摘　　要：常规的模糊信息增强处理方法以图像对比度调整为主,高亮区域过度抑制容易导致细节信息丢失,影响图像模糊信息分析效果。因此,设计了煤矿地质无人机测绘图像模糊信息增强处理方法。正射校正煤矿地质测绘图像模糊信息特征,消除由地形起伏、相机姿态等因素导致的图像几何畸变,使图像具有正确的地理坐标和比例尺,确保图像的空间精度和可用性。多尺度分割煤矿地质测绘图像,保留图像中的重要边缘和细节,将图像分割成具有相似特征的对象或区域,避免噪声与模糊信息对图像的影响。配准煤矿地质无人机测绘图像信息,将不同时间、不同视角或不同传感器获取的图像进行空间对准,再通过去模糊算法实现模糊信息的增强处理。通过对比实验,验证了该方法的图像信息增强处理效果更佳。Conventional methods for enhancing fuzzy information mainly focus on adjusting image contrast,and excessive suppression of highlight areas can easily lead to the loss of detail information,which affects the effectiveness of image fuzzy information analysis.Therefore,a method for enhancing fuzzy information in coal mine geological unmanned aerial vehicle mapping images was designed.Orthorectified coal mine geological mapping images with fuzzy information features to eliminate geometric distortions caused by terrain undulations,camera poses and other factors,ensuring the correct geographic coordinates and scale of the images and guaranteeing their spatial accuracy and usability.Carried out the multi-scale segmentation of coal mine geological mapping images,preserved important edges and details in the image,segmented the image into objects or regions with similar features,and avoided the influence of noise and fuzzy information on the image.The image information of mine geological unmanned aerial vehicle mapping was registered,and the images acquired at different times,from different perspectives or from different sensors were spatially aligned.Then the fuzzy algorithm was used to enhance the fuzzy information.Through comparative experiments,it has been verified that the image information enhancement processing effect of this method is better.
