[0008] 1. Adjacent image stitching

[0009] (1) Color space transformation

[0010] Color space is the spatial expression of color, including various types, such as RGB, HSI and YUV. Color spaces, such as RGB, HSI and YUV, concretize abstract and subjective visual perception into positions or vectors in three-dimensional space, making various color images and color devices All color characteristics can be visualized and become an important tool for color research.

[0011] In order to overcome the uneven and unintuitive shortcomings of the RGB color space, color space transformation methods are mostly used in color image processing to convert the RGB color space into other color spaces that are more in line with the color visual characteristics, and then do further processing. And convert the processed result back to RGB color space. The conversion process of color space requires a lot of calculations, which has a great impact on the real-time performance of color image proc...

Abstract

Since a true color image has richer visual information, how to improve the efficiency of a mosaics algorithm needs to be specially considered. On the basis of the characteristic analysis of RGB (Red, Green and Blue) and HSI (Hue-Saturation-Intensity) color spaces, the invention provides a method for measuring pixel color similarity according to the chromaticity and saturability characteristics of a color, and simultaneously provides a characteristic template extraction method used in color image matching. Through the brightness relationship analysis of an overlapping region between two color images to be mosaic, a brightness change function between images is established, color difference between two images can be globally regulated, mosaic seams can be eliminated, and a visual effect is enhanced.

Description

technical field [0001] Based on the characteristic analysis of RGB and HSI color spaces, the present invention proposes a method for measuring pixel color similarity according to color chroma and saturation features, and simultaneously proposes a feature template extraction for color image matching method, and finally realize the rapid and seamless stitching of UAV remote sensing images. Background technique [0002] UAV is an unmanned aircraft, which is an unmanned aerial vehicle controlled by radio remote control equipment or its own program control device. UAVs are generally equipped with autopilots, program control systems, remote control and telemetry systems, automatic navigation systems, automatic landing systems, etc., through these systems to achieve long-distance control flight. Since the 1980s, with the rapid development of computer technology, communication technology and sensor technology, the performance of unmanned aerial vehicles has been continuously improv...
