[0026] It should be noted that the present disclosure does not limit the specific method for obtaining the first set of shooting parameters actually measured by the shooting device, and it can be selected according to the actual situation.

[0027] Optionally, the first set of shooting parameters actually measured by the shooting device can be determined according to the type of the shooting device.

[0029] S102. Predict the power of the strong light source in the first image currently captured by the shooting device according to the first set of shooting parameters, and obtain the predicted light source power of the first image.

[0030] It should be noted that the present disclosure does not limit the specific method for predicting the power of the strong light source in the first image currently captured by the shooting device according to the first set of shooting parameters and obtaining the predicted light source power of the first image, and it can be selected according to the actual situation.

[0031] Optionally, according to the first set of shooting parameters {O x , E x , D x}, the power of the strong light source in the first image currently captured by the shooting device can be predicted by means of fitting and interpolation to obtain the predicted light source power of the first image.

[0032] For example, the first calibration value and the second calibration value of the shooting parameters in the first set of shooting parameters {O x , E x , D x} can be obtained, and multiple basic combinations of the shooting parameters can be obtained according to the first calibration value and the second calibration value of the shooting parameters, where each basic combination includes the calibration value of the shooting parameters and the calibration value of the predicted light source power. Determine the number of shooting parameters in the first set of shooting parameters, and use the number of shooting parameters as the iteration times of the linear fitting of the predicted light source power. Starting from the basic combination, the predicted light source power is linearly fitted according to the iteration times to obtain the predicted light source power that matches the measured value of the shooting parameters.

[0033] S103. Obtain the predicted critical shooting duration of the shooting device under the first shooting parameter combination.

[0034] It should be noted that the present disclosure does not limit the specific method for obtaining the predicted critical shooting duration of the shooting device under the first shooting parameter combination, and it can be selected according to the actual situation.

[0035] Optionally, according to the first shooting parameter combination {O x , E x , D x}, the predicted critical shooting duration of the shooting device under the first shooting parameter combination can be obtained by means of fitting and interpolation.

[0036] For example, the first calibration value and the second calibration value of the shooting parameters in the first shooting parameter combination {O x , E x , D x} can be obtained, and according to the first calibration value and the second calibration value of the shooting parameters, multiple basic combinations of the shooting parameters are obtained, where each basic combination includes the calibration value of the shooting parameters and the calibration value of the predicted critical shooting duration. Determine the number of shooting parameters in the first shooting parameter combination, and use the number of shooting parameters as the iteration times of the linear fitting of the predicted critical shooting duration. Starting from the basic combination, the predicted critical shooting duration is linearly fitted according to the iteration times to obtain the predicted critical shooting duration.

[0037] S104. Perform shooting protection on the shooting device according to the predicted light source power and the predicted critical shooting duration.

[0038] In the embodiment of the present disclosure, after obtaining the predicted light source power P x and the predicted critical shooting duration T x , shooting protection can be performed on the shooting device.

[0039] Optionally, the first calibrated light source power and the second calibrated light source power corresponding to the predicted light source power can be obtained. According to the aperture size and exposure time in the first shooting parameter combination, as well as the first calibrated light source power and the second calibrated light source power, the first candidate shooting duration of the shooting device is determined, and the cumulative shooting duration of the shooting device is obtained. And according to the cumulative shooting duration, the first candidate shooting duration and the predicted critical shooting duration, it is judged whether the first shooting parameter combination is a safe shooting configuration. If the first shooting parameter combination is not a safe shooting configuration, shooting protection is performed on the shooting device.

[0040] Optionally, if it is determined that the first shooting parameter combination is not a safe shooting configuration, various forms of safety notifications can be generated, such as short message prompts (Toast) and pop-up windows (Alert), etc., to remind the user. Among them, the safety notification is used to remind the user that the shooting device has detected a strong light source in the current environment. Accordingly, the user can choose whether to continue the shooting based on the safety notification.

