Method for achieving interactive panoramic video stream map

Abstract

The invention discloses a method for achieving an interactive panoramic video stream map, and the method comprises the steps: employing a high-definition camera, and employing six CCDs with fixed inclined angles for achieving nearly 100% omnibearing spherical imaging; calibrating the camera, and carrying out the collection of panoramic video data after the conversion between coordinate systems in a process of three-dimensional reconstruction; carrying out the preprocessing of collected data after collection, reconstructing a more real three-dimensional scene, importing the three-dimensional scene to video splicing software for splicing, and enabling final panoramic video stream data to achieve the best visual effect; finally carrying out the issuing at a Flash format. The panoramic video stream map based on continuous scenes can effectively solve a problem that the user experience of a conventional panoramic map based independent scene image groups is not good during switching of different scenes because the video stream is continuous.

Description

technical field [0001] The invention relates to the field of panoramic video, in particular to a method for realizing an interactive panoramic video stream map. Background technique [0002] With the progress of the times, people's requirements for geographic information results no longer simply stay on symbols, words and numbers, but rise to the height of spatial information. People not only hope to arrive at the destination accurately, but also want to see the real scene and enjoy an excellent user experience. The use of 360-degree panoramic video streaming maps will gradually move from macro to micro, from abstract to concrete, truly realizing the browsing of maps from a human perspective, and providing users with map services that are more realistic, accurate, and rich in picture details. [0003] Panoramic video streaming map directly reflects the original appearance of space objects and natural environment with high-definition video images. It contains traditional tar...

AI Technical Summary

Problems solved by technology

Both the 360-degree panoramic video stream and the ordinary map can be used as a map, but the ordinary map has no three-dimensional effect due to the limited viewing angle range, while the 360-degree panoramic video stream not only has a 360-degree panoramic view, but also can bring a three-dimensional stereoscopic feeling, allowing observers can immerse themselves in

The three-dimensional and immersive sense of 3D modeling is undoubtedly stronger than that of 360-degree panorama, but the production of 3D modeling requires a lot of manpower and material resources, and there will be trade-offs in the collection of building models during the production process

[0006] 1. Time synchronization of data collection: How to make 6 cameras shoot synchronously, and how to record 6 cameras and GPS receiver signals synchronously

[0007] 2. The problem of video splicing processing efficiency: the amount of collected high-definition video data is huge, how to efficiently complete the splicing work under the premise of ensuring data quality; at the same time, because the captured data may contain personal privacy, information related to state secrets or government security, It is necessary to process these image information, and the workload of this task is also huge

[0008] 3. The user experience problem of achievement publishing: the data volume of the panorama video results after splicing is also very large, how to optimize the network and the client, and select the appropriate network publishing format to publish smoothly on the basis of satisfying users with ordinary bandwidth Play high-definition video panorama to improve user experience
