[0008] The optical lens performance evaluation module receives the test data of various performances of the optical lens and makes a performance judgment. If the test data of various performances of the optical lens meet the requirements, the corresponding optical lens is marked as a normal lens. If there is a performance that does not meet the requirements in the optical lens, the corresponding optical lens is marked as a lens to be optimized, and the marking information of the optical lens and the judgment information of various performances are sent to the supervision terminal;

[0025] Furthermore, the supervision terminal is communicatively connected to the optical lens test monitoring module and the test precision classification module. The optical lens test monitoring module is used to monitor the test process of the optical lens and send the monitoring information to the test precision classification module; the test precision classification module analyzes the test performance of various performances during the monitoring period, and marks the corresponding performance as easy-to-control performance or difficult-to-control performance through analysis, and sends the marking information of each performance to the supervision terminal.
[0026] Furthermore, the specific analysis process of marking the corresponding performance as the performance that is easy to control or the performance that is difficult to control is as follows:

[0028] The number ratio of the abnormal measurement process corresponding to the target object i during the monitoring period is obtained and marked as the abnormal measurement matching value, and the abnormal measurement matching value is numerically compared with the preset abnormal measurement matching threshold. If the abnormal measurement matching value exceeds the preset abnormal measurement matching threshold, the target object i is marked as the test difficult to control performance.
[0029] Further, if the abnormal measurement match value does not exceed the preset abnormal measurement match threshold, the ratio of the test operation duration to the corresponding preset test operation duration threshold is marked as the test operation time detection value, and the ratio of the error operation frequency to the corresponding preset error operation frequency threshold is marked as the test false detection value;

[0037] Figure 2 This is a system block diagram of Embodiment 2 of the present invention. DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0039] Embodiment 1: Figure 1As shown, the performance evaluation system suitable for optical lens production proposed by the present invention includes an optical lens item-by-item testing module, an optical lens performance evaluation module, a production seamless connection module, an optical lens sales tracing module and a supervision terminal; the optical lens item-by-item testing module tests various performances of the optical lens, obtains the test analysis results of various performances, and sends the test data of various performances to the optical lens performance evaluation module, thereby realizing a comprehensive test of the optical lens, providing data support for the evaluation process of the optical lens performance evaluation module, and ensuring the accuracy of its analysis results;
[0040] It should be noted that the optical lens item-by-item test module tests the optical lens including resolution test, sharpness test, contrast test, distortion test, dispersion test, focal length test, aperture test, transmittance test, focus accuracy test and focus speed test.
[0041] Resolution refers to the ability of a lens to distinguish details of an object, usually expressed in lines per millimeter (lp / mm). In the resolution test, the optical lens is imaged and tested using a high-resolution test card or a specific resolution test pattern, and the minimum distinguishable line width or number of line pairs in the image is captured and analyzed.
[0042] Sharpness refers to the clarity of the lens image and the sharpness of the edges. In the sharpness test, the optical lens shoots a standard test image, such as the edge sharpness test chart, and evaluates it by analyzing the width of the transition area at the edge of the image or the sharpness index;
[0043] Contrast refers to the difference between light and dark in the lens image. In contrast testing, the optical lens is imaged and tested using test images with different contrast levels, and the brightness difference between the brightest and darkest parts of the image is measured and recorded.
[0044] Distortion refers to the geometric deformation produced by the lens when imaging, which is divided into barrel distortion and pincushion distortion. In the distortion test, the optical lens captures a test image with a standard geometric shape (such as a grid or dot array), and analyzes and records the degree of deformation of the geometric shape in the image.
[0045] Chromatic dispersion refers to the different degrees of refraction of light of different wavelengths by the lens, resulting in chromatic aberration in the image. In the dispersion test, a test image containing multiple colors is used to perform imaging inspection on the optical lens, and observe and record whether the edges of different color areas in the image are clear and aligned.
[0046] Focal length refers to the distance at which the lens images an object on the photosensitive element, reflecting the magnification of the lens. In the focal length test, the focal length of the optical lens is adjusted and a standard test image is taken to record the magnification of the image at different focal lengths.
[0047] Aperture refers to the size of the hole through which the lens light beam passes, and is expressed as the f-value. In the aperture test, the amount of light entering the optical lens at different aperture values, as well as the corresponding depth of field and image brightness are measured and recorded. In the transmittance test, a light source and a light intensity meter are used to measure and record the transmittance of the optical lens at different wavelengths.
[0048] Focus accuracy refers to the accuracy of lens focusing. In the focus accuracy test, the optical lens captures a standard focus test image, and measures and records the difference between the image clarity after the optical lens focuses and the expected clarity. Focus speed refers to the time required for the lens to focus. In the focus speed test, a timer is used to record the time required for the optical lens to complete focusing from the initial position.
