A vehicle-mounted panoramic imaging assistance method and system thereof

Abstract

The invention relates to an auxiliary method for vehicle-mounted panoramic imaging, which includes a preset normal splicing model and a close-up splicing model, which are stored in a storage module; collecting distance information and image information outside the vehicle body; judging whether there is an object, and if so, locally using the close-up The splicing model performs image splicing on the external environment of the vehicle body, otherwise, uses the normal splicing model to perform image splicing on the external environment of the vehicle body; and displays the resulting vehicle panorama on the image display module. The invention also proposes a vehicle-mounted panoramic imaging auxiliary system. Compared with the prior art, the present invention has the following advantages: an auxiliary system with a distance measuring device is designed, which can change the splicing model according to the objects around the vehicle body obtained by the distance measuring device, and solves the problem that if objects in the overlap area of ​​the viewing area Close to the car body will cause serious distortion of stitching, which improves the effect of panoramic image stitching. Collision warning, which can be displayed on the display module and / or alarm through the voice system, improves driving safety.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle-mounted panoramic imaging auxiliary method and system thereof. Background technique [0002] With the development of automotive electronics and computer vision, the equipment for assisting drivers in vehicle control is becoming more and more developed, and various sensors are continuously added to automotive electronics. As a common automotive electronics, reversing radar uses the principle of ultrasonic ranging to collect the distance between objects near the rear of the car and the car body, and uses display devices or sound devices to prompt the driver. The vehicle-mounted panoramic imaging system uses cameras around the car body to collect images in all directions of the car body, and then stitches them together according to the camera's own parameters and installation parameters to obtain a 360-degree panoramic image around the car body. The above application...
