Embodiment Construction

[0056] The present invention is based on the fault-tolerant matching technology of feature points, a calculation method for continuous seamless splicing of a large number of color or grayscale image frames and computer software implementation thereof. The image stitching method does not need any ground control points, nor any information about the camera position and attitude, but is completely determined according to the correlation of image information between image frames.

[0057] The technical solution of the present invention can adopt computer software technology to realize the automatic operation process. The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments. The embodiment of the present invention provides an anti-subtitle interference image seamless automatic splicing method including the following steps. For the flow chart, see figure 1 :

Abstract

The invention provides a seamless automatic image splicing method resistant to subtitle interference. By means of the method, video frames (such as video frames or multiple continuous images shot by a continuously moving or rotating camera) in a varied scene can be continuously spliced to form a complete image. Camera position and pose and scene control point information, proportion and perspective transformation are not required, and rotation of videos (or image sequences) at any angle is not required to be considered, full-automatic color video image seamless splicing is achieved, various high-saliency associated information among the image sequences is fully utilized to perform automatic splicing calculation, the splicing accuracy of adjacent frames can reach to sub pixel, and a parallel technology can be utilized to improve the splicing speed in multiples.

Description

technical field [0001] The invention belongs to the technical field of computer vision image processing, and in particular relates to a fully automatic video image seamless mosaic technology which is resistant to subtitle interference. Background technique [0002] Automatic image stitching technology has a wide range of needs and applications in remote sensing surveying, military reconnaissance, space exploration (such as image stitching on the surface of the moon and Mars), 360° panoramic image generation, and automatic stitching of UAV remote sensing images. Once there is rotation in the traditional image stitching process, interference factors such as scale and illumination transformation often require manual participation, which is time-consuming and laborious, with low precision and difficult to automate. Especially in the military field, there is often no GPS available, and the camera attitude and position cannot be accurately known. There is an urgent need for a real...