[0041] According to a shooting method of an embodiment of the present disclosure, by obtaining the first shooting parameter combination actually measured by the shooting device; according to the first shooting parameter combination, predicting the power of the strong light source in the first image currently captured by the shooting device to obtain the predicted light source power of the first image, obtaining the predicted critical shooting duration of the shooting device under the first shooting parameter combination, and performing shooting protection on the shooting device according to the predicted light source power and the predicted critical shooting duration. Thus, the present disclosure predicts the power of the strong light source in the first image currently captured by the shooting device through the first shooting parameter combination, can accurately detect the strong light under the shooting device, and according to the predicted light source power and the predicted critical shooting duration, can obtain a safe shooting parameter combination for the shooting device. Through the safe shooting parameter combination, shooting protection can be performed on the shooting device, ensuring the safety of the shooting device during the shooting process and being beneficial to improving the service life of the shooting device.

[0042] Figure 2 is a schematic flowchart of a shooting method according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 2 , the specific process of performing shooting protection on the shooting device according to the predicted light source power and the predicted critical shooting duration is explained, including the following steps:

[0043] S201, obtain the first calibrated light source power and the second calibrated light source power corresponding to the predicted light source power.

[0044] Optionally, after obtaining the predicted light source power P x , the first calibrated light source power P s1 and the second calibrated light source power P s2 corresponding to the predicted light source power can be determined according to the calibration gear.

[0045] For example, the first calibrated light source power and the second calibrated light source power can be selected from the calibration gears. Among them, the first calibrated light source power P s1 is the maximum gear less than or equal to the predicted light source power P x , and the second calibrated light source power P s2 is the minimum gear greater than or equal to the predicted light source power P x , that is, P s1 ≤P x ≤P s2 .

[0046] S202. Determine the first candidate shooting duration of the shooting device according to the aperture size and exposure time in the first shooting parameter combination, and the first calibrated light source power and the second calibrated light source power.

[0047] In the embodiments of the present disclosure, based on the predicted light source power, the first calibrated light source power, and the second calibrated light source power, the second candidate shooting duration and the third candidate shooting duration of the shooting device are determined according to the aperture size and exposure time in the first shooting parameter combination, and a linear fit is performed on the second candidate shooting duration and the third candidate shooting duration to obtain the first candidate shooting duration.

[0048] For example, through fitting and interpolation, according to the aperture size {O ro , exposure time E re and the first calibrated light source power P s1 , determine the second candidate shooting duration T oe1 of the shooting device, that is, determine the second candidate shooting duration T according to {O ro , E re , P s1}, oe1 According to the aperture size {O ro , exposure time E re and the second calibrated light source power P s2 , determine the second candidate shooting duration T oe2 of the shooting device, that is, determine the second candidate shooting duration T according to {O ro , E re , P s2}, oe2 .

[0049] In the embodiments of the present disclosure, after obtaining the second candidate shooting duration T oe1 and the third candidate shooting duration T oe2 , a linear fit can be performed on the second candidate shooting duration and the third candidate shooting duration to obtain the first candidate shooting duration T oex .

[0050] For example, the following formula can be used to perform a linear fit on the second candidate shooting duration and the third candidate shooting duration to obtain the first candidate shooting duration T oex :

[0051]

[0052] Where T oex is the first candidate shooting duration, P s1 is the first calibrated light source power, Px For predicting the light source power, P s2 For the second calibrated light source power, T oe1 For the second candidate shooting duration, T oe2 For the third candidate shooting duration.

[0053] S203. Obtain the cumulative shooting duration of the shooting device, and determine whether the first shooting parameter combination is a safe shooting configuration according to the cumulative shooting duration, the first candidate shooting duration, and the predicted critical shooting duration.

[0054] In the embodiment of the present disclosure, after obtaining the cumulative shooting duration T N , the first candidate shooting duration T oex , and the predicted critical shooting duration T s , it is possible to determine whether the first shooting parameter combination is a safe shooting configuration according to the cumulative shooting duration, the first candidate shooting duration, and the predicted critical shooting duration.

[0055] For example, after obtaining the cumulative shooting duration T N , the first candidate shooting duration T oex , and the predicted critical shooting duration T s , if (1 - T N ) * T oex > T s , it is determined that the first shooting parameter combination is a safe shooting configuration; if (1 - T N ) * T oex ≤ T s , it is determined that the first shooting parameter combination is not a safe shooting configuration.

