A lightweight cloud-edge registration framework is designed and can be used in image geolocation tasks based on portable devices. This method can effectively optimize the initial pose and improve the registration accuracy of visual sensors in digital city scene. Compared with the existing methods, the position and orientation errors are reduced by 35.9% and 39.3%. Experiments show that this method achieves accurate registration of virtual and real images with large differences in appearance. Firstly, the virtual perspective image of digital city scene is obtained, the plumb line which contains structural semantic information is extracted from the target image, and the properties of global constraints of the plumb line is used to restore the camera's position accurately and achieve the registration of monocular image in the virtual digital scene. In order to improve the accuracy of visual sensor spatial registration in digital city scene, this paper presents a method of virtual-real registration for digital city scene with structural semantic information in urban area. Therefore, the accuracy of outdoor 6 Degree of Freedom (DOF) position obtained by existing methods is usually insufficient, resulting in low registration accuracy of the visual sensor. However, in digital city applications, seasons and weather always change, there are often large differences in appearance between the real image taken by visual sensor and the image of virtual scene.
Due to the popularity of vision sensors, vision-based registration methods have been widely used.
Currently, the spatial registration methods for visual sensors can be divided into hardware-based and vision-based methods. It is one of the key technologies for applications such as Augmented Reality and Video GIS. The purpose of spatial registration for visual sensor is to estimate or optimize the position and orientation of the visual sensor and to get the accurate spatial position of any object in the image. The key to digital city application is registering the visual sensors with virtual 3D model accurately. Visual sensor is an important sensor type which is widely used in urban life, such as surveillance cameras, vehicles, and other devices. The integration of spatial data volume and object-linked perception data is the key to digital city applications. Digital city usually uses the 3D model of the real scene as the spatial data volume and integrates the object-linked data of various sensors to achieve virtual-real fusion. 关键词: 数字孪生城市, 实景三维, 虚实融合, 视觉传感器, 地理配准, 视觉地理定位ĭigital city is one of the main requirements of three-dimensional (3D) real scene and leads the direction of future smart city construction.
