The invention provides a method for analyzing white pixel distribution of an image sensor, and the method comprises the steps: carrying out the binarization processing of image data, and obtaining a binary image; extracting white pixel distribution characteristics from the binary image; clustering and grouping the features, and marking the features of a clustering set to obtain a tag data set; structuring the equipment data to obtain hardware data, and constructing a data set by combining the hardware data with the tag data set; performing time sequence statistics on the tag data set, extracting a time domain generated by specific tag data in the data set, and constructing a sub-data set; processing the hardware data in the sub-data set through an algorithm to obtain the feature importance of the hardware data; arranging the hardware data according to the feature importance, and counting specific tag data and the first N most important features; and carrying out visual analysis on the specific label data, and
