The invention relates to a panoramic auxiliary parking device. A three-dimensional model adopted consists of four sectors corresponding to four photographic devices respectively, wherein each sector comprises an outer arc edge far away from a vehicle image, an inner arc edge close to the vehicle image and edge lines for connecting the two endpoints of the outer arc edge and the inner arc edge; the edge lines are straight lines; the curvature radiuses of the positions, close to the edge lines, of the inner arc edges corresponding to the left and right sides of a vehicle are 0.5-2 meters, the positions, close to the center, of the inner arc edges are approximate to straight lines, and have curvature radiuses of 23 to 29 meters, and the curvature radiuses of the positions, close to the center, of the inner arc edges corresponding to the front and rear sides of the vehicle are 3.5 to 5.5 meters; the curvature radiuses of all the outer arc edges are smoother in transition; transverse structure lines of every two adjacent sectors are in a G3 continuous state at the joint. According to the panoramic auxiliary parking device, real-time images of the photographic devices are spliced into a three-dimensional curved image on the basis of the three-dimensional model which is approximately tapered and has an approximately round rectangle-shaped cross section, section lines of the curved image are approximate to straight lines, and the distortion of the image is slight.
