The invention relates to a straight line detection method for a projection interactive system. Compared with the prior art, the straight line detection method solves the shortcoming that the existing straight line detection method cannot meet the actual needs. The straight line detection method comprises the steps of: edge pixel point detection, wherein edge pixel points are detected from a target image by utilizing a canny edge detection algorithm; edge pixel point screening, wherein diversified edge lines are processed based on different processing methods so as to determine the reservation or filtering of the pixel points; straight line fitting operation, wherein all lines in the target image are traversed to find the most suitable splicing lines, and the straight lines are spliced and fitted to obtain a straight line detection result; straight line filtering repetition, wherein the highly parallel straight lines with close distances are arranged to filter out repeated straight lines. The straight line det
