The invention discloses a 360-degree panoramic parking assistance system which comprises an MCU (microprocessor control unit) integrated circuit, a front camera, a rear camera, a left camera, a right camera, a 360-degree video module, a 360-degree panoramic video output circuit, a left turning detecting circuit, a right turning detecting circuit and a reversing detecting circuit. The front camera, the rear camera, the left camera and the right camera are distributed at four angles of an automobile so as to acquire front, rear, left and right image data by means of photographing; an input end of the 360-degree video module is connected with output ends of the front camera, the rear camera, the left camera and the right camera; the 360-degree panoramic video output circuit is connected with an output end of the 360-degree video module and is used for outputting 360-degree panoramic image data and front, rear, left and right one-way image data. The 360-degree panoramic parking assistance system has the advantages that rear/left/right and panoramic photographed images can be displayed via a vehicular display, so that one-way vision conditions of the automobile can be clearly seen, and the automobile can be turned safely and easily; the panoramic photographed images are small, the small images can be observed, accordingly, surrounding conditions of the automobile can be clearly seen when the automobile is turned, dead space positions can be prevented, and the automobile can be safely parked.
