    Abstract: A linewidth measurement method and apparatus, a computing and processing device, a computer program and a computer readable medium are provided for measuring a width of a line. The linewidth measurement method includes: obtaining a target image of the line, the line including a first line segment; performing region connecting on an edge image or binary image of the target image to obtain a region connected image, the region connected image including a target connected region corresponding to a pattern of the line, and a pixel value of each pixel in the target connected region being different from that of each pixel outside the target connected region; determining a first edge point and a second edge point of the first line segment based on the region connected image, the first edge point being located on a first edge line of the first line segment, the second edge point being located on a second edge line of the second line segment, and the first edge line and the second edge line being oppositely arranged in a first direction; and determining a width of the first line segment according to the first edge point and the second edge point, and determining the width of the line according to the width of the first line segment.
