Description

Technical Field

[0001] The present invention relates to the field of data verification technology, applicable to the field of financial leasing, and in particular to a method and device for verifying installation quality, a storage medium, and computer equipment. Background Art

[0002] With the advancement of communications technology, the financial leasing industry is installing GPS, oil-level monitoring, and tire-pressure monitoring devices on leased assets before leasing. These devices upload data for online data statistics, risk prevention, and information tracking. After installing these devices, the quality of the installation must be verified to ensure that the data reported by the devices matches the actual data generated by the leased assets.

[0003] In the existing technology, the construction photos uploaded by the equipment installation contractor after the construction is completed are obtained, and the frame number information in the construction photos is extracted and compared with the frame number information in the construction work order information issued by the financial leasing company. If the frame number comparison results are completely consistent, the verification is passed. If the frame numbers are inconsistent, manual verification is performed. However, due to the uncertainty of the quality of the construction photos (due to interference from uncertain factors such as shooting angle, image pixels, and shooting light), the pass rate of the existing automatic verification of installation quality data is low, and a large amount of manpower is wasted for manual verification, which not only reduces the efficiency of installation quality verification, but also increases the time and labor costs of installation quality verification.

[0067] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0068] The embodiment of the present invention provides a method for verifying installation quality, such as Figure 1 As shown, the method includes:

[0069] 101. Obtain construction photos of the equipment installation, and perform character recognition processing on the construction photos to obtain the first frame number information;

[0070] In an embodiment of the present invention, the current execution end obtains construction photos of the equipment installation, wherein the construction photos are photos taken at the construction site uploaded by the construction party after the construction is completed, and include the frame number information of the construction vehicle. The current execution end performs character recognition processing on the construction photos to obtain the first frame number information. The character recognition processing is used to characterize the analysis and recognition of text characters in the image. It can be completed using text recognition software OCR or a deep learning model. It generally includes steps such as feature extraction, binarization processing, and similarity calculation. The embodiment of the present invention does not make specific limitations. The first VIN information is used to represent information that distinguishes the identity of a vehicle. It is a set of codes assigned to a vehicle by the vehicle manufacturer in order to identify a particular vehicle, also known as the vehicle identification code (VIN). It consists of three parts: the World Manufacturer Identification Code (WMI), the Vehicle Feature Description (VDS), and the Vehicle Indication Code (VIS), a total of 17-bit codes, such as LC6TCGC6670008028, where the first 3 digits "LC6" are the World Manufacturer Identification Code (WMI), the middle 6 digits "TCGC66" are the Vehicle Feature Description (VDS), and the last 8 digits "70008028" are the Vehicle Indication Code (VIS), etc. This embodiment of the present invention does not make specific limitations.

[0071] It should be noted that the construction photos obtained during the verification correspond to the construction work orders, that is, during the verification, it is necessary to ensure that the construction photos and construction work orders corresponding to the same work order number are verified. The construction work order is the document assigned by the financial leasing company to the construction party.

[0072] 102. Extract the second vehicle frame number information from the construction work order, and compare the first vehicle frame number information with the second vehicle frame number information to determine the number of characters that differ in the comparison;

[0073] In an embodiment of the present invention, the current execution end extracts the second frame number information from the construction work order, wherein the second frame number information is the information entered by the financial leasing company before the construction work order is dispatched. The entry method can be manual entry, code scanning, etc., which is not specifically limited in the embodiment of the present invention. The second frame number information is used to represent the information that distinguishes the identity of the vehicle. It is a set of codes assigned to a vehicle by the vehicle manufacturer in order to identify a certain vehicle, also known as the vehicle identification code (VIN), which consists of three parts: the world manufacturer identification code (WMI), the vehicle feature description part (VDS), and the vehicle indication part (VIS), with a total of 17 digits. The current execution end compares the first frame number information with the second frame number information to determine the number of characters in the comparison difference. The specific comparison method can be to compare one by one in the order of the character positions. When the characters on the same character position are different, it is considered that there is a difference. For example, the character at the 7th character position in the first chassis number information is "8", and the character at the 7th character position in the second chassis number information is "6", then the number of comparison difference characters is increased by 1 until all 17 character positions are compared, and the final number of comparison difference characters is obtained. This embodiment of the present invention does not make specific limitations.

