Abstract

The invention provides an image positioning device based on patch characteristic registration, including an image positioning device and a patch registration device connected with the image positioning device. The image positioning device comprises a housing, the housing is internally provided with at least two pick-up heads at intervals, the shooting scopes of the pick-up heads are mutually overlapped, and each pick-up head is electrically connected with a data processing unit. The invention is advantaged in that the image matching precision is relatively high and the matching speed is relatively fast.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an image positioning device based on plaque feature registration. Background technique [0002] Image registration is the process of spatially aligning two or more images of the same scene taken at different times, from different viewpoints, or with different sensors. Its main purpose is to eliminate the geometric deformation caused by different imaging conditions between the reference image and the image to be registered, so that the two have spatial consistency. Image registration algorithms in the prior art can reduce the uncertainty of scene understanding by enhancing the complementarity between information. In the process of image registration, due to the large visual difference in the imaging results of the same scene, it brings great difficulties to the registration, and the existing registration algorithms are not good in terms of accuracy, efficiency, stability and adaptability. ...