[0056] S204. If the first shooting parameter combination is not a safe shooting configuration, perform shooting protection on the shooting device.

[0057] In the embodiment of the present disclosure, if the first shooting parameter combination is not a safe shooting configuration, that is, when (1 - T N ) * T oex ≤ T s , shooting protection is performed on the shooting device.

[0058] In the embodiment of the present disclosure, after performing shooting protection on the shooting device according to the predicted light source power and the predicted critical shooting duration, the predicted light source power of the third image can be predicted based on the predicted light source power of the first image and the predicted light source power of the second image, where the second image is the previous frame image adjacent to the first image, and the third image is the next frame image adjacent to the first image. Based on the predicted light source power of the third image, it is pre - judged whether the first shooting parameter combination is a safe shooting configuration for the third image.

[0059] For example, after obtaining the predicted light source power P of the first imagex and the predicted light source power of the second image After that, based on the predicted light source power P of the first image x and the predicted light source power of the second image predict the predicted light source power of the third image That is, the predicted light source power of the third image

[0060] In an embodiment of the present disclosure, after obtaining the predicted light source power of the third image it is possible to obtain the corresponding third calibrated light source power and fourth calibrated light source power of the predicted light source power of the third image. For the subsequent specific process of pre-judging whether the first shooting parameter combination is a safe shooting configuration for the third image, reference can be made to the above embodiments, and details will not be described here.

[0061] Optionally, if it is determined that the first shooting parameter combination is not a safe shooting configuration, various forms of safety notifications can be generated, such as: short message prompts Toast and pop-up windows Alert, etc., to remind the user. Among them, the safety notification is used to remind the user that the shooting device has detected a strong light source in the current environment. Accordingly, the user can choose whether to continue shooting based on the safety notification.

[0062] According to a shooting method of an embodiment of the present disclosure, by obtaining the first calibrated light source power and the second calibrated light source power corresponding to the predicted light source power, and according to the aperture size and exposure time in the first shooting parameter combination, as well as the first calibrated light source power and the second calibrated light source power, determine the first candidate shooting duration of the shooting device, obtain the cumulative shooting duration of the shooting device, and according to the cumulative shooting duration, the first candidate shooting duration and the predicted critical shooting duration, judge whether the first shooting parameter combination is a safe shooting configuration. If the first shooting parameter combination is not a safe shooting configuration, perform shooting protection on the shooting device. Thus, the present disclosure judges whether the first shooting parameter combination is a safe shooting configuration according to the cumulative shooting duration, the first candidate shooting duration and the predicted critical shooting duration. If it is determined that the first shooting parameter combination is not a safe shooting configuration, perform shooting protection on the shooting device, which ensures the safety of the shooting device during the shooting process, is beneficial to improving the service life of the shooting device, and can generate various forms of safety notifications when it is determined that the first shooting parameter combination is not a safe shooting configuration, improving the user experience.

[0063] ​In an embodiment of the present disclosure, before predicting the power of the strong light source in the first image currently captured by the imaging device according to the first shooting parameter combination, the detected light intensity value of the pixel points can be determined from the first shooting parameter combination, the first pixel points with the detected light intensity value greater than the light intensity threshold are determined, and the first pixel points are set with marks to determine at least one connected region of the first image. For each connected region, the number of pixel points in the connected region is obtained, and the light source corresponding to the first connected region with the number of pixel points greater than the preset number threshold is determined as a strong light source.

[0064] For example, if the detected light intensity value of the pixel point is D x , and the light intensity threshold is D T , if it is determined that the detected light intensity value is greater than the light intensity threshold, i.e., D x > D T for the first pixel points, and the first pixel points are set with marks, at least one connected region of the first image can be determined by means of the connected domain. For each connected region, the number of pixel points N x in the connected region is obtained, and the light source corresponding to the first connected region with the number of pixel points greater than the preset number threshold N T is determined as a strong light source, that is, when D x > D T and N x > N T , it is determined as a strong light source.