[0074] 103. Compare the number of characters resulting from the comparison with a threshold value for the number of characters with an error, and determine an installation quality verification result based on the comparison result.

[0075] In an embodiment of the present invention, the current execution end compares the number of characters of the comparison difference with the threshold value of the number of characters of the error, obtains a comparison result, and determines the verification result of the installation quality based on the comparison result. Among them, the threshold value of the number of characters of the error is a pre-set value, which can be 1, 2, 3, etc., and the embodiment of the present invention does not make a specific limitation. The comparison result can be divided into three cases: the number of characters of the comparison difference is less than the threshold value of the number of characters of the error, the number of characters of the comparison difference is equal to the threshold value of the number of characters of the error, and the number of characters of the comparison difference is greater than the threshold value of the number of characters of the error. When specifically determining the verification result of the installation quality, it is determined based on the above three cases, and the embodiment of the present invention does not make a specific limitation.

[0076] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to accurately set the error character number threshold, while improving the efficiency of installation quality verification and ensuring the accuracy of installation quality verification, another installation quality verification method is provided, such as Figure 2 As shown, before the step of comparing the number of characters of the comparison difference with the error character number threshold, the method further includes:

[0077] 201. Obtain historical verification records;

[0078] In an embodiment of the present invention, the current execution terminal obtains historical verification records, which are verification records of vehicles that failed automatic verification and then passed manual review. In the prior art, when comparing vehicle frame number information, automatic verification is passed only if the frame number comparison results are completely consistent. Otherwise, manual review is required. During manual review, manual comparison is performed, and verification is passed only if the manual comparison results are completely consistent. In an embodiment of the present invention, it is necessary to first save such verification data that has passed manual review to obtain historical verification records.

[0079] 202. Obtain the historical first frame number information and the historical second frame number information in the historical verification record, and compare the historical first frame number information with the historical second frame number information to determine the number of characters of historical comparison difference;

[0080] In this embodiment of the present invention, the current execution end obtains the historical first frame number information and the historical second frame number information from the historical verification record, compares the historical first frame number information with the historical second frame number information, and determines the number of characters that differ in the historical comparison. In this embodiment of the present invention, the process of obtaining the historical first frame number information is the same as step 101, the process of obtaining the historical second frame number information is the same as step 102, and the process of comparing the historical first frame number information with the historical second frame number information and determining the number of characters that differ in the historical comparison is the same as step 102, which will not be further described in this embodiment of the present invention.

[0081] It should be noted that, in the embodiment of the present invention, the historical verification record contains multiple record data, denoted as n, and the chassis number information is extracted and compared and analyzed for each record data to obtain a historical comparison difference character number corresponding to each record data, thereby obtaining n historical comparison difference character numbers, which is not specifically limited in the embodiment of the present invention.

[0082] 203. Determine the error character number threshold based on the historical comparison difference character number.

[0083] In an embodiment of the present invention, the current execution end determines the error character count threshold based on the number of historical comparison difference characters. The process may include: first, performing statistical processing on the historical comparison difference character counts, such as calculating the average of all historical comparison difference character counts to obtain the difference character average; or calculating the median of all historical comparison difference character counts to obtain the difference character median; or calculating the mode of all historical comparison difference character counts to obtain the difference character mode. Then, as needed, select one of the difference character average, difference character median, and difference character mode, and determine the selected value as the error character count threshold. For example, the number of different characters in all historical comparisons is {1, 2, 1, 1, 3, 4, 2, 2, 3, 2, 2, 2, ..., 2, 1, 2, 2, 4}. Through statistical calculation, the average value of the difference characters is 2.35, the median of the difference characters is 2, and the mode of the difference characters is 2. Then, the error character number threshold can be determined as 2.35 or 2 from the average value of the difference characters 2.35, the median of the difference characters 2, and the mode of the difference characters 2 as needed. This is not specifically limited in the embodiment of the present invention.

