A panoramic imaging method based on a single camera and its device, the device includes a sequentially electrically connected camera, a distortion correction module, an image splicing update module, an image conversion module, and an image processing module, and the storage module is electrically connected to the image splicing update module . Compared with the prior art, the present invention only adopts one camera, while the prior art adopts 4 cameras; when the storage module receives the new global image, the storage module will update the old global image with the new global image, update The speed is fast, the storage space is reduced, and the operating efficiency is improved. It can not only display the surrounding images of the vehicle but also the images under the vehicle. It makes the reversing process more vivid, the driver's operation is more convenient and safer, and at the same time, it further reduces the difficulty of the driver's reversing, making the panoramic reversing image more accurate, with simple structure, low cost, small interference, small error, and easy to use Convenience, improved reversing safety factor and other advantages.
Description
technical field [0001] The invention relates to the technical field of vehicle-mounted auxiliary reversing systems, in particular to a single-camera-based panoramic imaging method and device thereof. Background technique [0002] In the field of car assisted driving, in order to facilitate the driver to reversing, the methods generally adopted include car radar and rear-view camera, but these technologies can only realize the display of rear-view images when the car is reversing, and cannot meet the requirements of 360-degree panoramic images. In recent years, with the gradual popularization of panoramic image technology, in order to achieve 360-degree panoramic image reversing, people add multiple cameras to the rear-view camera parking system, such as front-view camera, left-view camera, right-view camera and rear-view camera. And through the image stitching technology, a panoramic reversing image can be generated, which can eliminate blind spots, reduce car accidents, and...
