The invention relates to a system and a method for measuring the temperature of a thrust chamber of an attitude control engine, in particular to a system and a method for measuring a two-dimensional plane temperature field of the attitude control engine, and solves the technical problem that the highest temperature value and the position of the thrust chamber of the attitude control engine cannot be accurately measured and positioned. According to the attitude control engine two-dimensional plane temperature field measurement system provided by the invention, an N visual angle measurement system is established through the annular positioning device and the N signal acquisition devices, and in-situ calibration is realized through the high-temperature radiation signal generator and the annular positioning device, so that influence factors generating system errors are reduced, and the measurement precision of the system is improved. According to the attitude control engine two-dimensional plane temperature field
