Abstract—An unmanned mining technology for the fully mechanized longwall face automation production is proposed and studied. The essential technology will bring the longwall face production into visualization through the VR (Virtual Reality) and AR (Augmented Reality) combination. Based on the visual theoretical model of the longwall face, the combination of virtual and reality, the real-time interactive and the 3D registration function were realized. The 3D image of the longwall face may be scaled and viewed from free angles. Using the overall affine coordinate system, the stereoscopic impression for the longwall face was enhanced; the video image is matched to 3D characteristics; the occlusion issue is resolved with the depth information solution; and the simplification visualization interactive method is proposed. The Key technology and Alpha channel are used to the combination of the real longwall face and the virtual user.
