A multispectral imaging method and system is provided. A multispectral imaging method of the present invention includes determining an on-off combination of a plurality of light sources illuminating a scene; illuminating the scene with the light sources according to the on-off combination selected on the basis of a first control signal generated by a microcontroller; capturing an image of the scene by operating a camera on the basis of a second control signal synchronized with the first control signal; determining a plurality of spectral basis functions and weights of the spectral basis functions; and acquiring a continuous spectral reflectance by summing values obtained by multiplying the spectral basis functions and respective weights. The multispectral imaging method of the present invention is practical and efficient in that a continuous spectral reflectance image can be acquired with a minimized number of measurements required for obtaining spectral reflectance. Accordingly, the multispectral imaging method of the present invention can be applied to various fields, such as image reproduction and medical imaging, while overcoming performance limits of the conventional RGB imaging techniques. |
