Image conversion method and device using calibration reference pattern
TLDR
In this paper, an image of a calibration reference pattern is captured and a plurality of first and second characteristic patterns of the reference pattern are identified, and an image is converted to an output image according to the coordinate conversion relationship.Abstract:
An image conversion method is provided. An image of a calibration reference pattern is captured. A plurality of first and a plurality of second characteristic patterns of the calibration reference pattern are identified. Coordinates of the first and second characteristic patterns in a first view angle coordinate system are obtained, and coordinates of the first and second characteristic patterns in a second view angle coordinate system are obtained, to obtain a coordinate conversion relationship between the first and second view angle coordinate systems. An input image is converted to an output image according to the coordinate conversion relationship.read more

Method for identification of characteristic points of a calibration pattern within a set of candidate points in an image of the calibration pattern
TL;DR: In this article, a method for identifying characteristic points of a calibration pattern within an image of the calibration pattern comprises the steps of, for each candidate point of a set of candidate points derived from the image of calibration pattern: (i) overlaying a template arrangement of template points over the candidate point such that a principal point of the template points coincides with the candidate points, wherein the template arrangement corresponds to the calibration patterns or to a sub-pattern of the calibrated pattern, except the principal point, and (ii) determining a degree of deviation by summing the distances between each template
