s420, extracting a first feature of the first image frame and a first feature of the second image frame;
and S430, comparing the first characteristics of the first image frame and the second image frame, and determining that the alternative jig is a target jig for replacing the jig to be replaced when the first characteristics of the first image frame and the second image frame are consistent.
Specifically, according to the jig determining method provided by the embodiment of the application, the terminal device may receive the first image frame of the jig to be replaced and the second image frame of the alternative jig, which are transmitted by the image acquisition device. The first image frame and the second image frame may be further processed to extract the first feature in the first image frame and the second image frame. For example, an identification code of the jig, such as a bar code or a two-dimensional code. And then comparing and analyzing whether the first characteristics of the two image frames are consistent, namely, comparing the identification codes to determine whether the models corresponding to the two identification codes are consistent. When the first characteristic is found to be consistent through analysis, if the digits of the front part corresponding to the bar code are consistent, the model of the alternative jig is indicated to be consistent with the model of the jig to be replaced, namely, the alternative jig can be used as a target jig for replacing the jig to be replaced.

In order to better understand the jig determining method provided in the embodiment of the present application, a determining process is described in detail below with reference to fig. 5, fig. 5 is a schematic flow chart of the jig determining method provided in another embodiment of the present application, and as shown in fig. 5, the method includes:
s501, a database is generated, and the database comprises the standard characteristics of each type of jig and the management information of each jig.
Specifically, in the embodiment of the present application, a database for managing jigs may be constructed in advance. For example, management information such as a number, a current use position, an installation time, and the like of each jig may be entered first. In the use process of the jig, tracking information generated when each jig is replaced, such as replacement time, replacement people, replacement reasons and the like, can be recorded in real time. The database also includes standard features of each fixture, such as standard profile features of each fixture, such as dimensions and shapes.
S502, a first image frame of the jig to be replaced is obtained, and first features in the first image frame are extracted.
Specifically, a first image frame of the jig to be replaced, which is acquired by the image acquisition device, may be received. For example, a damaged jig to be replaced is placed on the placement object as shown in fig. 2 by a worker, and then the camera on the mounting body performs image acquisition on the jig to be replaced to acquire a picture including an identification code on the jig to be replaced, that is, a first image frame, and transmits the picture to the terminal device. After receiving the first image frame, the terminal device extracts a first feature in the first image frame, that is, extracts an identification code, such as a bar code, of the jig to be replaced in the image frame.
S503, determining the model of the jig to be replaced based on the first characteristic;
and S504, generating third prompt information based on the model of the jig to be replaced.
Specifically, after the first feature of the first image frame is extracted, if the identification code of the jig to be replaced is obtained, the model of the jig to be replaced, that is, the model of the alternative jig, may be determined according to the identification code. And then, third prompt information can be generated, wherein the third prompt information is used for indicating the model of the alternative jig, namely the model of the alternative jig is the same as that of the jig to be replaced.
Optionally, the specific information of the alternative jig may be further determined by using a database. For example, the model of each jig and other management information corresponding to the model are stored in the database. After the model of the jig to be replaced is obtained, the management information of the alternative jig matched with the model can be read from the database according to the model of the jig to be replaced, for example, the management information of all selectable jigs, such as the identification code, the storage position and the like, can be read.
Further, third prompt information can be generated based on the read management information to prompt a worker to quickly search for alternative jigs. The third prompt message may include tracking information of the alternative fixture, the current storage location, and the like. After the worker can select the alternative jig according to the prompt of the third prompt message, the alternative jig can be placed on the object to be placed for further judgment of the terminal equipment.
And S505, acquiring a second image frame of the alternative jig, and extracting a first feature in the second image frame.
Specifically, after the worker places the alternative jig on the placement object, the detection switch may detect that the jig needs to be detected at present, so as to trigger the camera to work, or the camera may be manually turned on by the worker. The camera may capture an image frame of the alternative fixture, i.e., a second image frame, and transmit to the terminal device. After the terminal device acquires the second image frame, the first feature in the second image frame can be extracted. Such as the identification code of the alternative jig.
S506, whether the first characteristics of the first image frame and the second image frame are consistent or not is judged.
Specifically, after the first characteristic of the alternative jig is extracted, the first characteristics of the jig to be replaced and the alternative jig can be compared and analyzed, whether the jig to be replaced and the alternative jig are consistent or not is judged, and whether the jig to be replaced and the alternative jig belong to the same type of jig or not is judged.
It can be understood that when the first characteristic of the first image frame matches the first characteristic of the second image frame, if the identifier of the to-be-replaced jig matches the identifier of the alternative jig, it indicates that the to-be-replaced jig and the alternative jig belong to the same type of jig, then a further determination may be made, i.e., S507 is executed. Otherwise, it indicates that the alternative jig is taken incorrectly, and S5061 is executed:
s5061, a first prompt message is generated and displayed.
Specifically, when judging that the alternative jig and the jig to be replaced do not belong to the same type of jig, first prompt information can be generated and displayed on a calculation display screen to prompt a worker that the model of the alternative jig is wrong. The working personnel can search the alternative jig again according to the first prompt message, thereby avoiding the jig type replacement error caused by human error and improving the jig replacement accuracy.
And S507, extracting a second feature of the second image frame, and reading a standard feature corresponding to the alternative jig from a database.
And S507, judging whether the second characteristic is consistent with the standard characteristic.
And S508, when the second characteristic is consistent with the standard characteristic, determining the alternative jig as a target jig for replacing the jig to be replaced.
S5081, a second prompt message is generated and displayed.
Specifically, after the current model of the alternative jig is found to be correct through the first characteristic judgment, the quality of the alternative jig can be further judged. That is, second features of the second image frame, such as contour features and texture features, can be further extracted. In addition, based on the model of the candidate fixture, the standard features corresponding to the candidate fixture, such as the profile features of the standard fixture corresponding to the candidate fixture, may be read from the database. The second feature may then be compared to the standard feature. And when the second characteristic of the alternative jig is judged to be consistent with the standard characteristic, the alternative jig is proved to be intact and can be used for actual production, namely, the alternative jig is determined to be the target jig for replacing the jig to be replaced. Otherwise, the alternative jig has quality problems, such as defective appearance. At this moment, second prompt information can be generated to prompt the worker, and the alternative jig has quality problems and needs to be selected again.
It can be understood that, in the above steps, after the second image frame is acquired, the first feature and the second feature of the second image frame may be extracted at the same time, such as extracting the identification code and the contour feature of the alternative fixture at the same time, which is not limited in this application.
It can be understood that after the target jig is determined to be finished, the jig to be replaced and the tracking information of the target jig can be updated in the database in real time, that is, the tracking information of the current replacement time, the replacement reason, the replacement applicant, the replacement result and the like of the jig to be replaced can be stored in the database; and tracking information such as the replacement time, the replacement object, the replacement reason, the replacement applicant, the replacement target position and the like of the target jig is stored in the database.
According to the jig determining method provided by the embodiment of the application, whether the model of the alternative jig is correct or not is determined by comparing and analyzing the first characteristics of the jig to be replaced and the alternative jig, and whether the alternative jig has a quality problem or not is determined by analyzing the profile characteristics and the standard characteristics of the alternative jig, so that the alternative jig is accurately replaced, the model error or the quality error caused by manually selecting the alternative jig is avoided, and the accuracy of selecting the alternative jig is improved.
