The system comprises a panoramic camera, a cloud computing server and an intelligent terminal, wherein the panoramic camera comprises an image collection device and a host; the image collection device comprises an image sensing module, an analog-digital conversion module, a digital signal processing module and a USB interface; the host comprises a main control processing module, a distortion recovering module, a viewing angle conversion module, an image splicing module, an image enhancement module and a wireless communication module; and the panoramic camera is connected with the cloud computing server and the intelligent terminal via the wireless communication module. According to the system provided by the invention, the complexity of the video splicing algorithm is greatly simplified, and hardware implementation power consumption is greatly reduced, and the problems image registration, projection conversion and image fusion in the video splicing algorithm are quickly solved. And the problems that the video splicing algorithm is large in calculating amount and poor in instantaneity are solved.

Description

technical field [0001] The invention relates to the field of video splicing, in particular to a panoramic video splicing system based on cloud computing. Background technique [0002] With the development of integrated circuits and computer technology, computer vision and computer image processing technology have developed rapidly, bringing great convenience to people's lives. Panoramic video has been used in different fields because of its wide field of view and high resolution, and can be used in various fields such as parking lot video surveillance, smart home, and augmented reality (AR). [0003] The essence of panoramic video stitching technology is based on image stitching, but due to the time continuity and the requirements of video codec transmission efficiency, video stitching has higher requirements for real-time and correctness. The basic process of image stitching mainly includes: image acquisition, image preprocessing, image registration, projection transformat...

AI Technical Summary

Problems solved by technology

[0005] In terms of computing power, Beijing Times Tuoling Technology uses cloud computing technology to complete panoramic stitching in the cloud in the patent "a processing method and system for panoramic video stitching"; although the use of cloud computing resources improves the stitching speed, but There will be delay problems in the process of uploading videos, which cannot meet real-time performance, and will occupy more system resources

A panoramic video surveillance system based on the ARM platform is used to complete image registration and splicing, which requires a high cost and requires an ARM processor with good performance and memory resources, and there will be a big problem with power consumption