[0084] Furthermore, as a refinement and expansion of the above-mentioned embodiment, in order to quickly and accurately extract information from an electronic construction work order, another method for verifying installation quality is provided. The steps of extracting the second vehicle frame number information from the construction work order include:

[0085] Perform keyword matching on the construction work order to determine target keywords;

[0086] Information is extracted based on the target keyword to obtain the second vehicle frame number information.

[0087] In an embodiment of the present invention, the current execution end performs keyword matching processing on the construction work order. If the target information to be extracted is the second frame number information, the keyword can be set to "frame number". The current execution end compares the information in the electronic construction work order with the keyword "frame number". When the comparison results are consistent, it matches the "frame number" field in the electronic construction work order and determines the "frame number" field in the electronic construction work order as the target keyword. The current execution end extracts information based on the target keyword to obtain the second frame number information. For example, the characters in the text box corresponding to the target keyword in the electronic construction work order are extracted to obtain the second frame number information. This embodiment of the present invention does not make specific limitations.

[0088] Furthermore, as a refinement and expansion of the specific implementation of the above embodiment, in order to automatically verify the installation quality based on the error character count threshold in the current execution end and improve the efficiency of the installation quality verification, another installation quality verification method is provided. The steps of comparing the number of compared difference characters with the error character count threshold and determining the installation quality verification result based on the comparison result include:

[0089] If the number of characters with the comparison difference is less than or equal to the error character number threshold, the device installation verification is passed; or,

[0090] If the number of characters in the comparison difference is greater than the error character number threshold, the construction photo and the construction work order are sent to the manual review end for review based on the manual review interface.

[0091] In an embodiment of the present invention, the current execution end compares the comparison difference character count with the error character count threshold, and obtains comparison results including three situations: the comparison difference character count is less than the error character count threshold, the comparison difference character count is equal to the error character count threshold, and the comparison difference character count is greater than the error character count threshold. When the comparison difference character count meets the two situations of being less than or equal to the error character count threshold, the equipment installation verification automatically passes and the verification ends; when the comparison difference character count meets the situation of being greater than the error character count threshold, a manual review interface is obtained, and the construction photos and construction work orders are sent to the manual review end for review based on the manual review interface. For example, if the error character count threshold is 2, when the comparison difference character count is 0, 1, or 2, the equipment installation verification automatically passes and the verification ends; when the comparison difference character count is 3, 4, 5... or a value greater than 2, a manual review process is performed.

[0092] It should be noted that the manual review end in the above embodiment may be the current execution end, or may be a client end providing manual services or a server end providing manual services, etc., which is not specifically limited in the embodiment of the present invention.

[0093] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to ensure that the second frame number information in the construction work order issued by the financial leasing company is accurate and complies with the provisions of the national frame number standard during the equipment installation quality verification process, another installation quality verification method is provided, such as Figure 3 As shown, after the step of extracting the second vehicle frame number information from the construction work order, the method further includes:

[0094] 301. Obtain a check digit character from the second vehicle frame number information;

[0095] In this embodiment of the present invention, the second vehicle frame number information is entered by the financial leasing company before the construction work order is issued. This information can be entered manually, by scanning a QR code, or by other means, and is not specifically limited in this embodiment of the present invention. Because errors may be introduced during the entry process, compliance verification of the second vehicle frame number information generated in the construction work order after entry is required.

[0096] In an embodiment of the present invention, the current execution end obtains the check bit character from the second chassis number information. For example, if the 9th bit character is pre-set as the check bit, the character at the 9th bit is directly obtained from the 17-bit characters of the second chassis number information. For example, the character at the 9th bit obtained from the second chassis number information "LC6TCGC6670008028" is "6", etc. This embodiment of the present invention does not make specific limitations.

