A method of producing a temperature model of a surface (3) of an object (2) using ultrasonic transducers (4, 5) comprises the steps of iteratively adjusting a temperature model by using measured travel times of ultrasonic waves and their predictions model-based. The ultrasonic waves used for producing the temperature model are preferably substantially non-dispersive ultrasonic waves. The method may further involve a height model of the surface (3), which height model is produced using substantially dispersive ultrasonic waves and is corrected by using the temperature model.
