A hyperspectral characteristic band selection method and an active hyperspectral imaging device using the same. The method using a virtual dimension algorithm to calculate a number of endmembers of a hyperspectral image of a predetermined disease, and using between 1 time and 2 times the number of endmembers as a number of predetermined selected bands, and then selecting characteristic bands with a number matching the number of selected bands from a plurality of spectral bands in the image. The device comprises a base, light sources and a sensing portion, the light sources are respectively disposed on the base, bands emitted by the light sources are configured according to the characteristic bands calculated by the method. The sensing portion is disposed on the base and spaced apart from the light sources for receiving reflected light from an external target object irradiated by the light sources to obtain a hyperspectral image.
