Abstract

The invention relates to a vehicle body all-round view image bottom display method. The method includes the following steps that: S1, the vehicle body all-round view image of a vehicle is acquired; S2, the motion trajectories of the vehicle are estimated; S3, the motion trajectories of the four vertices of a vehicle bottom missing image in the vehicle body all-around view image are estimated according to the motion trajectories of the vehicle; S4, the historical image of the vehicle bottom missing image is acquired according to the motion trajectories of the four vertices; and S5, the currentframe of the vehicle body all-round view image is filled with the historical image, so that the historical image and the current frame image can be spliced and merged. According to the vehicle body all-round view image bottom display method of the invention, the motion trajectories of the vehicle are obtained; the motion trajectories of the bottom shadow of the vehicle can be obtained; the historical image of the bottom of the vehicle is obtained; and the historical image fills the current frame image, so that the historical image and the current frame image can be spliced and merged; and thevehicle body all-round view image can be completed, and it can be ensured that the bottom of the vehicle can be displayed in real time.

Description

technical field [0001] The invention relates to the field of car body surround-view images, in particular to a method for displaying the bottom of the car body surround-view images. Background technique [0002] The traditional panoramic image display system of a vehicle can only display the visible range captured by the cameras around the vehicle body after splicing and fusion, and cannot display the bottom of the vehicle body, so that users cannot obtain the environmental information of the bottom of the vehicle body in real time. [0003] The current vehicle panoramic view system mainly uses 4 cameras distributed around the car body to collect body images. displayed together on the user's screen. However, when displaying, because the camera cannot capture the image of the bottom area of ​​the body model, a shadow area that cannot be displayed appears at the bottom of the body model. analysis. Contents of the invention [0004] The purpose of the present invention is ...
