Calibration label generation method and device, electronic equipment and medium

The invention provides a calibration label generation method and device, electronic equipment and a computer readable medium. The method comprises the steps: S1, initializing a white background, and initializing the global feature number as a first number; s2, generating random noise, multiplying the random noise by a preset coefficient, and superposing the random noise on the white background togenerate a first image; s3, carrying out fuzzy processing on the first image to generate a second image, calculating the number of features contained in the second image, and recording the number of the features as a second number; s4, comparing whether the second number is greater than the first number or not; if yes, updating the global feature number to be a second number; and S5, repeatedly executing the steps S2 to S4, and storing the first image as a calibration label when the number of times that the global feature number is not updated reaches a preset number of times. According to thescheme, the number of loc
