Method, device and equipment for generating panorama in real time

Abstract

The invention provides a method for generating a panorama in real time. The method comprises the following steps of calibrating internal parameters of a camera, establishing a coordinate system and creating a cylindrical projective plane; acquiring video images; projecting the video images onto the cylindrical projective plane according to a projection computation sequence to create the panorama. The invention also provides a device for generating the panorama in real time. According to the scheme provided by the embodiment of invention, the panorama can be generated and previewed in real time by utilizing video streaming, and the method and the device have the characteristics of simple operation and low requirement on hardware. According to the scheme provided by the invention, a panoramic picture can be generated and previewed in real time on mobile equipment such as the current mainstream mobile phones.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, the present invention relates to a method, device and equipment for real-time generation of panoramas. Background technique [0002] The field of view that can be captured by the shooting unit of a digital imaging device is usually much smaller than the field of view of the human eye. Panorama generation technology is a subject of extensive research in the fields of image processing and computer vision. It has important applications in many fields such as large-scale scene display, photography, film and television production, sports training, and even military affairs. [0003] For example, the application with publication number CN 102469259A in the prior art provides a panoramic image generating device and a panoramic image generating method. When a panoramic image is generated from a plurality of still images constituting a moving image, an extremely horizontal...

Problems solved by technology

[0007] After analysis, it is found that the scheme of realizing panoramic images based on feature point matching has a shortcoming in that it requires high shooting skills of the photographer, and a slight deviation in movement will have a great impact on the quality of the panorama

In addition, due to the post-processing method, the shooting result cannot be previewed in real time, and it is not convenient for the photographer to control the shooting process

[0008] The existing solutions for realizing panoramic images based on hardware positioning have the disadvantages of the accuracy and high cost of hardware devices

If the accuracy is not enough, it is difficult to obtain high-quality results, and the use of high-precision hardware equipment will bring about a significant increase in cost

In addition, on the current low-end mobile devices, many of them are not equipped with related hardware positioning devices, which greatly restricts the use of such methods
