Problems solved by technology

[0003] However, due to the limitations of the current hardware solutions used by panoramic camera equipment, products that use DSP for image processing have poor human-computer interaction performance, and there are few adjustable parameters in the process of shooting and outputting images, which cannot meet the requirements for shooting, processing and stitching effects. need
Panoramic camera devices based on general-purpose CPUs (including desktop, mobile or embedded CPUs) have relatively many configurable parameters and richer functions in the process of shooting, processing and stitching, but are limited by CPU processing power, and the stitching efficiency is low. Long processing time and poor real-time performance

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and tool for generating panoramic images based on hardware acceleration. Background technique [0002] Currently, there are two widely used methods for generating panorama pictures. One is to use software post-processing to stitch multiple images taken by the camera; the other is to use integrated equipment, such as panoramic camera equipment, to directly capture and generate panorama pictures. The former mainly relies on post-production image processing software, such as Photoshop, etc., and cannot obtain the shooting results in time, and must be processed by a computer after the shooting is completed; the latter mainly relies on panoramic camera equipment, and can obtain the shooting results in time. [0003] However, due to the limitations of the current hardware solutions used by panoramic camera equipment, products that use DSP for image processing have poo...
