[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] Figure 1 The flowchart of a method for adjusting an optical lens provided in the first embodiment of the present invention is applicable to the case of adjusting an optical lens. The method for adjusting an optical lens can be performed by an adjustment system for an optical lens. The adjustment system for an optical lens can be implemented by software and / or hardware. The adjustment system for an optical lens can be configured in an optical lens adjustment device. Optionally, the optical lens adjustment device can be an electronic device, which can be a notebook, a desktop computer, a smart tablet, etc., and the embodiment of the present invention does not limit this.

[0029] like Figure 1 As shown, an optical lens calibration method provided by an embodiment of the present invention specifically includes the following steps:

[0030] Step 1: Use an image sensor to collect a lens imaging image, analyze the image deformation of the lens imaging image, and obtain an image deformation value;

[0031] In some embodiments, an image sensor is installed and connected to an optical lens system, and the sensor receives focused light from the optical lens, converts the light into an electrical signal, and further processes the electrical signal to obtain a lens imaging image;

[0032] Analyze the image deformation of the lens imaging image;

[0033] In some embodiments, analyzing the image deformation includes radial distortion analysis and tangential distortion analysis. In the process of radial distortion analysis and tangential distortion analysis, a polynomial function is used to describe the radial distortion, and a linear function is used to describe the tangential distortion.

[0034] It should be noted that radial distortion is mainly caused by the change in the radial curvature of the lens, which is manifested as a smaller offset of points near the center of the image, while a larger offset of points far from the center; tangential distortion is mainly caused by the deviation in the installation process of the lens and the camera, which causes the points in the image to shift along the tangent direction;

[0035] The radial deformation and tangential distortion of the lens imaging image are analyzed respectively; the vertex at the lower left corner of the lens imaging image is set as the origin, and an XY two-dimensional rectangular coordinate system is constructed. In the case of no distortion, the coordinates of each ideal pixel point are marked as (x, y);

[0036] The radial deformation is analyzed by the formula: x1=x(1+k1r 2 +k2r 4 +…), y1=y(1+k1r 2 +k2r 4+…), and obtain the coordinates (x1, y1) after radial distortion; where k1, k2,… are radial distortion coefficients; r represents the distance from the ideal pixel to the center of the image, which can be obtained by

[0037] The radially distorted coordinates (x1, y1) are processed using the formula The radial distortion value HG is obtained; wherein c1 and c2 are preset proportional coefficients;

[0038] The tangential distortion is analyzed by the formula x2=x+[2p1xy+p2(r 2 +2x 2 )],y2=y+[2p2xy+p1(r 2 +2y 2 )], and obtain the coordinates (x2, y2) after tangential distortion; where p1 and p2 are tangential distortion coefficients; r represents the distance from the ideal pixel to the center of the image, which can be obtained by

[0039] The obtained tangentially distorted coordinates (x2, y2) are processed using the formula Obtain the tangential distortion value XB, where m1 is the preset proportional coefficient;

[0040] It should be noted that the lens is subjected to a series of rigorous tests using high-precision measuring equipment and optical test platforms. During the test, calibration plates with known geometric shapes, such as a chessboard, a dot array, etc., are photographed, and the degree of distortion of these shapes in the image is analyzed. The distortion coefficient is calculated by comparing the difference between the actual image and the ideal image.

[0041] The radial distortion value HG and the tangential distortion value XB are processed and the formula is used Obtain the image deformation value HY, where s1 and s2 are preset proportional coefficients;

[0042] It should be noted that the image deformation value indicates the degree of deformation of the lens imaging image. The larger the image deformation value, the greater the degree of deformation of the lens imaging image.

[0043] Step 2: Compare the image deformation value with the image deformation threshold, and determine whether the lens imaging image is qualified according to the comparison result. If it is unqualified, generate an unqualified signal;

[0044] The image deformation value is compared with the image deformation threshold to determine whether the lens imaging image is qualified. The comparison results are as follows:

[0045] If the image deformation value is greater than or equal to the image deformation threshold, a failure signal is generated, indicating that the lens imaging image is unqualified;

[0046] If the image deformation value is less than the image deformation threshold, a qualified signal is generated, indicating that the lens imaging image is qualified;

[0047] The technical solution of an embodiment of the present invention is: using an image sensor to collect a lens imaging image, analyzing the image deformation of the lens imaging image, and obtaining an image deformation value; comparing the obtained image deformation value with an image deformation threshold to generate a qualified signal and an unqualified signal; if an unqualified signal is generated, the lens imaging image is unqualified; the present invention analyzes the deformation of the optical lens imaging image and the various factors that affect the imaging, such as the curvature of the lens, the refractive index of the material, and the incident angle of the light; analyzing the deformation of the imaging image helps to reveal how these factors work together to affect the imaging quality of the lens.

