| description | With the continuous advancement of urbanization, the demand for comprehensive monitoring of diverse suburban areas is increasing, which simultaneously raises the need for high-precision positioning technologies especially for the automatic positioning for video surveillance imagery. The current challenges in high-precision positioning for surveillance data include: (1) The difficulty of matching wide-angle images; (2) The significant scale differences between Tower-mounted Video Surveillance (TVS) and Remote Sensing (RS) ortho-images complicate multi-scale automatic focusing; (3) The positioning accuracy decreases due to the physical factors in suburban scene areas. To address these issues, this study proposes a Dual-Feature Image Matching-based Method for High-Resolution RS and TVS Collaboration method for precise positioning in complex suburban areas, referred to as DFMC. Through the processes of geo-referencing, dual-feature image matching, homography transformation and geographic coordinate computation, the proposed DFMC overcomes the challenges of high-precision matching between wide-angle video images and RS images, facilitating the projection of any point coordinates from the pixel coordinate system of TVS frames to the projected Cartesian coordinate system of RS ortho-images. Experiments are conducted using over 28,000 video frames of tower-mounted surveillance system across 210,000 km<sup>2</sup> in Hunan Province of China. The results indicate the proposed DFMC achieves a positioning accuracy error of less than 1.5 meters in flat areas and less than 3 meters in complex suburban areas. Therefore, DFMC enables rapid monitoring and positioning in complex suburban areas, providing valuable informational support for relevant authorities. |
