Technical field
The invention belongs to image processing field, specifically the real-time joining method of a kind of multi-functional panoramic video.
Background technology
Panoramic video splicing relates to the technology such as computer vision, computer graphics, Digital Image Processing and some mathematical tools.Panorama sketch can express complete ambient condition information, is equivalent to observer and turns around from a fixed view to surrounding the scene that can see.
Full-view video image splicing the mutual registration of each consecutive frame image in one section of video is generated the panorama sketch that a width comprises all information of video sequence.Panorama brings brand-new real scene sense and interactively impression.It can be widely used in three-dimensional electronic commercial affairs, as the online field such as the displaying of real estate building, virtual tourism, virtual education, this technology also has important application in the acquisition etc. of the observation of large area static scene, virtual reality, video frequency searching and high-definition picture.
For real-time video panorama mosaic technology, one of main difficulty is the requirement of real-time.As everyone knows, normal video frame per second is generally 25 ~ 30FPS, this means at least to synthesize a width panoramic frame in 0.04 second, and existing static panorama image generation algorithm all cannot accomplish this point, therefore cannot directly apply to Video Composition.And for the innovatory algorithm of static panorama picture quality also because amount of calculation too greatly cannot for the treatment of frame of video.
The research of the real-time splicing of regarding three-dimensional panoramic video is in recent years fast-developing, many research is expanded to video-splicing method both at home and abroad, many research institutions, enterprise have all dropped into a large amount of funds and manpower splices in real time at panoramic video, three-dimensional sight build correlation theory and engineer applied in.
Current 3D panoramic video joining method has very large shortcoming in the rapidity sense of reality, real-time, there is the problems such as the not high splicing effect of real-time speed is undesirable.Panorama is at present by high commercial, and along with the progress of computer technology, the expectation of people to panorama is more and more higher, therefore, is necessary according to actual application background, the video-splicing method of the more accurate quick and convenient practicality of further research and probe.
Summary of the invention
The present invention proposes the real-time joining method of a kind of multi-functional panoramic video.Mainly under the real-time of panoramic video generation and the demand of accuracy, a kind of brand-new settling mode is proposed, namely under motion state, real-time generation with the 3D full-view video image of positional information, the present invention can realize three-dimensional panoramic video frame with the Auto-matching of the 3DGIS data of latitude and longitude coordinates and Seamless integration-.
The present invention proposes the real-time joining method of a kind of multi-functional panoramic video, comprising: obtain three-dimensional video-frequency flow data, gps data, INS data and 3DGIS data that multiple video camera is taken different angles; Judge that whether GPS and the INS time is synchronous, whether whether synchronous and each road, GPS and GIS position video is synchronous; Complete the parsing of video data and spatial positional information, compression, the work of analysis pick up and store; Data calibration is carried out to each circuit-switched data, by video data, gps data, GIS data, the unified process of INS data integrated, extracts the space characteristics point with latitude and longitude information; Utilize spatial coordinate accurate profile Point matching pair, automatic selection of optimal splicing parameter, splices in real time image and merges.
Data acquisition equipment of the present invention adopts a kind of novel layout structure to be fixed, the automatic selection of optimal of image characteristic point, video matching frame, image mosaic transformation parameter only need be carried out at former frames of video camera synchronous acquisition, corrected by feature point pairs spatial coordinated information simultaneously, obtain optimum splicing parameter, then this optimum splicing parameter is used in the splicing function of subsequent video frame, realizes the dynamically splicing in real time of three-dimensional panoramic video stream.
The real-time joining method of the multi-functional panoramic video of one that the present invention proposes has following beneficial effect: 1. the present invention can generate the three-dimensional panoramic video with elaborate position mark efficiently, in real time.2. the present invention is by the pair correlation of feature point pairs to solid space coordinate, improves the precision of splicing.
