The light source intensity acquisition module is used for acquiring illumination intensity when ISP parameter test is carried out on photographic equipment under different test points;
For how to acquire the illumination intensity, as shown in fig. 1, an illumination instrument may be installed on each test target support, and before each test point test equipment group starts to test, an illumination intensity acquisition instruction is sent under the background test system, and after the intensity is acquired, the illumination intensity acquisition instruction is returned to the background test system and recorded.

The test result of the test point 5 is continuous pictures generated by the photographing device of M groups of ISP parameters under the dark state environment and the fixed test distance, and is recorded as D 5_m, wherein M is the current ISP parameter, and the value range is [1, 2. The test result of the test point 6 is continuous pictures generated by the photographing device of M groups of ISP parameters under the condition of fixed illumination intensity and fixed test distance, and is denoted as D 6_m, wherein M is the current ISP parameter, and the value range is [1, 2.
Based on the continuous pictures D l_i_m_n generated by the test points 1,2 and 3, the continuous picture D 5_m generated by the test point 5 and the continuous picture D 6_m generated by the test point 6, the brightness adjustment rate Sv i_m_n, the brightness target score Sl i_m_n and the number of times Sr i_m_n that no human face is detected are calculated, wherein the calculation method of Sv i_m_n is to calculate the time when the continuous picture data set continuous Th1 image face target brightness summarized by D i_m_n meets the optimal human face brightness interval, the smaller Sv i_m_n indicates the faster adjustment speed, the optimal human face brightness interval is [ Th1, th2], the optimal brightness value is th= (th1+th2)/2, and the brightness interval is an empirical parameter (typically, th1=80, th2=160, th=120). The calculation method of Sl i_m_n is that the mean square error between the face target brightness and the optimal brightness value of all continuous picture data sets is that the smaller Sl i_m_n is, the closer the adjusted brightness effect is to the brightness target. A larger Sr i_m_n indicates an unstable effect of the ISP parameters.
Then through the formulaCalculating brightness evaluation scores S1 m of ISP parameters of each group of photographic equipment, wherein Sv m=0.75*Sv1235m+0.25*Sv6m,Sv1235m is the brightness adjustment rate of test points 1,2, 3 and 5, and Sv6 m is the brightness adjustment rate of test point 6; sl m=0.75*Sl1235m+0.25*Sl6m,Sl1235m is the luminance target score for test points 1,2, 3, and 5, and Sl6 m is the luminance target score for test point 6; sr m=0.75*Sr1235m+0.25*Sr6m,Sr1235m is the number of times that test points 1,2, 3 and 5 cannot detect a human face, sr6 m is the number of times that test point 6 cannot detect a human face,/>、And/>Is a preset influencing factor.

Based on the continuous pictures D 4_m_n1 and D 4_m_n2 generated by the test point 4, the face target area of each picture in the pictures D 4_m_n1 and D 4_m_n2 is detected by a face detection algorithm, and the area is enlarged by 20% after the target is detected. Calculating the blurring degree of the amplified region by using a blur operator, obtaining the average blurring degree Sb m_n1 of the continuous pictures D 4_m_n1, the average blurring degree Sb m_n2 of the continuous pictures D 4_m_n2,
And then calculating a motion evaluation score Sb m of each group of ISP parameters of the photographing apparatus by a formula Sb m=C（C1*Sbm_n1+C2*Sbm_n2), wherein C1 and C2 are preset coefficients, c1+c2=1, and generally, the influence of the blur degree caused by the horizontal motion is greater than the blur influence caused by the treatment motion, and C2> C1.
Specifically, the evaluation module is used for analyzing and obtaining the identification evaluation score of each group of ISP parameters of the photographic equipment according to the test result of the sixth test point.
It should be noted that, the test result of the test point 6 is that, under the condition of a fixed illumination intensity and a fixed test distance, the continuous pictures generated by the photographing device of M groups of ISP parameters are recorded as D 6_m, where M is the current ISP parameter, and the value range is [1, 2. The video displayed by the video playing module in the test of the test point 6 is the video to be identified of the face recorded in each environment, and each person in the video only appears once and is in the registered person list. Wherein the number of registered persons is K, and the identity set is { FK }; the number of people K1 appearing in the video, the identity set is { FK1}, K is much larger than K1.
Matching the target identity obtained in the continuous pictures D 6_m with a registrant library, wherein the number of the non-repeated identity marks matched to { FK1} is recorded as Kr m (the larger and better the number of the correct matching is represented), the number of the non-repeated identity marks matched to the { FK } { FK1} set is recorded as Kw m (the smaller and better the number of the misplaced matching is represented), and the number of missed matching is recorded as Kl m=K1-Krm-Kwm (the smaller and better the number of the missed matching is represented as the insufficient face or the insufficient recognition score possibly caused by poor imaging quality).
Then through the formulaThe identification evaluation scores Sreg m, β1, β2, and β3 of the ISP parameters of the respective sets of photographing apparatuses are calculated as the set influence factors.
And the evaluation module is used for obtaining ISP parameters of the adaptive photographic equipment according to the brightness evaluation score, the movement evaluation score and the identification evaluation score.
