Abstract

The invention discloses a long-exposure panoramic image photographing device. The device comprises: an image acquisition module used for acquiring images collected by a mobile terminal viewfinder in a timing way when receiving a long-exposure photographing instruction; an image projection module used for projecting the acquired images to a preset projection space to form corresponding projection images; a registration and fusion module used for carrying out position registration and pixel fusion on subsequent projection images having a plurality of visual angles and meeting preset projection conditions with a reference projection image one by one to form new reference projection images, until all of the acquired subsequent projection images are traversed; and a reverse projection module used for reversely projecting the output projection images to a coordinate space for the mobile terminal viewfinder to collect the images to generate a long-exposure panoramic image. The invention further discloses a long-exposure panoramic image photographing method. By adopting the long-exposure panoramic image photographing device and method disclosed by the invention, the adaptability of a mobile terminal to jitter in a long-exposure photographing mode is reinforced, and the long-exposure photographing function of the mobile terminal is used more conveniently.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a long-exposure panoramic image shooting device and method. Background technique [0002] With the development of electronic technology, mobile terminals such as smart phones and digital cameras on the market generally have a long-exposure shooting function. Environment, often used to shoot running water, nebula star trails, road light trails at night, etc., can shoot amazing space-time images. [0003] The existing long-exposure shooting method is to use a tripod or other fixing device to keep the mobile terminal with a camera fixed, and then perform exposure shooting. Since this shooting method requires the photographer to carry the fixing device with him, the mobile terminal cannot be shaken for a long time. However, when the mobile terminal user is shooting outdoors, it is very inconvenient to carry a larger and heavier fixing device, resulting in The long-...
