The invention provides a three-dimensional 360-degree panorama image system and an implementation method thereof. The 3D effect within 360 degrees around a model car as a core can be achieved, so that a driver and passengers clearly and visually know the position relation between the car and a barrier, and the driving safety is improved. The implementation method comprises the steps that a correspondingly-proportional car three-dimensional image model is made according to actual outer contour dimension data of a car; peripheral images are collected through a photographic device, and the peripheral images are combined to the periphery of the car three-dimensional image model according to coordinates and proportions on the basis of the position and angle of the photographing device relative to the car to form a three-dimensional panoramic image capable of displaying the car and the peripheral conditions of the car; the three-dimensional panoramic image is displayed on a multimedia system and moved or rotated through keys.
