The invention relates to the field of image data processing, in particular to a segmentation method for a lung ultrasound image. Obtaining a lung ultrasonic grayscale image; obtaining a gray value change curve of each row of pixel points; acquiring a proportion parameter of the gray value change curve; sequentially obtaining a maximum value point corresponding to the maximum value point of each row of gray value change curve in the next row of gray value change curve, and obtaining a maximum value point sequence corresponding to the maximum value point in the first row of gray value change curve; obtaining the B line probability of a maximum value point in each row of gray value change curve; obtaining the B line degree of each maximum value point sequence; and marking the maximum value points in the maximum value point sequence of which the B line degree is greater than the threshold value in the image. According to the method, the maximum value point in each row of gray value change curve in the image is sc
