Specific embodiment
Specifically illustrate embodiments of the present invention with reference to the accompanying drawing, attached drawing is only for reference and illustrates use, does not constitute pair
The limitation of the invention patent protection scope.
As shown in Figure 1, on the one hand the embodiment of the present invention provides a kind of camera flashing elimination side based on Photoelectric Detection
Method, comprising:
The step of step 1, ambient light signal sampling.
The ambient light signal sample the step of include:
Ambient light signal is converted to corresponding brightness electric signal by step 101.
In an enforceable example, ambient light signal (can also be wrapped comprising flash signal by photoelectric converter
Containing other visible light signals) it is converted into brightness electric signal.
Step 102 is amplified and is filtered to the brightness electric signal.
The brightness electric signal of photoelectric converter output, filters out flip-flop by capacitive coupling, is input to amplifier progress
Amplification, then low-pass filtered device (cutoff frequency is set as 250Hz), filtering out other high-frequency interferencing signals, (traffic lights, LED light are dodged
Bright frequency is between 10Hz~200Hz), the A/D for being input to MCU (Micro Controller Unit, i.e. micro-control unit) connects
Mouthful.
Step 103 samples the brightness electric signal, is stored.
Since the maximum frequency of light flash is 250Hz, according to Shannon's theorems, the minimum sampling frequency C of MCU A/D is
500Hz, to improve accuracy, in the present embodiment, the sample frequency C of MCU A/D is set as 2kHz, the brightness that sampling is obtained
Value is stored in brightness array.
The step that step 2, environment optical flare frequency determine.
The environment light of flicker free is stable within the time short enough, and there are the brightness values of the environment light of scintillation
It then will appear fluctuation.By compared with luminance mean value, determining that be higher than luminance mean value is the wave crest of flashing, lower than luminance mean value
It is the trough of flashing.
The step that the environment optical flare frequency determines specifically includes:
Step 201, by each brightness value in brightness array respectively compared with the luminance mean value, if the brightness value is big
In the luminance mean value, then corresponding value of statistical indicant is 1, and otherwise corresponding value of statistical indicant is 0, and the value of statistical indicant is successively stored and is arrived
Value of statistical indicant array.
Step 202, the quantity for recording consecutive identical value of statistical indicant are counted as peak valley, are successively stored and are counted in array.
For example, the 1st peak valley count table is shown with 3 continuous mark values 1, then the peak valley counts J (1)=3；2nd peak valley
Count table is shown with 28 continuous mark values 0, then the peak valley counts J (2)=28；3rd count table is shown with 16 continuous mark values
1, then the peak valley counts J (3)=16；And so on.
Step 203 counts calculating environment optical flare frequency according to the sample frequency, the peak valley.
It may not be the number obtained in a complete cycle since first peak valley is counted with the counting of the last one peak valley
Value, therefore to reduce error, peak valley when calculating the environment optical flare frequency count selection the from the counting array
Two peak valley countings start, until the counting of penultimate peak valley terminates.
Specifically calculating step includes:
Step 2031 determines the number k that peak valley counts.
Step 2032 calculates each initial scintillation frequency of environment light.
Specifically, each initial scintillation frequency Mi=C/ of the environment light (J (2i)+J (2i+1)), wherein C indicates sampling frequency
Rate, i=1,2 ... n (n=[(k-2)/2], [] indicate round numbers), (J (2i) indicates that the 2i peak valley counts, J (2i+1) table
Show that the 2i+1 peak valley counts.
Step 2033 asks arithmetic mean of instantaneous value to obtain the environment optical flare according to the environment light initial scintillation frequency
Frequency.
Specifically, environment optical flare frequency M=(M1+M2+ ...+the Mn)/n.
For example, as shown in Fig. 2, being the example that the present invention calculates the environment optical flare frequency.
In this example, the sample frequency C=2000Hz.
Array A indicates brightness array, and array B indicates value of statistical indicant array, and array C indicates to count array.
Peak valley count J (i) be followed successively by J (1)=3, J (2)=28, J (3)=16, J (4)=26, J (5)=19, J (6)=
1, the number k=6, n=[(k-2)/2]=2 that peak valley counts.
Therefore, each initial scintillation frequency M (i) of environment light are as follows:
M1=C/ (J (2)+J (3))=2000Hz/ (28+16)=45.45Hz；
M2=C/ (J (4)+J (5))=2000Hz/ (26+19)=44.44Hz.
So environment optical flare frequency M=(M1+M2)/2=(45.45+44.44)/2=44.92 (Hz).
Step 3 updates the step of camera frame per second.
The step of update camera frame per second, specifically includes:
Step 301 determines camera frame per second undetermined according to the environment optical flare frequency and the initial frame per second of the camera.
It specifically includes:
If the initial frame per second p0 of environment optical flare frequency M >=camera, camera frame per second p'=[M] undetermined/
Q, wherein [M] indicates to take the integer value of M, the integer that Q is 1~10, and p' is the integer value in 15~120fps；
If the initial frame per second p0 of environment optical flare frequency M≤camera, camera frame per second p'=[M] * undetermined
Q, wherein [M] indicates to take the integer value of M, the integer that Q is 1~10, and p' is the integer value in 15~120fps.
For example, being 44Hz, the initial frame per second p0 of camera after rounding if the environment optical flare frequency M=44.92Hz
=30fps:
Due to M > p0, so camera frame per second p'=[M] undetermined/Q={ 44,22 }.
Step 302 determines camera frame per second according to camera frame per second undetermined.
It specifically includes: by the absolute value reckling in camera frame per second undetermined with the initial frame per second difference of the camera
It is determined as camera frame per second.
For example, 22 is poor with the initial frame per second p0 (30fps) of the camera in camera frame per second p'={ 44,22 } undetermined
The absolute value of value is minimum, therefore, final to determine that camera frame per second p is 22fps.
In another embodiment of the present invention, be the accuracy for further increasing judgement, after step 1, step 2 it
Before further include:
The step of step 11, environment optical flare threshold determination.
The step of environment optical flare threshold determination includes: to judge whether luminance mean value is more than pre- in the brightness array
If luminance threshold is, the step of ambient light signal samples is returned, otherwise further judges brightness value in the brightness array
Whether the difference of maximum value, minimum value and luminance mean value is more than default fluctuation threshold, is, carries out environment optical flare frequency and determines
The step of, otherwise return to the step of ambient light signal samples.
The predetermined luminance threshold value, default fluctuation threshold can be calibrated according to actual effect, for example, it is described preset it is bright
Degree threshold value may be configured as 15000lux, and the default fluctuation threshold may be configured as 20%.
