An imaging apparatus, method and device, comprising an imaging member having an imaging surface of a spherical structure. An included angle between each of all parts of the spherical imaging surface and light emitted by an image source at an intersection of the imaging surface is 90°, and several imaging units are distributed on the imaging surface. By using a spherical projection surface, the image of a scene is entirely, completely and accurately acquired, the acquired image is displayed by a display device having the same structure corresponding to an inverted spherical display surface, and a highly realistic stereoscopic picture that is completely consistent with the scene is displayed, thereby solving the defect that the imaging method based on a planar projection surface is difficult to acquire and display the high-fidelity stereoscopic scene picture.
