Embedded panoramic display device and method served for automobile safe driving

Abstract

The invention provides an embedded panoramic display device and method served for automobile safe driving. The embedded panoramic display device comprises an ultra-wide field camera, a video collecting card, a panoramic display CPU (central processing unit), a memory and a display; analogue signals collected by the ultra-wide field camera are converted into digital signals through the video collecting card; the digital signals are transmitted to an image processing module consisting of the panoramic display CPU and the memory to carry out image correction; and a corrected image and an automobile top view are spliced in an image processing module, and are output on the display. With the adoption of the embedded panoramic display device and method, provided by the invention, scenes around an automobile body are directly displayed through a display screen; when an automobile normally drives, panoramic assistance is provided for a driver driving under a crowded road condition; and meanwhile, a multi-vision video switching function is provided, more abundant and clear images in a dead area can be provided for a condition that the automobile drives from a ring road to a main road in an inclined manner or special road conditions, and the effective scheme of solving the potential safety hazards because the vision range of the driver is limited can be provided.

Description

technical field [0001] The invention relates to an embedded panoramic display device and method, which provide rich and clear images for vehicles traveling on special road conditions such as dense roads, high-risk intersections, and blocked intersections. Background technique [0002] With the development of the economy and the continuous improvement of people's material living standards, the number of private cars in my country exceeded 70 million in July 2011 (data from http: / / www.chinadaily.com.cn). Not wide urban roads become more congested, and with the addition of a large number of inexperienced drivers every year, the safety hazards of driving are exacerbated, followed by frequent traffic accidents, between cars, cars Scratches with other vehicles are not uncommon. At present, the road condition feedback tools for assisting drivers are mainly focused on the central, left and right rearview mirrors and parking assistance systems (mainly used for reversing assistance). ...

Problems solved by technology

However, due to the high installation position of the camera, it is impossible to capture close-up scenes around the car body, and there are still visual blind spots, and the top view of the car has not been able to establish a connection with its own model, and cannot provide the distance between the obstacles in the picture and the car body. A set of independent equipment, not easy to integrate with existing systems

[0007] The paper "Research on the Application of Video Mosaic Technology in Visual Reversing Radar" published in the journal "Computer Knowledge and Technology" designed a video mosaic algorithm and a PC / 104-based hardware system to splicing two video channels into one video, realizing The application requirements for panoramic visual reversing do not involve safety assistance for cars driving in dense roads, key road sections, high-risk intersections, dense buildings and other situations where the line of sight is obstructed
