Light field image correction method, computer readable storage medium, and electronic terminal

Abstract

A light field image correction method, a computer readable storage medium, and an electronic terminal are provided. The invention projects the three-dimensional scene in the world coordinate system tothe current light field image in the current camera coordinate system and the ideal light field image in the ideal camera coordinate system, takes the current light field image as an input and takesthe ideal light field image as an output, and calculates a transformation matrix corrected from the current light field image to the ideal light field image. The image of each light field in ideal coordinate system has only horizontal parallax, there is only vertical parallax in the same image column, and the baselines between adjacent images are equal, which provides great convenience for pixel matching searching process in computer vision applications such as depth estimation and image matching; rays can be periodically sampled so that multi-camera array images can be efficiently applied torelated light field rendering algorithms.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular to a method for correcting light field images, a computer-readable storage medium, and an electronic terminal. Background technique [0002] As an electromagnetic field distributed in space, light has various properties such as amplitude, phase, and wavelength, and helps humans perceive the brightness, position, and color of objects. However, traditional optical imaging intelligently captures the projected intensity of light radiation on a two-dimensional plane, while losing the three-dimensional shape information of the target. The acquisition of light field information is to obtain the complete distribution of optical radiation, and calculate the required image through data processing methods such as transformation and integration. Light field imaging refers to the process of collecting and processing the light field into an image. Light field imaging is a computational...