[0049] The optical lens performance evaluation module receives the test data of various performances of the optical lens and makes a performance judgment. If the test data of various performances of the optical lens meet the requirements, the corresponding optical lens will be marked as a lens without abnormalities. If there is performance that does not meet the requirements in the optical lens, the corresponding optical lens will be marked as a lens to be optimized, and the marking information of the optical lens and the judgment information of various performances will be sent to the supervision terminal so that the supervisor can have a detailed understanding of the quality status of each optical lens produced and make reasonable disposal measures for each optical lens, thereby ensuring the quality of the optical lenses shipped out of the factory.
[0050] The production seamless docking module obtains the model of the corresponding optical lens, analyzes the production quality status of the corresponding model of optical lenses produced during the monitoring period, generates a production abnormality signal or a production qualified signal through analysis, and sends the production abnormality signal to the supervision terminal;
[0051] When the monitoring terminal receives a production abnormality signal, it issues a corresponding warning, which can reasonably analyze the production performance of the corresponding type of optical lens during the monitoring period and issue a timely warning, which is conducive to the supervisory personnel to strengthen the subsequent production supervision in time and ensure the quality of the optical lens produced; the specific analysis process of the production seamless docking module is as follows:
[0052] The number of optical lenses of corresponding models produced and subjected to performance test and evaluation during the monitoring period is obtained and marked as the optical lens production inspection value, and the number of lenses to be optimized is marked as the optical lens to-be-optimized value, the optical lens to-be-optimized value and the optical lens production inspection value are ratio-calculated to obtain the lens production characteristic value, and the lens production characteristic value is numerically compared with a preset lens production characteristic threshold value. If the lens production characteristic value exceeds the preset lens production characteristic threshold value, indicating that the production performance of the corresponding model of optical lenses produced during the monitoring period is poor, a production abnormality signal is generated;
[0053] If the lens production characteristic value does not exceed the preset lens production characteristic threshold, the performance information of the corresponding lens to be optimized that does not meet the requirements is obtained, and the performance that does not meet the requirements is marked as a negative feedback object;
[0054] The number of optical lenses whose corresponding performance is marked as negative feedback objects during the monitoring period is obtained and the ratio is calculated with the optical lens production inspection value to obtain the negative feedback ratio value, and each performance is set in advance to correspond to a set of preset quality impact weight values, all of which are positive numbers, and the greater the impact of the corresponding performance on the quality of the optical lens, the greater the value of the preset quality impact weight value that matches it;
[0055] The negative feedback ratio of the corresponding performance is multiplied by the corresponding preset quality impact weight value to obtain the negative impact coefficient; the negative impact coefficients of all performances are obtained and summed up to obtain the lens production performance value, and the lens production performance value is numerically compared with the preset lens production performance threshold. If the lens production performance value exceeds the preset lens production performance threshold, it indicates that the production performance of the corresponding model of optical lens produced during the monitoring period is poor, and a production abnormality signal is generated; if the lens production performance value does not exceed the preset lens production performance threshold, it indicates that the production performance of the corresponding model of optical lens produced during the monitoring period is good, and a production qualified signal is generated.
[0056] Furthermore, the production seamless docking module sends the production qualified signal to the optical lens sales tracing module. When the optical lens sales tracing module receives the production qualified signal, it will conduct a comprehensive analysis of the sales status of the corresponding model of optical lens during the monitoring period, generate a sales abnormality signal or a sales qualified signal through analysis, and send the sales abnormality signal to the supervision terminal. When the supervision terminal receives the sales abnormality signal, it will issue a corresponding warning to remind the supervisory personnel to strengthen the production control of the corresponding model of optical lens in time, further ensure the quality of the optical lens shipped from the factory, and thus improve the reputation and sales performance of the corresponding model of optical lens; the specific analysis process of the optical lens sales tracing module is as follows:
[0057] The sales volume of the corresponding model of optical lenses sold during the monitoring period is obtained and the ratio of it to the set standard sales volume is marked as the optical lens sales value, and the number of returns and exchanges of the corresponding model of optical lenses due to quality problems during the monitoring period is collected and marked as the optical lens return value; and all sales evaluation information for the corresponding optical lenses during the monitoring period is obtained, and the number of negative reviews about performance in the sales evaluation information is marked as the performance reputation anomaly;
[0058] The optical lens traceability value W is obtained by numerically calculating the optical lens sales value X, the optical lens return value F and the performance reputation abnormal value Y through the formula W=(t×F+n×Y) / (q×X+1); wherein q, t, and n are preset proportional coefficients with values greater than zero, and the larger the value of the optical lens traceability value W is, the worse the sales performance of the corresponding model of optical lens is in general during the monitoring period;
[0059] The optical lens traceability value W is numerically compared with the preset optical lens traceability threshold. If the optical lens traceability value W exceeds the preset optical lens traceability threshold, it indicates that the sales performance of the corresponding model of optical lens during the monitoring period is generally poor, and a sales abnormality signal of the corresponding model of optical lens is generated; if the optical lens traceability value W does not exceed the preset optical lens traceability threshold, it indicates that the sales performance of the corresponding model of optical lens during the monitoring period is generally good, and a sales qualification signal of the corresponding model of optical lens is generated.
