Multi-lens sensor-based image fusion method

Abstract

The invention provides a multi-lens sensor-based image fusion method, and belongs to the field of image synthesis. The method includes: acquiring multiple images on the basis of a multi-lens sensor; constructing coordinate parameters according to a relative position relationship of the multi-lens sensor, and completing coordinate transformation, which is of image points on a target object in the multiple images, from plane space and to three-dimensional space, according to the coordinate parameters to obtain transformed images; extracting contour information of the target object according to classical collinearity equations, orientation elements in the multi-lens sensor and attribute values of feature points; and splicing the multiple images according to the contour information to obtain a spliced image. Through above processing, the five images can be spliced into the one image, and relative space relationships between different regions in the target object can be obtained on the basis of the obtained image to establish a strict spatial mathematical model of a multi-lens camera. On the basis of the technology, a user can carry out fast unmanned-aerial-vehicle line inspection of transmission lines, fuse the images collected by multiple lenses, and establish a real geographical environment scene.

Description

technical field [0001] The invention belongs to the field of image synthesis, in particular to an image fusion method based on a multi-lens sensor. Background technique [0002] At present, due to the high-altitude, long-distance, fast and self-operation capabilities of the UAV system, it is widely used in the rapid inspection of power grid lines. However, most of the current UAV systems are equipped with a single ordinary camera. When UAVs are used to take pictures along the grid line towers, only one photo at a single moment can be obtained. [0003] In order to obtain the image data of different angles and details of the tower, it is necessary to use the UAV to take multiple shots at different heights. times, thus reducing the work efficiency of line patrol operations. Contents of the invention [0004] In order to solve the shortcomings and deficiencies in the prior art, the present invention provides an image fusion method for synthesizing a plurality of images so a...
