Image processing method and device

The invention discloses an image processing method, and the method can obtain a to-be-processed image, determines the connectivity between each pixel point in the to-be-processed image and a neighborhood pixel point corresponding to each pixel point, i.e., determines whether each pixel point and the neighborhood pixel point corresponding to each pixel point belong to the same plane or not. And then, the pixel points in the image to be processed line are traversed by line and/or column by column, and the plane label of each pixel point in the image to be processed is determined according to thedetermined connectivity, the plane labels corresponding to the pixel points belonging to the same plane being the same, and the plane labels corresponding to the pixel points belonging to different planes being different. The mode of traversing the pixel points in the to-be-processed image line by line and/or column by column and determining the plane label of each pixel point is adopted, and thepossibility that the to-b
