Abstract
A face recognition monitoring system based on spectrum and multi-band fusion, including a spectrum camera, a first module for acquiring a face spectral image, a second module for preprocessing data of the face spectral image, a face spectral image database and a third module for recognizing the face spectral image. The spectrum camera includes an optical lens and a silicon-based detector. The silicon-based detector includes a photoelectric conversion substrate and a filter film arranged thereon. The filter film includes N units each including a visible spectrum sensing area, a near-infrared spectral image sensing area and a RGGB image acquisition area. The N units cover all pixels on the photoelectric conversion substrate. A recognition method using the above system is also provided.
