Embodiment Construction

[0016] A kind of intelligent panorama generation method based on two fisheye images described in the present invention first needs to shoot two fisheye images, and its shooting device and shooting method can be found in figure 1 . The two fisheye images are taken back to back at the same node, wherein 101 is a digital camera with a fisheye lens installed, 102 is a special pan-tilt for panoramic shooting, 103 is a tripod supporting the camera, and 104 is a node. Fix the tripod 103 earlier when shooting, put on the cloud platform 102 (in order to ensure the accuracy of shooting, it is best to use a special panorama platform), adjust the level of the cloud platform 102, and the digital camera 101 with a fisheye lens is fixed on the cloud platform 102 on. Note that the effective angle of view of the fisheye lens used must be greater than 180 degrees, so that the scenes captured by the two fisheye pictures will partially overlap, so as to facilitate the automatic stitching positio...

Abstract

The intelligent panorama creating process based on two fish-eye images includes pre-treatment of fish-eye images, creating spatial model, optimizing the matching parameters and creating panorama. Owing to the theoretically perfect spatial model, model free dimension number for the matching parameter optimizing process reduced from 8 to 4 and the exhaustive search algorithm capable of avoiding trapping in local minimum, the present invention can find fast the optimal matching parameters, and has the advantages of fast matching speed, high matching precision and high image quality. Furthermore,the present invention has automatic pre-treatment of fish-eye images and automatic matching process, so that it may be usd in automatic matching treatment of great amount of fish-eye images.

Description

technical field [0001] The invention relates to a panorama generating method based on two fisheye images. Through this method, the user only needs to use a digital camera with a fisheye lens to take two fisheye pictures as original materials, and the full spherical panoramic image can be quickly generated. Background technique [0002] Panoramic technology is an image-based rendering technology developed in recent years. The feature of this technology is that its rendering has nothing to do with the complexity of the scene, and it can achieve photorealism. Using this technology, the user first takes a group of sample images of a certain scene through photographic equipment, and then stitches the sample images together to obtain the final panoramic image. Through the interactive panoramic image player, users can realize any virtual roaming of the scene with a 360-degree perspective. [0003] According to different spatial models of panoramic image data mapping, panoramas ca...
