Comparison of color consistency processing methods for UAV aerial photography images
摘要
Abstract
Unmanned aerial vehicle(UAV)aerial photography is a low-cost and high-efficiency method for acquiring sur-face information,capable of addressing application needs such as disaster response and dynamic monitoring.To meet the requirement of acquiring large-scale data within a short space domain window,multiple flights and various models of UAVs were employed for aerial photography.However,such aerial photography results suffer from color inconsistencies,impact-ing processing efficiency and output quality.To address this issue,three methods,namely histogram adjustment,batch pro-cessing for light uniformity,and aerial image color transfer,were adopted to achieve color consistency in the images.A com-parative evaluation of the color uniformity-adjusted images was conducted through visual comparison and quantitative analy-sis.The comparison reveals that after histogram adjustment,images suffer minimal loss of color information but have poor overall quality due to manual operation constraints;images processed through batch processing for light uniformity appear overly uniform in color,losing their uniqueness and variability;aerial image color transfer achieves different color unifor-mity parameters for different regions,unifying the overall effect while preserving the original color differences in the images.The results can serve as a reference for color uniformity adjustment in other aerial photography data.关键词
