Problems solved by technology

[0008] Usually, the 3D panoramic parking assistance system uses a super wide-angle lens and a fisheye lens, and its deformation and distortion are difficult to correct accurately, so that the formed 3D panorama is seriously deformed and the scene is unreal; in the selection of the three-dimensional projection surface, The existing 3D model is in the shape of a bowl, and part of the image on the wall and bottom of the bowl is distorted and deformed seriously; 3D panorama Figure four The directional image has uneven brightness, inconsistent brightness in overlapping areas, and there are problems such as splicing traces
[0009] These problems affect the user experience, and even increase the danger of parking because of the unclear recognition of the scene

Abstract

The invention discloses a 3D panorama parking assistance system and belongs to technologies applied to the field of automobile safety aided driving. The 3D panorama parking assistance system comprises a camera input module, an image correcting module, a three-dimensional projection module, an image splicing module and an image display module. The system shows the conditions around an automobile to a driver truly through a three-dimensional image, so that safety in the automobile parking process is improved. According to the system, a plurality of machine vision and digital image processing algorithms are integrated and combined with multiple advanced technologies of the machine vision field, so that the automobile parking process is higher in safety.

Description

[0001] Technical field: [0002] The invention relates to presenting the three-dimensional scene of the surrounding conditions of the automobile more truly to the driver so as to improve the safety of automobile parking, belongs to the fields of automobile electronics and machine vision, and in particular relates to the field of automobile safety assisted driving. [0003] Background technique: [0004] In recent years, with the rapid development of the automobile industry, the number of automobiles in our country has also increased sharply. At the same time, the proportion of non-professional drivers among automobile drivers has also increased significantly. When reversing in crowded and narrow places such as streets, garages and parking lots, scratches are prone to occur due to the blind spots of conventional optical rearview mirrors. [0005] In order to solve the problem of blind spots, a traditional 2D panoramic parking assistance system was born. The images are collected...