[0060] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the supervision terminal is connected to the optical lens test monitoring module and the test precision classification module in communication. The optical lens test monitoring module is used to monitor the test process of the optical lens and send the monitoring information to the test precision classification module and the supervision terminal, which can not only provide information support for the analysis process of the test precision classification module, but also help the supervisor to grasp the performance information of each test process in detail;
[0061] The test precision classification module analyzes the test performance of various performances during the monitoring period, and marks the corresponding performances as easy-to-control performances or difficult-to-control performances through analysis, and sends the marking information of each performance to the supervision terminal, which is conducive to targeted follow-up training and formulation of management plans, and in the future, strengthens the test training and test supervision of testers on difficult-to-control performances, and ensures the test efficiency and test accuracy of subsequent performance tests; the specific analysis process is as follows:
[0062] All performances tested for the corresponding model of optical lens are obtained, and the corresponding performance is marked as target object i, where i is a natural number greater than 1; at the end of the test of the target object i of the corresponding optical lens, the test operation duration (i.e., the interval between the start time and the end time of the test) and the error operation frequency (i.e., the error frequency of the operator during the corresponding test process) of the corresponding test process are collected;
[0063] The test operation duration and the error operation frequency are numerically compared with the corresponding preset test operation duration threshold and the preset error operation frequency threshold, respectively. If the test operation duration or the error operation frequency exceeds the corresponding preset threshold, it indicates that the test performance of the corresponding test process for the target object i is poor, and the corresponding test process for the target object i is marked as an abnormal test process;
[0064] The percentage of the number of abnormal measurement processes corresponding to the target object i during the monitoring period is obtained and marked as the abnormal measurement matching value, and the abnormal measurement matching value is numerically compared with the preset abnormal measurement matching threshold. If the abnormal measurement matching value exceeds the preset abnormal measurement matching threshold, it indicates that the test operation for the target object i during the monitoring period is difficult, then the target object i is marked as difficult to control the test performance.
[0065] Furthermore, if the abnormal measurement match value does not exceed the preset abnormal measurement match threshold, the ratio of the test operation duration to the corresponding preset test operation duration threshold is marked as the test operation time detection value, and the ratio of the error operation frequency to the corresponding preset error operation frequency threshold is marked as the test false detection value;
[0066] Obtain all test operation detection values of target object i during the monitoring period and calculate their average to obtain the test efficiency analysis value, and calculate the average of all test false detection values of target object i to obtain the test error analysis value; numerically calculate the abnormal measurement matching value Qi, the test efficiency analysis value Mi and the test error analysis value Si by the formula HLi=u×Qi+g×Mi+e×Si to obtain the control evaluation coefficient HLi; wherein u, g, e are preset weight coefficients with values greater than zero, and the larger the value of the control evaluation coefficient HLi, the greater the overall difficulty of the test operation for target object i during the monitoring period;
[0067] The control evaluation coefficient HLi is numerically compared with the preset control evaluation coefficient threshold. If the control evaluation coefficient HLi exceeds the preset control evaluation coefficient threshold, it indicates that the test operation difficulty for the target object i during the monitoring period is generally large, and the target object i is marked as difficult to control performance in the test; if the control evaluation coefficient HLi does not exceed the preset control evaluation coefficient threshold, it indicates that the test operation difficulty for the target object i during the monitoring period is generally small, and the target object i is marked as easy to control performance in the test.
[0068] The working principle of the present invention is as follows: when in use, various performances of the optical lens are tested through the optical lens item-by-item testing module, the optical lens performance evaluation module receives the test data of various performances of the optical lens and makes performance judgments to determine the normal lenses and the lenses to be optimized, so as to facilitate reasonable disposal measures for each optical lens and ensure the quality of the optical lenses shipped out of the factory, and the production quality status of the corresponding types of optical lenses produced during the monitoring period is analyzed through the production seamless docking module, and the sales status of the corresponding types of optical lenses during the monitoring period is comprehensively analyzed through the optical lens sales tracing module when generating a qualified production signal, and the production control of the corresponding types of optical lenses is strengthened when generating a production abnormality signal or a sales abnormality signal, so as to further ensure the quality of the optical lenses shipped out of the factory, significantly reduce the management difficulty of supervisors, and have a high degree of intelligence.
