摘　　要：该论文旨在研究大疆M3E(RTK)无人机航拍影像照片利用Pix4Dmapper软件生成林业正射影像的方法和过程,并对生成的林业正射影像成果进行分析研究,以便推广应用。首先,通过大疆M3E(RTK)无人机规划航线进行航拍获取高分辨率的影像照片数据。然后,将大疆M3E(RTK)无人机采集到的航拍影像照片利用Pix4Dmapper软件进行预处理、校正和拼接,生成无人机航拍影像照片的林业正射影像成果。接下来,利用ArcMap软件对林业正射影像成果进行特征提取和分类,以实现对林地类型和植被信息的智能分析。最后,对生成的林业正射影像成果进行精度评估,并与传统航空影像进行对比分析。The purpose of this paper is to study the method and process of forestry orthophoto image generation by Pix4Dmapper software from aerial images of DJI M3E(RTK)unmanned aerial vehicle,and to analyze and study the forestry orthophoto image generation results for popularization and application.Firstly,aerial photography is carried out through DJI M3E(RTK)UAV planning route to obtain high-resolution image photo data.Then,the aerial images collected by DJI M3E(RTK)UAV are preprocessed,corrected and spliced by Pix4Dmapper software to generate forestry orthophoto images of UAV aerial images.Next,ArcMap software is used to extract and classify the features of forestry orthographic images,so as to realize intelligent analysis of forest land types and vegetation information.Finally,the accuracy of forestry ortho images is evaluated and compared with traditional aerial images.
