The invention discloses an embedded high-space and high-
spectral resolution video acquisition
system. A video acquisition card of the
system conveys the acquired RGB and gray scale videos to a memory, and a processor
decodes the videos to separate
RGB image signals and gray scale image signals and synchronously aligns and corrects the
RGB image signals and the gray scale image signals; a
principal component analysis method is used for reducing the spectral information dimension of pixel points so as to simplify the calculated amount; then a spectral propagation
algorithm of bilateral filtering is executed on the processor in a multi-thread parallel mode so as to obtain spectral information of all pixel points of video frames; high-resolution spectral information is recovered by the
principal component analysis method; data is stored in the memory, and acquisition,
processing and analysis processes are displayed by display equipment; and finally,
spectral data in the memory is transmitted to a remote host through the network. The
system disclosed by the invention realizes integration of acquisition,
processing, analysis and display processes of the videos, has the characteristics of
miniaturization and integration, and is convenient to carry and use.
