AI Technical Summary
Snapshot-type spectral imaging systems suffer from slow spectral reconstruction speed, weak noise resistance, and low resolution, making it difficult to achieve real-time acquisition and accurate reconstruction.
Singular value decomposition is used to reduce the L2 regularization optimization algorithm. Combined with multiple filter pixel channels with different micro-nano structures, the spectral reconstruction process is optimized by singular value decomposition, and the reconstruction speed and resolution are improved by using the L2 regularization optimization algorithm.
It achieves near real-time spectral reconstruction of snapshot-type spectral imaging system, improves noise resistance and resolution, enhances the advantages of real-time image acquisition, and is suitable for fields such as real-time spectral recognition and obstacle avoidance.