[0065] It should be noted that after determining the strong light source, the power of the strong light source in the first image currently captured by the imaging device can be predicted according to the first shooting parameter combination.

[0066] In an embodiment of the present disclosure, based on the strong light source corresponding to the first connected region, the first strong light set of the first image can be determined, the second strong light set of the second image can be obtained, and the light source tracking is performed on the first strong light set of the first image and the second strong light set of the second image to determine the matching relationship between the light sources in the first light source set and the second light source set.

[0067] Figure 3 is a schematic flowchart of a shooting method according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 3 , the specific process of performing light source tracking on the first strong light set of the first image and the second strong light set of the second image to determine the matching relationship between the light sources in the first light source set and the second light source set is explained, including the following steps:

[0068] S301, based on the strong light source corresponding to the first connected region, determine the first strong light set of the first image.

[0069] In the embodiment of the present disclosure, the number of pixel points in the connected region can be obtained, and the light source corresponding to the first connected region where the number of pixel points is greater than a preset number threshold is determined as a strong light source q1. Then, the first strong light set of the first image is {Q i} = {q1, …, q n}.

[0070] S302. Obtain the second strong light set of the second image.

[0071] In the embodiment of the present disclosure, at least one connected region of the second image can be determined. For each connected region, the number of pixel points in the connected region is obtained, and the light source corresponding to the second connected region where the number of pixel points is greater than a preset number threshold is determined as a strong light source q′1. Then, the second strong light set of the second image is {Q′ i} = {q′1, …, q′ n}.

[0072] S303. Perform light source tracking on the first strong light set of the first image and the second strong light set of the second image to determine the matching relationship between the light sources in the first light source set and the second light source set.

[0073] In the embodiment of the present disclosure, the matching weight between the strong light source i in the first strong light set and the strong light source j in the second strong light set can be obtained. Based on the first strong light set and the second strong light set, a bipartite graph is constructed. Based on the bipartite graph and the matching weight between the strong light source i and the strong light source j, Hungarian matching is performed to determine the matching relationship between the light sources in the first light source set and the second light source set.

[0074] Optionally, the number of overlapping points between the first connected regions corresponding to the strong light source i and the strong light source j can be obtained. The first pixel point in the first connected region corresponding to the strong light source i and the second pixel point in the first connected region corresponding to the strong light source j are obtained. According to the distance between the first pixel point and the second pixel point, the minimum distance is determined therefrom. According to the number of overlapping points, the minimum distance, and a preset weight bias, the matching weight between the strong light source i and the strong light source j is determined.

[0075] It should be noted that for the coordinate point (x i , y i ) of the first pixel point and the coordinate point (x′ i , y′ i ) of the second pixel point, where (x i , y i ) ∈ q i , (x′ j , y′ j ) ∈ q′ i , the distance between the first pixel point and the second pixel point is abs(x i - x′j ) + abs(y i -y' j ), then the minimum distance dist = min i,j (abs(x i -x' j ) + abs(y i -y' j ))

[0076] For example, after obtaining the minimum distance, according to the number of overlapping points, the minimum distance, and the preset weight bias, the matching weight between the strong light source i and the strong light source j can be determined according to the following formula:

[0077] w ij = area IOU -dist + dist0

[0078] where w ij is the matching weight between the strong light source i and the strong light source j, area IOU is the number of overlapping points, dist is the minimum distance, and dist0 is the preset weight bias.

[0079] Optionally, based on the first strong light set and the second strong light set, the positions of the strong light sources in the first strong light set and the second strong light set can be marked as 1, and the positions of the non-strong light sources in the first strong light set and the second strong light set can be marked as 0 to construct a bipartite graph (0-1 image).

[0080] In the embodiments of the present disclosure, after obtaining the bipartite graph and the matching weight between the strong light source i and the strong light source j, the Hungarian matching can be performed based on the bipartite graph and the matching weight between the strong light source i and the strong light source j to determine the matching relationship between the light sources in the first light source set and the second light source set. For example: q i and the optimal match q' i correspond to the same strong light source.

