| titleOfInvention | A method for extending the dynamic range of single-pixel imaging |
| abstract | The invention discloses a method for expanding the dynamic range of single-pixel imaging. First, low-resolution imaging is performed on a target scene, then bright and dark target areas are divided according to a threshold, and projection patterns of the corresponding areas are generated, and then PIN (low gain) ) and PMT (high gain) to collect the light intensity information of the bright and dark areas, use the TVAL3 compressed sensing algorithm to reconstruct the bright and dark target images, and finally fuse the bright and dark target images to obtain the target scene image. The invention completes single-pixel imaging of irregular areas; uses TVAL3 as the reconstruction algorithm, reduces the background noise of the restored image, and at the same time reduces the influence of the lack of orthogonality of the Hadamard matrix on the quality of the reconstructed image; suppresses the dark target from being damaged by The effect of erasing realizes the enhancement of dark targets, improves the dynamic range of imaging, and enables the practical application of single-pixel imaging technology. |
