Abstract: The multi-angle real-life proofed photos of the national land survey have multiple characteristics:high resolution, rich layers, and clear sections. The photos are accurate and detailed depictions of the occurrence status and scenes of landuse maps, which makes up for the lack of ground perspective of remote sensing images. Based on semantic segmentation, this paper proposes an innovative landuse scene classification method with a deep convolutional neural network (DCNN) for ground perspective photos. The method annotates photo scenes with multi-semantic technique and determines categories of photos of landuse with semantic composition. Successfully applied in the third automatic survey of land survey photos, this method reduces the workload of manual interpretation and improved the accuracy of automatic identification of landuse scenes.

Key words: land survey, real photos, deep convolutional neural networks, multiple semantic annotations, semantic composition, land use scenario classification
