Abstract

The invention provides a distorted image correction method and a distorted image positioning method that can be used for real-time correction of fisheye images. The distorted image correction method includes the steps of: (1) determining correction parameters; and (2) determining a correction algorithm according to the correction parameters; wherein step (1) further includes the steps of: (11) determining the position and contour of the multipath distortion image ; and (12) determining a correction factor for the distorted image. The distorted image correction method uses a four-point positioning method to accurately locate the position and contour of the distorted image, so as to ensure the accuracy and effectiveness of the distorted image correction method.

Description

technical field [0001] The present invention relates to an image correction technology in the field of photography and imaging, and more specifically relates to a distorted image correction method and its positioning method. Background technique [0002] Photography and videography occupy a very important position in the daily life and work of modern people, and have become an indispensable part of people's life, work and life. [0003] People are used to using electronic devices with photography and camera functions to record every bit of life. People like and need such a tool to record some memorable moments, a period of time, and a scene in life such as the growth of children, the gathering of relatives and friends, and beautiful scenery. [0004] As people's demands for photography and videography technology are increasingly diversified, various photography and videography lenses are used and loved by people. For example, in order to enable photography and camera equip...
