Referring to fig. 4, in an exemplary embodiment, a door lock installation assisting method is applied to the terminal 100 in the implementation environment shown in fig. 1, and the structure of the terminal 100 may be as shown in fig. 2.
The door lock installation assisting method may be executed by a client running on the terminal 100, and may include the following steps:
and 310, shooting the door lock guide sheet with the guide sheet calibration component to obtain guide sheet image data.
First, it is explained that the guide vane calibration component is a standard component for calibrating the door lock guide vane, so that the conversion of the guide vane related image can be performed based on the standard component.
In one embodiment, the guide vane calibration component is a calibration background plate provided with standard markers, as shown in fig. 5. The middle of the calibration background plate is left empty (as shown by a white area) for filling the door lock guide sheet. The standard marker for the calibration background plate, which is used to fill the remaining non-empty part of the calibration background plate (as shown by the gray area), may be a standard checkerboard, as shown in fig. 6, or an array of dots, as shown in fig. 7.
Further, for the standard marker, when filling is carried out in the calibration background plate, the deviation of the distance and the distribution precision between the standard marker and the calibration background plate is not more than 0.01mm, so that the effectiveness of carrying out guide vane related image conversion is fully ensured.
Of course, in other embodiments, the guide plate calibration component may also be a standard marker that can be placed on the periphery of the door lock guide plate, for example, the standard marker is an item that is convenient for obtaining standard size in daily life, including but not limited to: card-type identification (e.g., identification card, driver's license), bank card, transportation card, bank note, coin, smart phone, beverage bottle cap, packaging box, etc.
Next, the guide patch image data includes moving image data and still image data. The moving image data refers to a moving image such as a video including a plurality of frames of images, and the still image data may be a still image such as a picture including one frame of image, as opposed to the moving image data. Therefore, the shooting of the door lock guide sheet can be performed for obtaining the video of a plurality of frames of images, and can also be performed for obtaining the picture of a single frame of image.
In this embodiment, the shooting is performed for a single frame image.
It can also be understood that the guidance piece image data uploaded to the server by the client is a picture including a single frame image, and thus, for the server, when the door lock guidance piece parameter calculation is performed, the picture is based on the single frame image.
It should be noted that, for the door lock guide piece on which the guide piece calibration member is placed, the guide piece image data represents not only the guide piece plane image but also the guide piece calibration member plane image. Taking the guide vane calibration component as an example of a calibration background plate provided with a standard marker, as shown in fig. 5, a plane image of the guide vane is shown as a white area, and a plane image of the calibration background plate is shown as a gray area.
And 330, uploading the guide sheet image data to the server, so that the server performs projection conversion on the guide sheet plane image represented by the guide sheet image data into a reference plane image according to the affine transformation matrix.
For the server, after receiving the image data of the guide sheet, the server can provide calculation services for key parameters required when the door lock is installed.
In a specific implementation of an embodiment, as shown in fig. 8, the guide vane calibration component is a calibration background plate provided with a standard marker. Accordingly, the projection conversion process of the guide vane plane image can comprise the following steps:
As mentioned above, the standard markers will fill the non-empty parts of the calibration background plate in the form of a standard checkerboard or an array of dots.
Therefore, the standard marker detection refers to detecting the corner points of the checkerboard filled in the calibration background plate, or detecting the lumps of the dots filled in the calibration background plate, so that the position of the standard marker in the calibration background plate can be obtained.
It should be appreciated that the user's shooting angle is ever changing, thereby causing various errors in the imaging process in the client. For the server, it is necessary to eliminate various errors in the imaging process, correct the planar images of the guide strip obtained from the various shooting angles into standard mode images, and calculate the parameters of the door lock guide strip according with the standard dimensions based on the standard mode images.
For this purpose, the server stores reference image data in advance, and corrects the guide piece plane image using the reference plane image indicated by the reference image data as a standard pattern image. The reference image data is obtained by shooting a calibration background plate by the service end. Accordingly, the position of the standard marker based on the reference image data in the calibration background plate will be obtained through standard marker detection performed on the reference image data.
Based on the above, the affine transformation matrix is generated by calculating the positions of the standard markers respectively corresponding to the reference image data and the guide piece image data. It can also be understood that a mapping relationship is established between the guide piece plane image and the reference plane image by the reflection transformation matrix, and the guide piece plane image can be converted into the reference plane image based on the mapping relationship.
And 350, receiving the door lock guide sheet parameters calculated by the server from the reference plane image, and assisting to install the door lock through the door lock guide sheet parameters.
Key parameters required for door lock installation include, but are not limited to: the position of the top and bottom hook, the thickness of the door, the width of the guide piece, the height of the guide piece, the position of the bolt opening relative to the guide piece, the opening position of the guide piece fixing screw, the number of the guide piece fixing screws, the outer edge shape of the guide piece, the type of the guide piece and the like.
