The graphical interface module 150 is used to provide a graphical interface for the user to interact with the system 1000 through the graphical interface and automatically determine the correctness of the component. For example, the system 1000 is configured to automatically determine the correctness of the component through the graphical interface and to view the results of the recognition.

The steps of the method for automatically determining the correctness of the parts of the present embodiment will be described below with the system 1000 for automatically determining the correctness of the parts. 2 is a flow chart of a method for automatically determining the correctness of a part according to an embodiment of the invention. FIG. 3 is a schematic diagram of a graphical interface according to an embodiment of the invention. Referring to FIG. 1 , FIG. 2 and FIG. 3 simultaneously, in this embodiment, in step S210, the standard part database is established by the database establishing module 140. In detail, after the standard motherboard is placed on the special fixture (not shown) of the system 1000 for automatically determining the correctness of the component, the image capture device 120 can capture a complete image of the standard motherboard of the standard motherboard. And through the graphical interface 300 provided by the graphical interface module 150 to display a complete image of the standard motherboard. In particular, the graphical interface 300 provides a plurality of circle selection functions, such as a square or elliptical circle selection function. Therefore, in the process of creating a standard part image, the graphical interface module 150 can receive the user's use of the circle selection function. Multiple ranges of circled inputs are used to define specific areas of a standard part. That is, the user can circle a specific area in the complete image of the standard motherboard as a standard part image, and the library building module 140 is used to record the coordinate position of the specific area captured in the standard motherboard as a standard part. The location information of the image, and the user can set one of the part type information, the part shape information, and the part color information as a part attribute of the standard part image for the specific area captured. For example, the capacitive part properties on the host version have elliptical features, and depending on the polarity of the capacitor, the positive pole of the capacitor is shown in red and the negative pole is shown in green.

More specifically, as shown in the graphical interface 300 of FIG. 3, the user can view the complete image 37 of the standard motherboard captured by the image capturing device 120 in the window 370, and can utilize the system 1000 for automatically determining the correctness of the component. The configured input device (not shown) performs one or more range circle selection inputs. For example, when the user clicks the circle selection option 321 with the input device, the graphical interface 300 provides a square circle selection function, and the database creation module 140 will circle according to the range made by the user using the circle selection function. Enter to define a specific area. For example, if the user circled the square specific area 371a including the central processing unit 371, when the user presses the camera option 330, the database creating module 140 will extract the image of the specific area 371a and regard it as a standard. Part image. The user can set one of the part type information, the part shape information, and the part color information of the central processing unit 371, and the combination setting unit 140 stores the setting information input by the user as the corresponding central processing unit. Part properties for 371 standard part images. In addition, the database creation module 140 also records the coordinate position of the specific area 371a in the standard motherboard complete image 37 as the location information of the standard part image.

The user can also circle other parts on the full image 37 of the standard motherboard to produce more standard part images. In this embodiment, it is assumed that the user additionally circled the square specific area 372a including the central processing unit 372 and circled the elliptical specific areas 373a and 374a including the capacitor 373 and the capacitor 374. When the user presses the camera option 330, The database creation module 140 retrieves images of the particular regions 372a, 373a, and 374a and treats them as standard part images. As described above, the user can set the component attributes of the central processing unit 372, the capacitor 373 and the capacitor 374, and the database establishing module 140 stores the setting information input by the user as the corresponding central processing unit 372, the capacitor 373 and The component attributes of the standard part image of capacitor 374, as well as the coordinate position of the particular area 372a, 373a, and 374a in the full image 37 of the standard motherboard, are recorded as location information for this standard part image.

In more detail, after the user selects each specific area in the standard motherboard complete image 37 and inputs various settings, the standard motherboard image option 360 in the graphical interface 300 can be clicked to select the standard part image and the set. The data is stored in its entirety as information associated with this standard motherboard, and the above information can be displayed in the information bar 380 in the graphical interface 300. The information column 380 includes a part attribute field 381 and a location information field 382. In the present embodiment, the part attribute field 381 includes part number, part type information, and part shape information. In other embodiments, the part attribute field 381 may also include part color information. The location information field 382 includes the X-axis coordinates and the Y-axis coordinates of a certain identification point in a specific area, and the length and width of the specific area. For example, if a specific area is a square, the recognition point may be the upper left corner vertex of the specific area, and if the specific area is a circular type, the identification point may be the center point of the specific area.

