Description

Building mapping method, system, computer equipment and storage medium
Technical Field
The invention relates to the technical field of building mapping methods, in particular to a building mapping method, a system, computer equipment and a storage medium.
Background
Building mapping methods are used for measuring and drawing buildings through specific technologies and tools to acquire accurate data and image information of the buildings. The main purpose of the method is to collect the spatial and geographical information of the building, including the size, shape, position and the like of the building, and record and analyze the characteristics of the building. Through the building mapping method, the effects of building planning and design, construction and engineering management, building change and repair and the like can be realized. The purposes of surveying and mapping are generally achieved by means of ground measuring instruments, remote sensing, unmanned aerial vehicles, laser scanning, indoor laser scanning and the like, so that accurate and detailed building data are provided, and support and guidance are provided for links such as building design, construction and management.
In building mapping methods, existing methods typically rely on a single data source only, often on satellite images or ground-captured pictures only, which results in data incompleteness and inaccuracy. The existing method is often not fine enough in data processing, and computer vision and image processing technology cannot be fully utilized to preprocess the data. Existing methods typically do not employ machine learning and deep learning algorithms, resulting in poor accuracy and efficiency of feature extraction. The existing method generally fails to fully utilize radar technology and point cloud processing algorithms, so that the reconstructed three-dimensional model is not accurate enough. Existing methods typically analyze only a single aspect of the building, such as only structural stability, and ignore other important aspects of energy consumption, efficiency of use, etc., resulting in a single-sided comparison of the end results.
