The invention discloses a linear array camera based automatic panoramic acquisition system for the outer surface of a cylindrical surface, which mainly comprises a cylinder centering and clamping device, a rotating device, a shooting device and a central controller. A programmed program is burnt into a central controller consisting of a singlechip and the like, and N cycles are performed, so that pictures on the periphery of the outer surface of the cylindrical surface can be acquired; and the acquired pictures are combined in an organic form, so that an accurate panoramic developed pattern of the outer surface of the cylindrical surface is obtained. According to the system, the problem of panoramic development of the outer surface of the cylindrical surface is solved; the system can be applied to scientific experimental study such as acquisition of the developed outer surface of a cylinder sleeve of an internal combustion engine, research on cavitation distribution of the surface and fingerprint investigatio