In another embodiment, the user can also use the input device to select the load standard motherboard image option 350 in the graphical interface 300, so as to standardize the host that has been stored in a standard motherboard in the standard part database. The complete image of the board and related standard part images and their part attributes and position information are displayed on the graphical interface 300. The user can further circle and set new standard part images in the above manner. After you click the Save Standard Motherboard Image option 360, the new data will be saved in the standard parts library.

In other embodiments, graphical interface 300 may also provide an option to delete an existing standard part image, an option to adjust a standard motherboard full image 37 in window 370, and the like. It should be particularly noted that the graphical interface 300 is merely an example for convenience of explanation, and the present invention does not limit the appearance of the graphical interface 300 provided by the graphical interface module 150.

After the completion of the establishment of the standard parts database, if the test board to be tested is placed in the special fixture of the system 1000 for automatically determining the correctness of the parts, the image capturing device 120 shoots as shown in step S220 of FIG. The motherboard is tested to obtain a complete image of the tested motherboard.

Then, when the user clicks the comparison option 340 in the graphical interface 300, the system 1000 that automatically determines the correctness of the part begins the main process of determining the correctness of the part. As shown in step S230, the identification module 130 extracts the corresponding image of the part to be tested from the complete image of the tested main board according to the individual position information of the standard part image stored in the standard parts database.

Finally, in step S240, the identification module 130 obtains individual component attributes of each standard part image from the standard parts database, and analyzes the image of each part to be tested by using the individual part attributes of the standard part image to generate images of the parts to be tested. Whether the part configuration correctly identifies the result. In more detail, for each image of the part to be tested of the tested motherboard, the identification module 130 selects an appropriate picture matching rule according to the part attribute of the standard part image corresponding to the image of the part to be tested, and according to the picture ratio Whether the rule matches the image of the part to be tested and the corresponding standard part image. For example, when detecting a part image to be tested, if the part attribute of the corresponding standard part image shows that the part type of the standard part is a capacitor, the identification module 130 selects a picture that is advantageous for comparing the capacitance characteristics. Rules to detect. For example, since the capacitor has a specific shape and size, the identification module 130 will have an object having the same shape and size as the standard capacitance of the standard part image in the image of the part to be tested. If such an object exists, it means that the part in the image of the part to be tested may be a capacitor. In addition, since the two poles of the capacitor have different colors, the identification module 130 will further compare the color information of the object that may be a capacitor in the image of the part to be tested to determine whether the direction of the configuration matches the standard capacitance in the standard part image. If the comparison result shows that the image of the part to be tested matches the corresponding standard part image, the identification module 130 generates a correct recognition result of the part configuration in the image of the part to be tested. On the other hand, if the image of the part to be tested does not match the corresponding standard part image after the comparison, the identification module 130 may generate an identification result of the component configuration in the image of the part to be tested. In this embodiment, the identification module 130 stores the standard part image and the recognition result corresponding to the image of the part to be tested and the image of the part to be tested as a record file, so that the user can query the image of the part to be tested in the record file. Part properties and location information.

In addition, in the embodiment, the graphical interface module 150 provides a graphical interface 400 as shown in FIG. 4 to display the recognition result for the user to view. In detail, after the identification module 130 completes the analysis of the images of the parts to be tested, the graphical interface module 150 displays the complete image 47 of the tested motherboard on the window 470 of the graphical interface 400, and the parts in the information bar 480. The attribute field 481 and the position information field 482 list the part attribute and position information of each part image to be tested. The user can click on each of the parts to be tested in the information bar 480 to view the recognition result in the recognition result field 490, and simultaneously display the image of the part to be tested and the standard part image corresponding to each other in the image display field 410.

