The invention belongs to the technical field of temperature measurement, and particularly relates to a method for measuring the temperature of a thin-wall test piece in a quartz lamp heating system. The method comprises the following steps: in a test preparation stage, arranging a first thermocouple on the upper surface of a test piece; arranging a plurality of second thermocouples on the lower surface of the test piece; performing radiation heating on the test piece through a quartz lamp tube heater, and respectively collecting the upper surface temperature of the test piece measured by the first thermocouple and the lower surface temperature of the test piece measured by the second thermocouple; a temperature calculation model is built according to the upper surface temperature and the lower surface temperature of the test piece, the input of the temperature calculation model is the lower surface temperature of the test piece, and the output is the upper surface temperature of the test piece; in the test stage, the first thermocouple is removed; performing radiation heating on the test piece through a quartz lamp tube heater, and collecting the lower surface temperature of the test piece measured by a second thermocouple; inputting the lower surface temperature of the test piece into the temperature calculation model, and outputting the upper surface temperature of the test piece.
