The invention relates to a Fourier single-pixel imaging method based on spectrum saliency, which comprises the following steps of generating a series of Fourier base images by a computer, projecting the Fourier base images to a target, detecting the total light intensity reflected by the target through a barrel detector, transmitting the total light intensity to the computer, and reconstructing a target image by the computer. According to the Fourier single-pixel imaging method, sparse measurement and image reconstruction of Fourier coefficients are carried out based on spectrum saliency, sampling is only carried out in a region possibly containing target spectrum saliency information according to the structural similarity of the spectrum, and the imaging efficiency is effectively improved. 本发明是一种基于频谱显著性的傅里叶单像素成像方法，该方法通过计算机生成一系列傅里叶基底图像投射到目标上，桶探测器探测到目标反射的总光强，并将其传输到计算机中，由计算机重构目标图像。该方法利用基于频谱显著性进行傅里叶系数的稀疏测量和图像重构，依据频谱的结构相似，仅在可能含有目标频谱显著信息的区域进行采样，有效提高了成像效率。
