Problems solved by technology

[0004] 1 In order to obtain a higher dynamic range, the exposure time of different cameras is different, so each image has its own dynamic range, and it is difficult to directly stitch
[0005] 2 The amount of ultra-high pixel data is very large. If it is all read into the display, it will consume a lot of memory resources, and if network transmission is required, it will also occupy a large bandwidth.

Abstract

The invention provides a method for reconstructing and displaying a billion-pixel high dynamic range image. The method comprises the step of acquiring a plurality of million-pixel level sub-images, the step of splicing the acquired sub-images into a billion-pixel spherical surface image and adjusting the dynamic range of the spherical surface image, and the step of displaying the spliced image to a user in an interactive mode according to the demands of the user. According to the method, a panoramic image with integral details and different dynamic ranges can be acquired, and the user can integrally take out and display the concerned partial image conveniently.

Description

technical field [0001] The invention belongs to the field of computer vision, and in particular relates to a method for reconstructing and displaying a billion-pixel high dynamic range image. Background technique [0002] With the continuous improvement of computer computing power and continuous improvement of shooting equipment, people hope to obtain panoramic images without losing detailed information. The resolution, dynamic range, and field of view of a single camera are often mutually restricted. Collecting through multiple cameras and stitching the obtained images can break through the constraints of a single camera and stitch together to obtain ultra-high-pixel images. [0003] However, in the prior art, super high pixel image stitching has the following difficulties: [0004] 1 In order to obtain a higher dynamic range, the exposure time of different cameras is different, so each image has its own dynamic range, and it is difficult to directly stitch. [0005] 2 Th...
