Abstract

The invention discloses a plane coding target and an image splicing system and method using the same. The positioning point distribution pattern of the positioning point is used to determine the coordinates of the central code point and the usual code point in the coding unit coordinate system; the coding value sequences of the coding units are different and unique from each other. The plane coding target can realize large-area coding and positioning functions. The image stitching system of the plane coding target can solve the problems of stitching errors and error accumulation caused by the identification error of the stitching position, and realize the large-scale, high-precision and short-time-consuming two. dimensional image stitching.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a plane coding target and an image stitching system and method using the same. Background technique [0002] In the field of computer vision, visual targets are widely used in visual calibration, object pose measurement, visual navigation and other occasions. At present, the common classification of visual targets are plane targets and stereo targets: stereo targets are mostly used for the calibration and measurement of 3D vision systems. Stereo targets have higher manufacturing requirements, the solution process is more complicated, and it is difficult to achieve large-scale real-time measurement; while plane coding targets It can achieve a wide range of measurement requirements while taking into account the measurement accuracy. At present, the coding targets mainly include circular coding targets, dot distribution coding targets, color coding targets, etc. The circula...
