The invention discloses a method for calibrating and correcting temperature measurement of an infrared probe as well as a corresponding temperature measuring method. The temperature measurement calibration and non-uniform correction process is as follows: the non-uniform correction is carried out firstly; the temperature measurement calibration is carried out after a collection parameter sum is generated; however, the non-uniform correction is not stopped simultaneously; and in the non-uniform correction, a step of circularly judging whether an extrusion exists in a parameter or not is carried out; and if so, the parameter is corrected; otherwise, the judgment is continuously carried out. A temperature measurement calibrating process comprises the following steps of: carrying out the non-uniform correction once by using the calculated non-uniform parameter for each probe response of collecting a temperature; then recording the temperature and probe response data; repeating the processuntil collecting enough data; and fitting the data to obtain a probe temperature response function.
