In the data of respective pixel be compared, if identical, the value of respective pixel in two-dimensional matrix is added into 1, specifically, previous frame
The data D1 for the pixel that 98th row the 56th arranges in image（98,56）The data of the pixel arranged with the 98th row the 56th in current frame image
D2（98,56）It is identical, then by two-dimensional matrix（98,56）Value A（98,56）Add 1.
Further, the data of each pixel in each frame image data and pair in previous frame view data
Answer the data of pixel to include before being compared, a threshold value is pre-set, for compared with each value of two-dimensional matrix；Institute
State threshold value and be preferably 20.
Further, each value in timing detection two-dimensional matrix, value is entered more than pixel data corresponding to the value of threshold value
Line flag, wherein, the time-out time of the timer is preferably 5 seconds, and specifically, BBP will be every detection in 5 seconds once
The size of each value of two-dimensional matrix, and compared with threshold value 20, by institute if thering is value to be more than threshold value 20 in two-dimensional matrix
The rubidium marking stated in two-dimensional matrix gets off.Such as when detecting two-dimensional matrix（55,44）Value A（55,44）More than threshold value 20,
Then by the image pixel data of the column position of the 55th row the 44th corresponding to mark.
I.e. specifically, step S300 comprises the following steps：
S301, when the number of the data and the respective pixel in previous frame view data of each pixel in each frame image data
During according to being compared identical, the value of respective pixel in two-dimensional matrix is added 1；
S302, a timer is set, when the timer expires, obtains each value in two-dimensional matrix；
S303, by each value in the two-dimensional matrix got compared with the threshold value pre-set, it will be worth more than threshold value
Pixel data is marked corresponding to value.
Step S400, BBP is by the data for the location of pixels being labeled in each two field picture element with two adjacent pictures
Prime number evidence is replaced after being averaged.
In the embodiment of the present invention, BBP is detected and obtained to be marked in the view data that camera thecamera head comes
The location of pixels of note, the data of the labeled location of pixels are replaced after being averaged with two adjacent pixel datas, specifically,
Such as the data of the labeled row the 44th of location of pixels the 55th row as described above are D（55,44）, two-dimensional matrix corresponds to A
（55,44）, its two adjacent location of pixels is respectively that the 55th row the 43rd row and the 55th row the 46th arrange, then the labeled picture
The data D of plain position（55,44）Two neighboring pixel data D will be replaced with（55,43）And D（55,46）Average value.Now when
After the data correcting of labeled location of pixels, the value of two-dimensional matrix will be changed into 0 corresponding to the labeled pixel.
Further, BBP by the data for the location of pixels being labeled in each two field picture element with two adjacent pictures
After prime number after being averaged according to replacing it, a time point will be set, it is when reaching at the time point that the value in two-dimensional matrix is clear
Zero, wherein, the time point is preferably the integral point time of each hour, such as 8:00,13:00 etc., when every integral point
During the time, automatic clear, BBP will be re-started detection by all values in two-dimensional matrix to image.
I.e. specifically, step S400 comprises the following steps：
The location of pixels being labeled in the view data that S401, BBP detection and acquisition camera thecamera head come；
S402, replaced after the data for the location of pixels being labeled in each two field picture element are averaged with two adjacent pixel datas
