The invention discloses a laminar flow wing transition position measurement test method. The method comprises the following steps: 1, processing a laminar flow wing model and a sample wafer based on a temperature-sensitive paint technology; 2, obtaining a calibration relational expression of the temperature and the light intensity of the sample in a calibration cabin; 3, establishing a test scene; 4, determining static debugging parameters in the temperature-sensitive coating measuring system; 5, performing joint debugging on the temperature-sensitive coating measurement system and the wind tunnel measurement and control system to obtain a reference image, a background image and a sequence test image; and 6, carrying out test image acquisition on different states of the laminar flow wing, and carrying out post-processing on the test acquired images to obtain a gas flow transition image on the surface of the laminar flow wing model. According to the laminar flow wing transition position measurement test method provided by the invention, a laminar flow wing test mode based on the temperature-sensitive paint is creatively established, and compared with the prior art, the test effect has the remarkable advantages of high resolution and accurate transition position judgment.