[0097] 302. Perform a compliance check on the check digit character based on a check digit character check rule, so as to determine the number of compared difference characters based on the second vehicle frame number information that passes the compliance check.

[0098] In an embodiment of the present invention, the current execution end performs a compliance check on the check digit character based on the check digit character inspection rules. For example, according to national standards, the remaining 16 characters except the check digit character are weighted and summed, and then the obtained sum value is divided by 11 to obtain the remainder value after division. The remainder value is compared with the value on the check digit character. If the comparison result is consistent, the compliance check of the second frame number information is passed, and the current execution end determines the number of comparison difference characters based on the second frame number information that has passed the compliance check. If the comparison result is inconsistent, it is considered that the information entered by the financial leasing company before dispatching the construction work order is wrong, and the current execution end can issue a reminder rectification information to enable the financial leasing company to rectify the entered information. Through the technical means in the embodiment of the present invention, the accuracy of the frame number of the order to be dispatched can be improved when dispatching, avoiding the situation where the system verification fails due to the error of the frame number of the order to be dispatched, and further improving the pass rate of the system verification.

[0099] Furthermore, as a refinement and extension of the above embodiment, in order to update the error character number threshold so that the updated error character number threshold better meets the system requirements, another installation quality verification method is provided, such as Figure 4 As shown, after the step of determining the verification result of the installation quality based on the comparison result, the method further includes:

[0100] 401. If the verification result is a manual review result, the verification record corresponding to the review result is stored to obtain an updated historical verification record;

[0101] In an embodiment of the present invention, the current execution end judges the verification result. If the verification result is a review result passed through a manual review channel, the verification record corresponding to the review result is stored so that the historical verification record is updated to obtain an updated historical verification record.

[0102] 402. Obtain the update history verification record based on a time interval, and determine the number of characters of the update history comparison difference based on the update history verification record;

[0103] In an embodiment of the present invention, the current execution end obtains the update history verification record based on a time interval, and determines the number of characters in the update history comparison difference based on the update history verification record. The time interval is a time interval pre-set as needed, which can be one week, one month, 60 days, etc., and is not specifically limited in the embodiment of the present invention. The specific process of determining the number of characters in the update history comparison difference based on the update history verification record is the same as step 202, the only difference being that the number of records in the update history verification record is greater than the number of records in the original history verification record, and is not specifically limited in the embodiment of the present invention.

[0104] 403. Determine an update error character count threshold based on the update history comparison difference character count, so as to perform a device installation quality verification operation based on the update error character count threshold.

[0105] In an embodiment of the present invention, the current execution end determines an updated error character count threshold based on the number of characters that differed from the updated history comparison. The specific process is the same as step 203, except that the number of characters that differed from the updated history comparison is greater than the number of characters that differed from the original history comparison. This is not specifically limited in this embodiment of the present invention. The current execution end verifies the quality of the device installation based on the updated error character count threshold, thereby periodically updating the error character count threshold to ensure that the updated error character count threshold better meets system requirements.

[0106] The embodiment of the present invention provides a method for verifying installation quality. Compared with the existing automatic verification technology for installation quality in the field of financial leasing, the present invention obtains construction photos of the equipment installation construction site corresponding to the construction work order, performs character recognition processing on the construction photos, and obtains the first frame number information; then extracts the second frame number information in the construction work order, compares the first frame number information with the second frame number information, and determines the number of characters with difference in comparison; finally, compares the number of characters with the error character number threshold, and determines the verification result of the installation quality based on the comparison result, thereby improving the automatic verification pass rate of the equipment installation quality. In the process of automatic verification of equipment installation quality, the present invention pre-sets the error character number threshold according to historical verification records, so that verification data with the difference character number within the error character number threshold automatically passes the verification, reducing the amount of data for manual review, improving the efficiency of installation quality verification, and reducing the time cost and labor cost of installation quality verification.

[0107] As the above Figure 1 The embodiment of the present invention provides a device for verifying the quality of installation. Figure 5 As shown, the device includes:
