in the formula (1), F (i, m + 1) represents the calculated check value of the ith row of the view data and is packed at the position of the (m + 1) th column of the ith row of the view data; f (n +1, j) represents the calculated check value of the jth column of the view data and is packaged at the position of the jth column of the (n + 1) th row of the view data; h (i, j) represents the ith row and jth column pixel point of the view dataA set pixel value; h (i, 1) represents a pixel value at the position of a pixel point at the ith row and the 1 st column of the view data; h (1, j) represents a pixel value at the pixel point position of the jth column of the line 1 of the view data; a and b both represent integer variables; m represents the number of pixel points of each line of the view data; n represents the number of pixel points of each column of static image data or dynamic image data; [] 2 Indicating that the data in the brackets is converted into binary data; len { } represents the total bit number of binary numbers in parentheses;<<represents a left-shifted symbol; f (n +1, m + 1) represents a packed padding value for the view data at row n +1, column m +1, thereby re-padding the view data into matrix data;
step S402, using the following formula (2) to verify the processing output result to obtain the image picture pixel definition value of the processing output result,
in the above formula (2), Q represents the image picture pixel definition value of the processing output result, and the value range of Q is [0,1 ]]The larger Q represents the higher the image definition; q 1 A pixel sharpness value representing a horizontal direction of an image frame of the processing output result; q 2 A pixel definition value representing a longitudinal direction of an image frame of the processing output result; m represents the number of pixel points of each line of the image picture of the processing output result; n represents the number of pixel points of each column of the image picture of the processing output result; h (x, y) represents the value of the position of the pixel point of the x row and the y column of the image picture of the processing output result; the absolute value is obtained;
step S403, using the following formula (3), adjusting a preset definition threshold according to the data amount of the processing output result, and controlling whether the view data processing platform needs to perform a restart operation according to the adjusted definition threshold,
in the above formula (3), E represents a restart control value of the view data processing platform; q 0 Represents a preset sharpness threshold; k represents the number of pixel points of each line of the inspection image corresponding to the preset definition threshold; l represents the number of pixel points of each row of the inspection image corresponding to the preset definition threshold;
if E =0, determining that the view data processing platform operates normally;
and if E =1, determining that the operation of the view data processing platform is abnormal, and indicating the view data processing platform to restart.
