "input circuit board number to be checked", and the like. Since a large number of partial enlarged images can be displayed at the same time, a plurality of partial enlarged images can be displayed in the same page, and when all the partial enlarged images cannot be displayed in the same page, the partial enlarged images are divided into a plurality of pages to be displayed. When a user clicks the 'next local enlarged image', the circuit board image cannot be switched on the front-end page, and only the next local enlarged image of the circuit board image is switched. When the user clicks the next circuit board image, the fact that the user inputs the board cutting operation instruction is judged, the next circuit board image needs to be switched to, and the next circuit board image is the target circuit board image. When the user clicks 'input of the circuit board number to be checked', the user can be supported not to check the image according to the circuit board number, and after the user inputs the determined circuit board number in the input box, the target circuit board image is determined according to the circuit board number.
Step S40: and when the target circuit board image is the circuit board image to be loaded in the global variable, displaying a local amplification image of the circuit board image to be loaded.
It should be noted that, the circuit board number of the target circuit board image is matched with the circuit board number of the circuit board image to be loaded in the global variable, and when the matching is successful, the front end loads the corresponding circuit board image to be loaded from the global variable and displays the locally amplified image of the circuit board image to be loaded.
Further, after determining the target circuit board image according to the board cutting operation instruction when receiving the board cutting operation instruction input by the user, the method further includes: deleting the circuit board image to be loaded in the global variable when the target circuit board image is not the circuit board image to be loaded in the global variable; acquiring the target circuit board image; acquiring a target circuit board image to be loaded according to the target circuit board image; and loading the local amplified image of the target circuit board image to be loaded into the global variable.
In the specific implementation, when the target circuit board image and the corresponding local amplified image are not stored in the global variable, the circuit board image to be loaded and the corresponding local amplified image in the global variable are deleted immediately, the circuit board image (namely the target circuit board image to be loaded) is downloaded immediately from the data server, the local amplified image of the target circuit board image to be loaded is generated after the downloading is completed, the local amplified image of the target circuit board image to be loaded and the target circuit board image to be loaded are stored in the global variable, and the local amplified image and the target circuit board image to be loaded are read from the global variable and displayed at the front end.
Similarly, the front end can also directly download the target circuit board image to be loaded from the data server, and the user can automatically amplify the image for viewing, so that a background is not needed to generate a local enlarged image, and the checking efficiency of the user can be improved.
It can be understood that, as shown in fig. 4, the haveredboard is a global variable, when the circuit board image needs to be checked, whether the circuit board image and the locally amplified image exist in the haveredboard is detected, when the circuit board image exists, the ith part of the circuit board image is read, when a user has a board cutting operation, whether the circuit board image needing to be switched is stored in the haveredboard is judged, and when the circuit board image does not exist in the haveredboard, the corresponding circuit board image is searched and stored in the haveredboard.
In the embodiment, when a circuit board image viewing instruction input by a user is received, a circuit board image to be loaded is obtained; determining a local amplified image of the circuit board image to be loaded based on a historical viewing record of a user, and loading the circuit board image to be loaded and the local amplified image to a global variable; when a board cutting operation instruction input by a user is received, determining a target circuit board image according to the board cutting operation instruction; and when the target circuit board image is the circuit board image to be loaded in the global variable, displaying the corresponding local amplified image. By the method, the circuit board image and the local enlarged image are loaded into the global variable in advance, and when the circuit board image needs to be displayed, the circuit board image and the local enlarged image are directly read from the global variable and displayed, so that the loading time is shortened, and the efficiency of checking the circuit board image is improved.
Referring to fig. 5, fig. 5 is a schematic flow chart of a circuit board image display method according to a second embodiment of the present invention.
Based on the first embodiment, in step S20, the method for displaying images on a circuit board according to this embodiment includes:
step S21: and determining a plurality of historical local enlarged images corresponding to the historical circuit board images according to the historical viewing records.
In a specific implementation, the historical circuit board image refers to a circuit board image that has been viewed by a user, and when the user does not view any circuit board image, a local enlarged image is not generated, and the circuit board image is automatically enlarged by the user. When the user amplifies the circuit board image by himself, the terminal device records the resolution of the circuit board image when the user amplifies the circuit board image, and records the image (namely, the historical partial amplification) when the circuit board image is viewed and the data such as viewing time.
Step S22: and determining the viewing time length of each historical local magnified image.
It can be understood that the viewing duration of each history local enlarged image is recorded in the history viewing record, and the viewing duration may be 5 seconds, 10 seconds, and the like, which is not limited in this embodiment.
Step S23: and determining the target local resolution according to the viewing time.
It should be noted that the history local magnified image whose viewing time has passed the preset time is selected, and the preset time may be 10 seconds or 15 seconds. And taking the historical local enlarged image with the viewing time length exceeding the preset time length as a target historical local enlarged image, acquiring the resolution of the target historical local enlarged image, and calculating the average value of the resolutions of a plurality of target historical local enlarged images when the target historical local enlarged images are multiple, thereby obtaining the target local resolution.