In this embodiment, the door lock guide vane parameter is used to characterize key parameters related to the guide vane, such as door thickness, guide vane width, guide vane height, position of the bolt opening relative to the guide vane, opening position of the guide vane fixing screw, number of guide vane fixing screws, outer edge shape of the guide vane, type of the guide vane, and the like. The type of the guide piece refers to the type of the guide piece to which the door lock guide piece parameter belongs, and for example, the type may be a door side guide piece or a door frame side guide piece.
As shown in fig. 9, in a specific implementation of an embodiment, the door lock guiding sheet parameter calculating process may include the following steps:
in step 351, component feature extraction is performed on the reference plane image, and the relative component position is calculated from the extracted component features.
The reference plane image is a guide piece plane image after correction, based on which the part features include part edge features and part position features. Wherein, part edge characteristic further includes door frame edge, door plant edge, guide plate edge etc. and part position characteristic further includes spring bolt hole position, screw hole position etc..
Accordingly, the operators used for component feature extraction are different for different component features. Aiming at the edge characteristics of the component, adopting a line characteristic extraction operator; and aiming at the position characteristics of the part, adopting a lump characteristic extraction operator.
After the component features are extracted, the relative position of the components can be calculated from the extracted component features. Such as the spacing between the edge of the door frame and the edge of the guide strip, the spacing between the locations of the latch holes, and the spacing between the locations of the screw holes.
Further, the relative position of the components is represented by coordinate values.
Furthermore, during the extraction of the feature of the component, morphological image processing can be performed on the reference plane image, such as thinning, pixelation, edge extraction and the like, so as to eliminate noise in the reference plane image, and further, the accuracy of parameter calculation of the door lock guide sheet is improved, the success rate of door lock installation is fully guaranteed, and the efficiency of door lock installation is improved.
And step 353, converting the relative positions of the components into door lock guide sheet parameters according to a proportion.
Wherein the ratio is related to the guide vane indexing component. The guide vane calibration component is taken as a calibration background plate provided with standard markers for explanation, and the proportion is calculated by the distance between the positions of the standard markers in the calibration background plate and the design size of the calibration background plate.
Thus, after the proportion is obtained, the door lock guide piece parameter meeting the standard size can be calculated according to the relative position of the components based on the proportion.
Through the process, the auxiliary door lock installation process from the terminal to the server is realized, namely, the portability and the universality of the terminal are utilized, the user is guided to shoot the door lock guide sheet with the guide sheet calibration component placed, so as to obtain the image related to the guide sheet, the powerful computing capability and the data storage capability of the server are utilized, the high-efficiency and accurate image analysis and data verification are provided for the image related to the guide sheet, the accuracy of the required key parameter during door lock installation is fully ensured, the success rate of door lock installation is favorably improved, the efficiency of door lock installation is favorably improved, the installation experience of the user is further improved, the production cost of the door lock is favorably reduced, and the labor cost is reduced.
Referring to fig. 10, in an exemplary embodiment, before step 330, the method as described above may further include the following steps:
and step 410, carrying out validity check on the image data of the guide piece.
And the validity check refers to detecting the brightness and contrast of the image and/or detecting the integrity of the image, so that the accuracy of the parameter calculation of the subsequent door lock guide sheet is fully ensured.
Further, the detection of the image brightness and contrast is to determine whether the gray distribution in the graph gray histogram is uniform, for example, the concentrated range of the gray distribution is not less than 30% of the whole distribution area, so as to ensure that the image related to the guide vane is clear enough.

Parameter checks include, but are not limited to: judging whether the parameters of the door lock guide sheet meet a set range or not; and/or judging whether the door lock guide sheet parameters are matched with the door lock guide sheet parameters stored in the database; and/or judging whether the door lock type to which the door lock guide sheet parameter belongs accords with regional distribution or not, and then eliminating abnormal data in the door lock guide sheet parameter, thereby being beneficial to ensuring the success rate of subsequent door lock installation.
For the server, if the parameter verification is successful, the door lock installation is assisted according to the door lock guide sheet parameters successfully verified by the parameter verification.
For example, according to the door lock type to which the door lock guide sheet parameter belongs, whether the stock of the door lock manufacturer is sufficient or not is checked, if the stock is insufficient, the door lock manufacturer is prompted to produce the door lock according to the door lock guide sheet parameter, and the door lock is provided for shipment, so that before the door lock is installed, various door lock accessories required during door lock installation can be prepared in advance for a user according to the door lock guide sheet parameter, and the door lock installer can be arranged to install the door lock on the door or the user can install the door lock by himself.
On the contrary, if the parameter verification fails, a parameter verification failure message is generated, so that the user can shoot the door lock guide sheet again according to the unqualified door lock guide sheet parameter indicated by the parameter verification failure message.
Further, for the door lock guide sheet parameter with failed parameter verification, the server further analyzes whether the door lock guide sheet parameter belongs to an unknown case, for example, the door lock guide sheet parameter conforms to a predetermined range but is not backed up in a database, and the like, and accordingly, the server notifies a background worker to perform manual processing, so that unnecessary shooting again by the user is avoided.
Under the cooperation of the embodiment, the accuracy of the parameters of the door lock guide sheet is fully ensured through validity check, so that the success rate of door lock installation is favorably improved, and the efficiency of door lock installation is improved.