[0081] According to a shooting method of the embodiments of the present disclosure, the first strong light set of the first image is determined through the strong light source corresponding to the first connected region, the second strong light set of the second image is obtained, and the light source tracking is performed on the first strong light set of the first image and the second strong light set of the second image to determine the matching relationship between the light sources in the first light source set and the second light source set. Thus, the present disclosure determines the matching relationship between the light sources in the first light source set and the second light source set by performing light source tracking on the first strong light set of the first image and the second strong light set of the second image, and determines whether the strong light source is still within the shooting range of the shooting device, which is beneficial to improving the safety of the shooting device during the shooting process and extending the service life of the shooting device.

[0082] The specific process of obtaining any one of the predicted light source power and the predicted critical shooting duration will be explained below.

[0083] Obtain the predicted critical shooting duration of the shooting device under the first shooting parameter combination;

[0084] Figure 4 It is a flowchart of a shooting method according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 4 , the specific process of any one of the predicted light source power and the predicted critical shooting duration will be explained, including the following steps:

[0085] S401. Obtain the first calibration value and the second calibration value of the shooting parameters in the first shooting parameter combination, and obtain a plurality of basic combinations of the shooting parameters according to the first calibration value and the second calibration value of the shooting parameters, wherein each basic combination includes the calibration value of the shooting parameters and the calibration value of any one of the predicted parameters.

[0086] Optionally, a plurality of test shooting parameter combinations can be obtained. The test shooting parameter combinations at least include the calibrated light source power, the calibrated aperture size, and the calibrated exposure time. Configure the test shooting device based on the test shooting parameter combinations, and control the test shooting device to shoot. Record the critical shooting duration and the detected light intensity value when the test shooting device starts to be damaged. Generate the calibration result corresponding to the test shooting parameter combination according to the test shooting parameter combination, the critical shooting duration, and the detected light intensity value, and store it.

[0087] For example, for the calibrated light source power P i , the calibrated aperture size O i , and the calibrated exposure time E i , configure the test shooting device based on the test shooting parameter combination, record the critical shooting duration T i when the test shooting device starts to be damaged and the detected light intensity value D i , generate the calibration result {O i , E i , D i , P i , T i} corresponding to the test shooting parameter combination, and save the calibration result in the memory.

[0088] It should be noted that for the detection of shooting device damage, there is a point where the detected value D i is greater than the weak detected value D dark in a scene with extremely weak light, indicating that the camera module of the shooting device is damaged. A scene with extremely weak light can be constructed by blocking the lens. In a scene with sufficient light, when the shooting device shoots a high-reflection target, there is a detected value D i less than the strong detected value Dlight The points indicate that the camera module of the photographing device is damaged. Therefore, the scenarios for the damage test need to be consistent.

[0089] In the embodiments of the present disclosure, during the process of traversing and testing multiple combinations of test photographing parameters, based on the detected light intensity value and / or the strong light response duration of the currently traversed combination of test photographing parameters, a second combination of test photographing parameters that can be skipped for testing is determined from the remaining non-traversed first combinations of test photographing parameters among the multiple combinations of test photographing parameters, and the second combination of test photographing parameters is skipped during subsequent traversal.

[0090] Optionally, compare the detected light intensity value of the currently traversed combination of test photographing parameters l with the light intensity threshold. If the detected light intensity value of the combination of test photographing parameters l is less than or equal to the light intensity threshold, a combination in which the calibration value of each photographing parameter is less than the calibration value of each photographing parameter within the combination of test photographing parameters l is determined from the first combinations of test photographing parameters as the second combination of test photographing parameters.

[0091] Among them, the light intensity threshold D T , D T is the minimum value of D i in all results that satisfy T u ≥T i . T u is the shooting duration threshold. Optionally, the present disclosure does not limit the setting of the shooting duration threshold. For example, the shooting duration threshold can be 300 minutes.

[0092] For example, if the detected light intensity value D l of the combination of test photographing parameters l is less than or equal to the light intensity threshold D T , that is, D l ≤D T , if the combination of test photographing parameters is {O l , E l , P l}, O x ≤O l , E x ≤E l , P x ≤P l , then {O x , E x , P x} is used as the second combination of test photographing parameters, and it is not necessary to test {O x , E x , P x}.

