Abstract

The present invention provides an image calibrating, composing and depth rebuilding method of a panoramic fish-eye camera comprising the following steps of: establishing a panoramic optical targeting space; using the panoramic fish-eye camera for shooting the panoramic optical targeting space's panoramic image; establishing a internal parameter calibrating model for the panoramic fish-eye camera; establishing a image stitching parameter model and a space depth transforming parameter model of the panoramic image and the panoramic optical targeting space; and using the internal parameter calibrating model, the image stitching model, the depth transforming parameter model to calibrate the panoramic image for generating a 3D panoramic image. Compared to the prior art, the present invention can optimize the calibrating parameters by accumulating all the camera data and executing machine learning for increasing computing efficiency.

Description

technical field [0001] The present invention relates to the technical field of optical image processing, more specifically, relates to a panoramic optical target space captured by a panoramic fisheye camera to obtain a scene synthesis parameter model (that is, an external correction parameter model) and a spatial depth of field conversion parameter model, A panoramic fisheye camera image correction, synthesis and field depth reconstruction method and its system are combined with an internal correction parameter of the panoramic fisheye camera to perform panoramic image correction. Background technique [0002] Since the advent of the camera, people have begun to use images to record life moments or major events of the times. Photography technology and equipment have also evolved from low-quality black-and-white photos to high-quality and high-saturation color photos, and even high-speed cameras that can shoot two billion frames per second. The visual effects are not limited...
