Example Embodiment

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0052] In order to improve the speed and efficiency of image stitching processing, in the embodiment of the present invention, each image to be processed is divided into blocks to obtain each block image, and the image of each block image is calculated in parallel according to the preset image processing algorithm. Features, and then stitch each image to be processed according to the image features of each block image to obtain a stitched image. ...

Abstract

The invention relates to the field of digital image processing, and especially relates to an image processing method and device. The image processing method comprises obtaining the number of images tobe processed and the size of each image to be processed, and computing an image segmentation parameter according to the number of the images to be processed and the current operation resource; wherein the current operation resource represents ways of parallel computation supported by the system at present; segmenting each image to be processed according to the image segmentation parameter and thesize of each image to be processed, and obtaining each segmented image; computing image features of all the segmented images in parallel at the same time according to a preset image processing algorithm, and splicing each image to be processed according to the image features of all the segmented image to obtain a spliced image. In this way, the image to be processed is segmented, furthermore allthe segmented images are processed in parallel at the same time, image splicing is achieved, the processing performance of a parallel device can be achieved furthest, and the processing speed and efficiency are increased.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to an image processing method and device. Background technique [0002] Panoramic image stitching technology is used in application scenarios such as video surveillance and panoramic video. Due to the limitations of the shooting angle and viewing angle of the shooting terminal equipment, a single image can only capture a partial scene. It is necessary to use digital image processing technology to stitch multiple images shot from different angles to generate a panoramic image of the shooting environment. In image stitching, it is usually necessary to process thousands or tens of thousands of images, especially in some applications that require high real-time performance such as real-time monitoring of UAVs and panoramic video live broadcasts, it is necessary to stitch many captured images in real time Processing, which puts forward higher requirements on the processing speed ...
