无人机遥感影像在土地确权测绘中的应用

Application of UAV remote sensing image in land right surveying and mapping

为提升土地确权测绘效果,研究无人机遥感影像在土地确权测绘中的应用。采集光线充足的土地遥感影像,结合中值滤波与小波变换预处理土地遥感影像,通过空中三角测量确定影像内各测点坐标,制作数字高程模型数字高程模型(DEM)与数字正射影像(DOM),通过Feature立体测图系统,操作手轮脚盘完成土地确权测绘。实验证明:该方法能精准完成土地确权测绘。

To improve the effectiveness of land ownership surveying and mapping,the application of unmanned aerial vehicle(UAV)remote sensing images in land ownership surveying and mapping was studied.The land remote sensing images with sufficient lighting were collected and combining median filtering and wavelet transform to preprocess the land remote sensing images,the coordinates of each measurement point were calculated based on the images through aerial triangulation to product the digital elevation model(DEM)and digital orthophoto map(DOM).With the Feature stereo mapping system containing the handwheel and foot wheel,the land ownership surveying and mapping was carried out.The experiment proved that this method could accurately complete land ownership surveying and mapping.
