The present invention discloses a method for measuring the parameter of the universal raster based on LCD free stereo display device of cylindrical raster. The method comprises the following steps: 1) estimating an actual slope angle alpha value of the cylindrical raster based on the total-black and total-white RGB image; 2) estimating the actual line number LPI value of the cylindrical raster based on the total-black and total-white RGB image; and 3) testing the image at multiple viewing points based on the actual scenery, and fine-adjusting the actual slope angle alpha value and actual line number LPI value of the cylindrical raster. Compared with the existing method for measuring the parameter of raster, the method of the invention has the following advantages: firstly high universality for the cylindrical raster with random line number LPI value and random slope angle alpha value; secondly simplicity and convenience, wherein the test picture is not required to be printed, and the parameter of raster can be accurately measured by observing through the LCD free stereo display device of cylindrical raster; and thirdly high precision, the measuring process is combined with actual scenery for testing image with multiple viewing points to lead to more accurate raster parameter which is obtained by measuring.
