technical field [0001] The invention relates to the technical field of combining optics, electrical communication and computer science, and specifically refers to a mobile phone-based three-dimensional imaging method and imaging system for free-moving light field modulation. Background technique [0002] Light field modulation 3D imaging technology is a technology that utilizes auxiliary carrier frequency light field structured light illumination to realize a 3D image of a digital object. The imaging device records the fringe images formed by the surface of the object from different angles, and then uses a specific phase demodulation algorithm to obtain the phase information of the object from the deformed fringe image, and finally obtains the three-dimensional reconstruction image and display of the object through phase reproduction. The light field modulation imaging method has the advantages of non-contact, large field of view, stable imaging results, and easy implementat...
