1. A method for constructing a 3D panoramic view model, comprising:
identifying a target object in an environment image obtained from a camera of a vehicle, and determining first coordinates of the target object in a first coordinate system corresponding to the environment image;
converting the environment image to an aerial view from a perspective transformation, and determining second coordinates of the target object in a second coordinate system corresponding to the aerial view according to the first coordinates;
determining a third coordinate of the target object in a third coordinate system corresponding to the camera according to the second coordinates;
determining a fourth coordinate of the target object in a fourth coordinate system corresponding to the vehicle according to the third coordinate, and determining an initial distance between the target object and the vehicle according to the fourth coordinate; and
determining a target distance according to a preset correction parameter and the initial distance, and constructing a target 3D panoramic view model of the vehicle according to the target distance and the environment image.
