Method and device for processing panoramic photography

Abstract

The embodiment of the invention provides a method and device for processing panoramic photography. The method comprises steps of: acquiring a picture to be processed and a preset coordinate mapping table, wherein the picture to be processed is formed by horizontally splicing at least two original pictures, and a corresponding relation between the coordinates of pixels in the picture to be processed and coordinates of pixels in a panoramic picture is saved in the preset coordinate mapping table; using the pixels in the panoramic picture as target pixels, and determining source pixels, corresponding to the target pixels, in the picture to be processed by using the preset coordinate mapping table; and performing projection by using the source pixels and obtaining the panoramic picture according to a projection result. The method and the device may decrease calculated amount in a processing process and contribute to real-time online processing of the panoramic picture.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a panoramic shooting processing method and device. Background technique [0002] Panoramic shooting generally refers to a method of taking a horizontal 360-degree and a vertical 180-degree shooting with a certain point as the center, and stitching multiple pictures taken into a panoramic picture and a picture stitching method. [0003] Generally speaking, panoramic shooting may include at least two forms of panoramic image and panoramic video. [0004] Specifically, the processing process of panoramic images is as follows: a single camera is installed on a rotatable bracket, and multiple original pictures are captured by the camera at multiple angles, and then based on the panoramic stitching algorithm, the original pictures are spliced ​​by computer software. , and finally obtain a panoramic image. [0005] Specifically, the processing process of the panoramic video is:...

Problems solved by technology

That is to say, the process of using the panorama stitching algorithm to splicing multiple original pictures is a Multi-Pass calculation process. Realized offline, currently unable to achieve real-time online processing

In addition, considering universality, the computer needs to perform a complete projection calculation for each pixel on the original image, which will inevitably further increase the calculation amount of the processing process and further increase the consumption of computer resources
