Cosmic ray radiography is the inner investigation technology for large structures using by the muon. The "Scan Pyramids Mission" was launched in September of 2015 for observation of Egyptian Pyramid. We had installed nuclear emulsion detectors in the Bent Pyramid and the Khufu's Pyramid. Cosmic ray radiography simulator was developed using by GEANT4 to estimate expected image by the survey. By the comparison between experiment data at the Descending Corridor in the Khufu's Pyramid and simulation result, the unknown void had been discovered behind the entrance of the Khufu's Pyramid.
