Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments.
[0030] A Fourier single-pixel imaging method based on spectral saliency, such as figure 1 As shown, the imaging system includes a projector 3 for projecting a substrate image to an imaging target 1, and a barrel detector 4 for collecting reflected images of the imaging target; a computer 2 generates multiple groups of substrate images and projects them on the target, and the barrel detector detects to the total light intensity reflected by the imaging target, and the data collected are transmitted to the computer by the acquisition card 5, and the target image is reconstructed by the computer, such as figure 2 As shown, the specific steps are as follows:
[0031] Step 1, the computer generates a sinusoidal fringe base image, and projects it onto the imaging target through a projector;
[0032] Step 2, the computer receives the refl...
