Abstract

The invention provides a method for bridge image splicing based on feature points and structure lines. The method comprises the following steps: preparing data; dividing a strip data set; projecting a strip panorama; projecting a panorama of a bridge bottom; processing the image; and outputting the result. The method provided by the invention solves the technical problem that a conventional method in the prior art is excessively dependent on the initial condition or the image texture splicing effect.

Description

technical field [0001] The invention relates to the fields of photogrammetry and computer vision, in particular to a bridge image splicing method based on feature points and structural lines. Background technique [0002] Image mosaic method is one of the important research topics in the fields of digital image processing, photogrammetry and computer vision. It is widely used in geographical monitoring, medical tumor inspection and concrete building disease detection. In the health detection of concrete bridge bottoms, in order to obtain high-resolution bridge bottom images, smart CCD cameras can only cover a small part of the bridge bottom. Therefore, even for a small bridge, it is often necessary to take hundreds of pictures Only then can the bottom information of the entire bridge be obtained well. Faced with such a massive amount of data, how to efficiently stitch these images into a complete panorama of the bridge bottom has become the most critical technology in bridg...