[0048] Embodiment 2

[0049] like Figure 2 As shown, an optical lens calibration method provided by an embodiment of the present invention specifically includes the following steps:

[0050] Step 3: Based on the unqualified signal, all potential factors causing the lens imaging pattern to change are analyzed; and the change correlation value between each potential influencing factor and the change of the image deformation value is obtained;

[0051] Based on the unqualified signal, in order to determine the cause of the change in the lens imaging pattern, the factors that may cause the change in the lens imaging pattern are analyzed;

[0052] Mark the factors that may cause the lens imaging pattern to change as potential influencing factors;

[0053] It should be noted that potential influencing factors include but are not limited to lens assembly errors, such as the coaxiality, tilt angle, and focal length mismatch between lenses; lens curvature radius, thickness distribution; lens refractive index, etc.;

[0054] Analyze the influence of potential influencing factors on the lens imaging pattern change;

[0055] Specifically, different potential influencing factors are analyzed by constructing different models;

[0056] In some embodiments, by constructing a lens physical property model, potential influencing factors such as refractive index change, curvature radius, thickness distribution, etc. are analyzed; by constructing an optical system design model, potential influencing factors such as focal length, field of view angle, aberration, etc. are analyzed; by constructing a lens usage model, potential influencing factors such as installation accuracy, coaxiality between lenses, tilt angle, etc. are analyzed;

[0057] By adjusting the potential influencing factors, the change of the image deformation value after the potential influencing factors are adjusted is obtained;

[0058] Specifically, all potential influencing factors are randomly sorted, and according to the sorting results, one potential influencing factor is selected in turn for analysis, and the selected potential influencing factor is marked as a hypothetical influencing factor, and the remaining potential influencing factors are controlled to remain unchanged;

[0059] The data of the assumed influencing factors are used as the horizontal coordinates, and the data of the image deformation values ​​are used as the vertical coordinates to draw a scatter plot; in the obtained scatter plot, the points corresponding to the image deformation values ​​HY are marked as reference points;

[0060] Draw a straight line through the reference point and parallel to the X-axis in the scatter plot, marked as the reference horizontal line;

[0061] Difference processing is performed on the ordinates of all points in the scatter plot and the ordinates of the reference horizontal line, and the differences that are less than zero are marked as adjustment points;

[0062] Get the deformation correction value of each adjustment point;

[0063] Subtract the absolute value of the ordinate of the adjustment point from the ordinate of the previous adjustment point to obtain the deformation correction value;

[0064] Exemplarily, the adjustment points are marked as {T1, T2, ..., T n}, assuming that the coordinates of the reference point are (1, 10), and the coordinates of the first adjustment point T1 are (2, 7); then the deformation correction value of the first adjustment point is 3; the coordinates of the second adjustment point T2 are (3, 5); then the deformation correction value of the second adjustment point is 2;

[0065] It should be noted that a positive deformation value indicates that the image deformation value decreases as the assumed influencing factors are adjusted;

[0066] Get the proportion of valid points in the adjustment points;

[0067] Specifically, based on any adjustment point in the scatter plot;

[0068] The obtained deformation correction value is compared with the deformation correction threshold. The comparison process is as follows:

[0069] If the deformation correction value is greater than or equal to the deformation correction threshold, the point is marked as a correction point;

[0070] If the deformation correction value is less than the deformation correction threshold, the point is marked as a non-corrected point;

[0071] Get the number of corrected points in the scatter plot, and perform ratio processing on the number of corrected points and the number of adjusted points to obtain the ratio of the number of valid points, which is marked as YX;

[0072] Analyze whether the change of the deformation correction value of the adjustment point is regular;

[0073] It should be noted that if the deformation correction value of the adjustment point changes regularly, it means that the deformation correction value of the adjustment point maintains a relatively stable change pattern over a period of time, and there is a high correlation between the adjustment point and the deformation correction value;