[0093] In an embodiment of the present disclosure, according to the calibration values of each shooting parameter in the second test shooting parameter combination, as well as the critical shooting duration and detection light intensity value of the test shooting parameter combination l, a calibration result {O x ,E x ,D l ,P x ,T l} corresponding to the second test shooting parameter combination is stored.

[0094] In an embodiment of the present disclosure, the strong light response time of the currently traversed test shooting parameter combination g can be compared with the strong light response time threshold, where the test shooting parameter combination g is {O g ,E g ,P g}. If the strong light response time of the test shooting parameter combination g is less than or equal to the strong light response time threshold, a combination in which the calibration value of each shooting parameter is greater than the calibration value of each shooting parameter in the test shooting parameter combination g is determined from the first test shooting parameter combination as the second test shooting parameter combination.

[0095] For example, if the test shooting parameter combination g is {O g ,E g ,P g}, if the strong light response time T g of the test shooting parameter combination g is less than or equal to the strong light response time threshold T s , that is, T g <T s , the strong light response time threshold T s can be set to 5 seconds, and O x >O g ,E x >E g ,P x >P g , then {O x ,E x ,P x} is used as the second test shooting parameter combination, and {O x ,E x ,P x} does not need to be tested.

[0096] In an embodiment of the present disclosure, according to the calibration values of each shooting parameter in the second test shooting parameter combination, as well as the detection light intensity value and strong light response time of the test shooting parameter combination g, a calibration result {O x ,E x ,D g ,P x ,T g} corresponding to the second test shooting parameter combination is stored.

[0097] For example, for the aperture size O, the first calibration value and the second calibration value can be selected from the calibration levels, where the first calibration value O s1 is the largest level less than or equal to the measured value of the aperture size O x , and the second calibration value O s2 is the smallest level greater than or equal to the measured value of the predicted aperture size O x , that is, O s1 ≤O x ≤O s2 ; for the exposure time E, the first calibration value and the second calibration value can be selected from the calibration levels, where the first calibration value E s1 is the largest level less than or equal to the measured value of the exposure time E x , and the second calibration value E s2 is the smallest level greater than or equal to the measured value of the exposure time E x , that is, E s1 ≤E x ≤E s2 .

[0098] For example, for the light source power P, the first calibration value P s11 is the largest level where the detection value D s1 under {O s1 , E s111 is less than or equal to the detected light intensity value D x , and the second calibration value P s112 is the smallest level where the detection value D s1 under {O s1 , E s112 is greater than or equal to the detected light intensity value D x . The first calibration value P s1 and the second calibration value P s2 are determined in the same way under {O s121 , E s122 , and the first calibration value P s2 and the second calibration value P s1 are determined under {O s211 , E s212 , and the first calibration value P s2 and the second calibration value P s2 are determined under {O s221 , E s222 .

[0099] In the embodiments of the present disclosure, after obtaining the first calibration value and the second calibration value of the shooting parameters, multiple basic combinations of the shooting parameters can be obtained. For example: {O s1 , E s1 , P s111 , Ds111}, {O s1 , E s1 , P s112 , D s112}, etc.

[0100] S402. Determine the number of shooting parameters in the first shooting parameter combination, and use the number of shooting parameters as the number of iterations for the linear fitting of any prediction parameter.

[0101] S403. Starting from the basic combination, perform linear fitting on any prediction parameter according to the number of iterations to obtain the final predicted value of any prediction parameter that matches the measured value of the shooting parameter.

[0102] Optionally, starting from the basic combination, traverse the shooting parameters in the first shooting parameter combination in order. For the currently traversed shooting parameter k, pair up the candidate combinations of the shooting parameters iterated in the (k - 1)th iteration to obtain at least one candidate combination pair required for the kth linear fitting. Perform linear fitting on the candidate parameter combination pairs to obtain at least one candidate combination iterated in the kth iteration until the iteration ends. Among them, the two candidate combinations in the candidate combination pair include the same calibration values for shooting parameters 1 to shooting parameter (k - 1), different fitting values for any prediction parameter, and the measured values for shooting parameter k to the last shooting parameter.