For example, if the image of the part to be tested, which is listed as part number 1 in the information field 480, includes the capacitor 473, the user can see the part attribute and position information of the capacitor 473 in the part attribute field 481 and the position information field 482. . If the user clicks on the data to generate the selection input, the recognition result of whether the capacitance 473 in the image of the part to be tested is correctly configured is displayed in the recognition result field 490. In the present embodiment, the display of "PASS" in the recognition result field 490 indicates that the image of the part to be tested including the capacitor 473 matches the corresponding standard part image in the standard part database, that is, the recognition result is that the part configuration is correct. At the same time, the user can view the standard part image 410a and the part image 410b to be tested displayed side by side in the image display field 410. In an embodiment, when the user clicks on a certain row of information in the information bar 480, a frame selection mark 473a is displayed on the complete image 47 of the tested motherboard to make it easier for the user to identify the part corresponding to the data. position.

However, as shown in FIG. 5, it is assumed that the image of the part to be tested which is listed as part number 2 in the information column 480 includes the capacitor 475, and the complete image of the tested motherboard is displayed when the user clicks the row of data to generate the selected input. A box selection mark 475a is displayed to allow the user to recognize the position of the part corresponding to the material. The graphical interface module 150 displays the recognition result generated by the recognition module 130 on the recognition result field 490 in the graphical interface 400. In this embodiment, the recognition result field 490 displays "FAIL" indicating that the image of the part to be tested including the capacitor 475 does not match the corresponding standard part image in the standard part database, that is, the recognition result is that the part configuration is incorrect. . The user can view the standard part image 415a recorded in the standard parts database in the image display field 410, and the image of the part to be tested 410b taken from the complete image 47 of the tested main board, thereby further judging according to the image. . If the user has doubts about the recognition result and wants to detect the capacitor 475 again, the user can click the re-alignment option 430 in the graphical interface 400. After receiving the input, the recognition module 130 will return to the standard part. The database obtains the standard part image 415a corresponding to the part image 410b to which the capacitor 475 belongs, and uses the part attribute of the standard part image 415a to determine whether the part image 410b to be tested matches the standard part image 415a, and the recognition result It will also be displayed in the recognition result field 490.

In addition, the user can also click on the log file option 430 in the graphical interface 400 to call out the log file containing the recognition result. By means of this record file, the user can completely view the recognition result of all the parts to be tested, and can also view the image of each part to be tested and the corresponding standard part image in the record file.

In the foregoing embodiment, since the identification module 130 compares the image of the part to be tested and the corresponding standard part image when detecting the part to be tested, the integrity of the tested motherboard and the standard motherboard is not required. The image scans and judges the entire image, so it is possible to reduce the time taken to compare the entire complete image by performing comparison analysis for a specific area, thereby greatly improving the efficiency of automatically determining the correctness of the part. Moreover, since the recognition module 130 selects an appropriate picture matching rule according to the part attribute when judging, the recognition speed can be speeded up, and the recognition rate can be improved.

In another embodiment, assuming that the standard part database records at least one standard part image of a plurality of standard motherboards and their position information and part attributes, the image capturing device 120 in the system 100 that automatically determines the correctness of the parts is in the shooting one. After the complete image of the tested motherboard of the tested motherboard, the identification module 130 will ask the user to input the motherboard identification information of the tested motherboard. After obtaining the motherboard identification information, the identification module 130 obtains all standard component images corresponding to the motherboard identification information from the standard component database, and then performs steps S230 and S240 according to the obtained standard component image. The action shown is to analyze whether the part configuration on the tested motherboard is correct. Since the manner of analysis is the same as or similar to the foregoing embodiment, it will not be described herein.

In summary, the present invention provides a method for automatically determining the correctness of a part, and extracts a corresponding image of the part to be tested from the complete image of the tested main board according to the part attribute and position information of the standard part image of the standard motherboard. And by identifying the module to analyze the image of each part to be tested by using the individual part attributes and position information of the standard part image, to generate a correct identification result of the part configuration in each part image to be tested.
