Temperature Sensitive Paint (TSP) is a kind of special temperature sensor. TSP test is an essential approach to measure the surface temperature distribution, especially for high temperature, large area aero-engine components. The manual method of TSP test has a weak repeatability because it's heavily rely on the operator's personal experience and proficiency. Based on image processing algorithms, this paper presented an automatic method for TSP test and this method try to extract more information from the TSP image. The algorithms are tested on both standard test piece and combustor images. The result indicated that method in this paper has high automation and efficiency [1-3].