[0103] For example, for the basic combinations {O s1 , E s1 , P s111 , D s111} and {O s1 , E s1 , P s112 , D s112}, it is possible to traverse the shooting parameters in the first shooting parameter combination in order to obtain at least one candidate combination pair {O s1 , E s1 , P x11 , D x} required for the kth linear fitting, and perform linear fitting on the candidate parameter combination pairs to obtain {O s1 , E s1 , P x11 , D x} in Obtain at least one candidate combination {O s1 , E x , P x1 , D x} iterated in the kth iteration. For the basic combinations {O s1 , E s2 , P s121 , D s121} and {O s1 , Es2 , P s122 , D s122}, the shooting parameters in the first shooting parameter combination can be traversed in sequence to obtain at least one candidate combination pair {O s1 , E s2 , P x12 , D x} required for the k-th linear fitting, and linear fitting is performed on the candidate parameter combination pairs to obtain {O s1 , E s2 , P x12 , D x} in Similarly, obtain P x21 , P x22 .

[0104] For example, for the basic combinations {O s1 , E s1 , P x11 , D x} and {O s1 , E s2 , P x12 , D x}, the shooting parameters in the first shooting parameter combination can be traversed in sequence to obtain at least one candidate combination pair {O s1 , E x , P x1 , D x} required for the k-th linear fitting, and linear fitting is performed on the candidate parameter combination pairs to obtain {O s1 , E x , P x1 , D x} in For the basic combinations {O s2 , E s1 , P x21 , D x} and {O s2 , E s2 , P x22 , D x}, the shooting parameters in the first shooting parameter combination can be traversed in sequence to obtain at least one candidate combination pair {O s1 , E x , P x2 , D x} in

[0105] Furthermore, for {O s1 , E x , P x1 , D x} and {O s2 , Ex , P x2 , D x} Perform linear fitting to obtain the final predicted value of any predicted parameter that matches the measured value of the shooting parameter {O x , E x , P x , D x} in Regarding the specific process of obtaining T x is the same as that of P x and will not be elaborated here.

[0106] According to a shooting method of an embodiment of the present disclosure, by obtaining the first calibration value and the second calibration value of the shooting parameters in the first shooting parameter combination, and based on the first calibration value and the second calibration value of the shooting parameters, obtaining a plurality of basic combinations of the shooting parameters, where each basic combination includes the calibration value of the shooting parameters and the calibration value of any predicted parameter, determining the number of the shooting parameters in the first shooting parameter combination, and using the number of the shooting parameters as the iteration times of the linear fitting of any predicted parameter, starting from the basic combination, performing linear fitting on any predicted parameter according to the iteration times to obtain the final predicted value of any predicted parameter that matches the measured value of the shooting parameters. Thus, the present disclosure ensures the accuracy and reliability of obtaining the final predicted value of any predicted parameter that matches the measured value of the shooting parameters by obtaining the final predicted value of any predicted parameter that matches the measured value of the shooting parameters, laying a foundation for subsequent shooting protection of the shooting device.

[0107] The following explains the specific application scenarios of the shooting method proposed in the embodiment of the present disclosure.

[0108] For example, as Figure 5 shown, if the shooting device is pre-configured with a shooting parameter set, the power of the strong light source in the image captured by the image sensor of the shooting device (camera terminal device) can be predicted to obtain the predicted light source power of the image frame, and the predicted critical shooting duration of the camera terminal device under the shooting parameter combination can be obtained. According to the predicted light source power and the predicted critical shooting duration, shooting protection can be performed on the shooting device, and it can be determined whether the shooting parameter combination is a safe shooting configuration. If the shooting parameter combination is not a safe shooting configuration, shooting protection is performed on the camera terminal device, the safe shooting configuration parameter range is determined in real time, and the user is reminded.

[0109] In summary, according to the shooting method of the present disclosure embodiment, through complete calibration data and high-dynamic detection values, the strong light sources of the image frames captured under any combination of shooting parameters can be predicted, and through the complete calibration data, the safe shooting parameter configuration range can be accurately divided, and the shooting device can be accurately protected during strong light scenes, reducing the user perception and improving the user experience.
