A real number sine/cosine wave basis function transform circuit includes a window segmentation element, a first transform element, a second transform element and a root-sum-square (RSS) element. The window segmentation element is provided to segment an in-phase output signal and a quadrature output signal to output an in-phase window signal and a quadrature window signal. The first and second transform elements are provided to transform the in-phase window signal and the quadrature window signal using a real number sine/cosine wave basis function to obtain a first transformed signal and a second transformed signal, respectively. The RSS element is provided to calculate an RSS value of the first and second transformed signals and output a real number sine/cosine wave basis function transformed signal.

A non-contact body temperature measurement device includes a thermal imager, an anemometer and a processing unit. The thermal imager is provided to capture thermal images. The anemometer is provided to measure wind speed and output a wind speed signal. The processing unit is provided to process the thermal images according to the wind speed signal and remove the thermal image showing great variation in temperature between two consecutive frames. Consequently, an accurate body temperature can be measured through the processed thermal images.