[0074] Specifically, the variance of the shape change positive value of the adjustment point is calculated to obtain the corrected variance value of the shape change positive value of the adjustment point, which is marked as FC;

[0075] The obtained effective point number ratio YX and the corrected variance value FC are processed and the formula is used. Obtain the change correlation value GL, where a1 and a2 are preset proportional coefficients;

[0076] It should be noted that the change correlation value indicates the correlation degree of the assumed influencing factor to the change of the image deformation value; the larger the change correlation value, the greater the correlation degree of the assumed influencing factor to the change of the image deformation value;

[0077] Step 4: Compare the change correlation value with the change correlation threshold, and determine whether the potential influencing factor is associated with the unqualified lens imaging image according to the comparison result; if so, generate a correlation signal and mark the potential influencing factor as a correlation influencing factor;

[0078] The change correlation value is compared with the change correlation threshold. The comparison process is as follows:

[0079] If the change correlation value is greater than or equal to the change correlation threshold, a correlation signal is generated;

[0080] If the change correlation value is less than the change correlation threshold, a non-correlation signal is generated;

[0081] Based on the correlation signal, the assumed influencing factor is a correlation influencing factor of the image deformation value;

[0082] Based on the non-correlated signal, the assumed influencing factor is a non-correlated influencing factor of the image deformation value;

[0083] The technical solution of the embodiment of the present invention is: based on the unqualified signal, all potential factors that may cause the lens imaging pattern to change are analyzed; the change correlation value of each potential influencing factor and the change of the image deformation value is obtained; the obtained change correlation value is compared with the change correlation threshold to generate a correlation signal and a non-correlated signal; based on the correlation signal, the correlation influencing factor is obtained; the present invention analyzes the correlation influencing factors that cause the deformation of the optical lens imaging pattern, and optimizes the design according to these factors, which can improve the lens imaging clarity; it helps to enhance the application effect and reliability.

[0084] Embodiment 3

[0085] like Figure 3 As shown, an optical lens calibration method provided by an embodiment of the present invention specifically includes the following steps:

[0086] Step 5: Analyze the correlation influencing factors to obtain the correlation degree value; arrange the correlation influencing factors based on the correlation degree value, and adjust the optical lens according to the arrangement order of the correlation influencing factors;

[0087] Obtain a scatter plot of the influence of associated influencing factors on the image deformation map; mark and connect all adjustment points in the scatter plot to obtain an associated factor curve;

[0088] Obtain the area of ​​the region enclosed by the correlation factor curve and the reference horizontal line, and the number of adjustment points in the region; perform a ratio processing on the area of ​​the region enclosed by the correlation factor curve and the reference horizontal line and the area of ​​the standard region to obtain an adjustment range value, marked as FW; perform a ratio processing on the number of adjustment points in the region and the number of standard adjustment points to obtain an adjustable number value, marked as SL;

[0089] The obtained adjustment range value FW and adjustable quantity value SL are processed and the formula is used Obtain the correlation degree value CD, where b1 and b2 are preset proportional coefficients;

[0090] It should be noted that the correlation degree value indicates the influence degree of the correlation influencing factor on the image deformation value. The larger the correlation degree value, the greater the influence degree of the correlation influencing factor on the image deformation value.

[0091] Obtain the correlation degree values ​​of all correlation influencing factors, and sort the correlation influencing factors from large to small according to the correlation degree values ​​of the correlation influencing factors to obtain a correlation degree sequence;

[0092] Based on the correlation degree sequence, when the optical lens imaging image undergoes image deformation, the correlation influencing factors are adjusted once based on the correlation degree sequence, and the optical lens is calibrated by adjusting the correlation influencing factors until the lens imaging image is qualified;

[0093] The technical solution of the embodiment of the present invention is: analyzing the associated influencing factors to obtain the correlation degree value; arranging the associated influencing factors based on the correlation degree value, and adjusting the associated influencing factors in sequence according to the arrangement order until the lens imaging diagram is qualified; the present invention helps to more accurately control these factors by analyzing the influence degree of the factors causing the lens imaging deformation, thereby optimizing the imaging performance of the lens; by adjusting the parameters of the lens, the distortion, chromatic aberration and other aberrations in the imaging process can be significantly reduced, and the clarity and resolution of the image can be improved.
