The present invention provides a temperature measurement device and a temperature measurement method. The temperature measurement device includes a first sensor, used for collecting a body surface temperature of an organism； a second sensor, used for collecting an ambient temperature； and a processing unit, which is electrically connected with the first sensor and the second sensor respectively, and is used for performing data processing on the body surface temperature according to the ambient temperature to obtain an actual body temperature of the organism. Due to the arrangement of the first sensor, the second sensor and the processing unit, the temperature measurement device can perform data processing on the collected body surface temperature according to the ambient temperature to make the obtained actual body temperature of the organism more accurate, and further to facilitate accurately judging the health status of the organism.
