图像配准方法及其装置以及图像拼接方法及其装置
摘要：
本发明公开了图像配准方法、图像配准装置、图像拼接方法和图像拼接装置。该图像配准方法包括：步骤S100：对第一图像和第二图像进行文字识别，其中该第一图像和该第二图像包含文字；步骤S200：基于文字识别结果生成候选匹配对；步骤S300：在该候选匹配对中选择自洽的候选匹配对并且根据该自洽的候选匹配对生成该第二图像到该第一图像的几何变换；以及步骤S400：根据该几何变换，将该第二图像映射到该第一图像的坐标系中。上述图像配准方法和其对应装置计算量小、配准准确。因为配准过程的计算量小、结果准确，上述图像拼接方法和其对应装置也在较小计算量的前提下，能够取得较好拼接效果。
摘要（英）：

The invention discloses an image registration method, an image registration device, an image splicing method and an image splicing device. The image registration method comprises steps of performing character recognition on a first image and a second image, wherein the first image and the second image contain characters, generating a candidate matching pairs based on the character recognition result, choosing a self-consistent candidate matching pair from the candidate matching pairs and generating a geometry transformation from the second image to the first image according to the self-consistent candidate matching pair, and mapping the second image into the coordinate system of the first image according to the geometry transformation. The image registration method and the image registration device are small in calculation amount and accurate in registration, and because of that, the image splicing method and the image splicing device can achieve a better splicing effect under the premise that the calculation amount is small.
