Laser ranging auxiliary splicing system and image splicing method

Abstract

The invention relates to a laser ranging auxiliary splicing system and an image splicing method. The system comprises a front-end acquisition module, a switch and a rear-end processing system, the front-end processing system comprises five cameras which are identical in performance and have imaging angles of 30 degrees. Laser range finders parallel to the optical axes of the five cameras are installed at the tops of the two outermost cameras, the cameras are all communicated with a rear-end processing system through a connection switch, and the rear-end processing system comprises a computer provided with splicing system software. According to the image splicing method, through the steps of reasonably setting deflection angles of five cameras, ensuring enough object distance through calculation, obtaining a coverage area through calculation and the like, targets with weak textures or repeated textures can be effectively spliced without using a complex splicing algorithm, and an ultrahigh-resolution large-view-field image is obtained.

Description

[0001] (1) Technical field [0002] The invention relates to the field of image processing, in particular to a laser ranging auxiliary stitching system and an image stitching method. [0003] (2) Background technology [0004] For murals, large calligraphy and paintings, textiles and other large planar objects with high aspect ratio, it is necessary to use ultra-high resolution and large field of view images when collecting image information, but limited by hardware technology, a single camera cannot achieve it. [0005] With the development of computer and image processing technology, fisheye lens system, rotating splicing and multi-camera systems have been widely promoted as the main means of large field of view panoramic imaging. The disadvantage of the fisheye lens solution is that the distortion is very serious. The closer to the edge of the image, there is a perspective transformation with a larger angle. Therefore, the closer to the edge, the fewer pixels are covered per...

Problems solved by technology

The disadvantage of the fisheye lens solution is that the distortion is very serious. The closer to the edge of the image, there is a perspective transformation with a larger angle. Therefore, the closer to the edge, the fewer pixels are covered per angle, resulting in serious uneven resolution. ;Single-camera rotation stitching, because its core principle is to use multiple images collected by ordinary lenses to stitch together an image collected by a fisheye lens, so it inherits the shortcomings of the fisheye lens, the closer to the edge of the stitched image, there is The perspective transformation of the larger angle; the multi-camera system cannot correctly register the images due to the existence of parallax

Especially for objects with repeated textures or less texture information, it is easy to cause stitching errors
