Abstract

The embodiment of the invention discloses a fisheye panoramic image synthesis processing method and device. The fisheye panoramic image synthesis processing method comprises the steps of acquiring first test fisheye images of a chessboard target, processing the first test fisheye images according to a Zhengyou Zhang calibration algorithm to acquire intrinsic parameters of a fisheye camera; acquiring second test fisheye images of an annular target, and acquiring extrinsic parameters of the fisheye camera according to an iterative closest point algorithm; acquiring fisheye images to be synthesized, acquiring a corresponding relation between pixel coordinates of the fisheye images to be synthesized and pixel coordinates of fisheye image nonstandard Thoby expanded image according to the intrinsic parameters and the extrinsic parameters; processing the fisheye images to be synthesized according to the corresponding relation to acquire a synthesized panoramic image. The corresponding relation between the pixel coordinates of the fisheye images to be synthesized and pixel coordinates of the panoramic image can be acquired through acquiring the intrinsic parameters and the extrinsic parameters of the fisheye camera, thereby being convenient for processing according to the corresponding relation to acquire the synthesized panoramic image. The original images are photographed simply, the image synthesizing process is high in automation degree, and real-time image synthesis can be performed.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a fisheye panoramic image synthesis processing method and device. Background technique [0002] Fisheye image synthesis technology is an image-based panorama synthesis processing technology developed in recent years. The characteristic of this technology is that its processing has nothing to do with the complexity of the scene, and it can achieve photo-level realism. Using this technology, the user first captures a group of fisheye images of a scene to be synthesized through a fisheye camera, and then performs synthesis processing on the fisheye images to be synthesized to obtain the final panoramic image. [0003] At present, there are many methods for processing panoramic images, such as the processing of cylindrical panoramas. The user shoots multiple overlapping images in the horizontal direction at different angles at the same position, and synthe...
