A connected domain optimization based non-invasive scattering imaging method beyond a memory effect range, comprising: collecting speckle information of a sample to be imaged; calculating an autocorrelation image of the speckle information and obtaining an autocorrelation graph according to the autocorrelation image; obtaining a reconstruction result according to the autocorrelation graph, and using a connected domain to optimize the reconstruction result; calculating the autocorrelation of the optimized reconstruction result and normalizing to obtain an initial autocorrelation of an object; obtaining a reconstruction result sequentially according to the autocorrelation of one object obtained in the previous step, calculating the autocorrelation of the optimized reconstruction result using connected domain optimization and normalizing, and calculating in combination with the autocorrelation graph to obtain the autocorrelation of the other object; repeating the described steps of calculating the autocorrelation of two objects until the predetermined number of cycles is reached; and using a phase recovery algorithm and the calculated autocorrelation of the two objects to perform spatial domain reconstruction to implement non-invasive imaging. The method can implement scattering imaging of multiple objects in a wide viewing angle range.