Step S24: and determining a local amplified image of the circuit board image to be loaded according to the target local resolution and each historical local amplified image, and loading the circuit board image to be loaded and the local amplified image into a global variable.
Further, the determining the local enlarged image of the to-be-loaded circuit board image according to the target local resolution and the historical local enlarged images includes: dividing the circuit board image to be loaded into a plurality of local amplified images to be selected, wherein the local amplified images have the resolution consistent with the target local resolution; determining the maximum similarity matching degree between each local amplified image to be selected and each historical local amplified image; and selecting a local amplified image from the local amplified images to be selected according to the maximum similarity matching degree.
It should be noted that, because the defective position of the circuit board to be loaded is already marked, the marked pixel is taken as a central point, and a defective position image within a preset range is selected, and a plurality of defective positions may exist on the circuit board to be loaded. For example, the marked pixel coordinate is (1000 ), the predetermined range is 800 × 800, and the defective position image has the pixel coordinates of (200 ), (200, 1800), (1800, 200), (1800 ). The above are merely examples, and the present embodiment is not limited thereto.
In a specific implementation, after obtaining the image of the incomplete position, based on the target local resolution, the image of the incomplete position is divided into a plurality of local enlarged images to be selected, for example: the resolution of the image at the incomplete position is 800 × 800, the target local resolution is 400 × 400, if the local enlarged image to be selected does not have a superposed image, the image can be divided into 4 local enlarged images to be selected, and if the superposed part exists, the image can be divided into more than 4 local enlarged images to be selected.
It will be appreciated that the defective portions on the circuit board are generally for several of the same reasons, for example: prevent welding hole foreign matter, metal hole foreign matter, etc. Therefore, the incomplete position on the local amplified image to be selected has certain similarity with the incomplete position on the historical local amplified image, and therefore the local amplified image to be selected which possibly has a similarity problem can be selected by determining the maximum similarity matching degree between each local amplified image to be selected and each historical local amplified image.
Further, the determining the maximum similarity matching degree between each local enlarged image to be selected and each historical local enlarged image includes: graying each history local amplified image to obtain each gray history local amplified image, and graying each local amplified image to be selected to obtain each gray local amplified image to be selected; normalizing each gray scale history local enlarged image into each normalized gray scale history local enlarged image with a preset size, and normalizing each gray scale candidate local enlarged image into each normalized gray scale candidate local enlarged image with the preset size; matching each normalized gray scale historical local amplified image with each normalized gray scale local amplified image to be selected to obtain a similarity matching degree set of each normalized gray scale local amplified image to be selected; and selecting the maximum similarity matching degree from the similarity matching degree set.
In this embodiment, graying means that each pixel in the pixel matrix satisfies the following relationship: r = G = B (i.e. the value of the red variable, the value of the green variable, and the value of the blue variable, which are equal), and this value is called the gray value. Normalization refers to unifying the resolution of images into one resolution. However, since the resolution of the local enlarged image to be selected is substantially the same as that of the historical local enlarged image, this step is only to prevent the presence of images with different resolutions.
It can be understood that the local enlarged image of the history of the first gray scale is set to be { x1, x2, x3... xn }, the local enlarged image to be selected of the first gray scale is set to be { y1, y2, y3... yn }, the similarity matching degrees are respectively calculated for y1 and { x1, x2, x3... xn }, a similarity matching degree set of y1 is obtained, and the similarity matching degrees are respectively calculated for y2 to yn and { x1, x2, x3... xn }, so that a similarity matching degree set of y2 to yn is obtained.
Therefore, the selected maximum similarity matching degree in the similarity matching degree set of the to-be-selected local enlarged images of the normalization gray scale is obtained, and each to-be-selected local enlarged image of the normalization gray scale has the corresponding maximum similarity matching degree.
Further, the selecting a local enlarged image from each to-be-selected local enlarged image according to the maximum similarity matching degree includes: sorting the local amplified images to be selected according to the maximum similarity matching degree; and selecting a local enlarged image from the sorted local enlarged images to be selected.
The local enlarged images to be selected are sorted according to the maximum similarity matching degree from large to small, and a preset number of the local enlarged images to be selected are selected as the local enlarged images, where the preset number may be 50, 60, 70, and the like, and this embodiment is not limited.
The embodiment determines a plurality of historical partial enlarged images corresponding to the historical circuit board images according to the historical viewing records; determining the viewing time of each historical local amplified image; determining a target local resolution according to the viewing duration; and determining the local amplified image of the circuit board image to be loaded according to the target local resolution and each historical local amplified image. By means of the mode, the habitual resolution ratio of the user in the process of viewing the image is determined based on the historical viewing record of the user, so that the local enlarged image is determined in the circuit board image to be loaded, and the user experience is further improved.
In addition, an embodiment of the present invention further provides a storage medium, where the storage medium stores a circuit board image display program, and the circuit board image display program, when executed by a processor, implements the steps of the circuit board image display method as described above.
Since the storage medium adopts all technical solutions of all the embodiments, at least all the beneficial effects brought by the technical solutions of the embodiments are achieved, and no further description is given here.
Referring to fig. 6, fig. 6 is a block diagram of the first embodiment of the circuit board image display device of the present invention.
