Abstract

The invention discloses a hyperspectral batch-type nondestructive detection method and system for quality of agricultural and livestock products. The method comprises: presetting the number of single hyperspectral batch-type samples, determining the number of coupling fibers, and further determining the size and arrangement of the fibers; establishing a correspondence of each fiber with spatial-dimension and spectral-dimension photosensitive regions on an area array detector, and establishing a correspondence of a fiber corresponding detection sample with a near-infrared spectral signal responsively acquired by the assigned photosensitive region of the detector; establishing a quality detection model using quality indexes of the batch-type detection samples and near-infrared spectrum acquired by the detector; subjecting samples to be detected to batch feeding, acquiring near-infrared spectrums of the samples, substituting to the quality detection model, outputting the quality indexes of the samples to be detected respectively to finish hyperspectral batch-type rapid destructive detection for the quality of agricultural and livestock products. The detection speed limit problem and model transfer bottleneck problems can be broken through for the detection of the quality of agricultural and livestock products.
