Real-time panorama generation realization system and method based on Spark and OpenCV

Abstract

The invention provides a real-time panorama generation realization system and method based on Spark and OpenCV, and belongs to the field of computer vision, and the system comprises a video collectionmodule, a video caching module, a video processing module, a panorama picture storage module, and a panorama picture analysis module. The method comprises the following steps: 1) starting a holder, and driving a camera to rotate for multiple circles at different elevation angles to acquire videos; 2) converting the video stream into a frame by using OpenCV; 3) converting the key value pair of each frame of image, and sending the converted key value pair to a kafka server for caching; 4) enabling the Spark to obtain the cached image from the kafka server; 5) enabling the Spark to operate a panoramic video stitching algorithm based on OpenCV, and perform multi-circle stitching on the acquired images to generate a panoramic picture; and 6) storing the spliced panoramic image into an HDFS forcalling of a specific application. According to the invention, some scenes with high real-time requirements, such as scenic spot fire prevention, can be satisfied.

Description

technical field [0001] The invention relates to a system and method for realizing real-time generation of panoramas based on Spark and OpenCV, belonging to the field of computer vision. Background technique [0002] At present, panoramic video stitching technology has been widely used in various aspects of production and life, such as virtual reality, scenic spot fire protection, and satellite images. However, there are certain problems at present, such as if the amount of data is too large If this is the case, the time to process the video and generate the panoramic image will be very long, and it cannot be generated in real time, which makes it difficult to meet some scenes that require high real-time performance, such as the prevention of fire in scenic spots, so it is necessary to A technology capable of quickly generating panorama pictures based on a pan-tilt camera, so it is necessary to design a real-time panorama generation system and method to realize the real-time ...
