ABSTRACT

SLAM (Real-time Positioning and Map Construction) technology has a good application in mobile mapping, relying on inertial navigation technology, three-dimensional model construction. The integrated surveying and mapping of real estate is often complicated with tasks, large coverage area, high technical requirements and time consuming. The application of SLAM technology has the advantages of high efficiency and high precision. It does not need to mark a large number of GPS signals of ground object points, and effectively solves the problem that the area obscured by aerial survey cannot be interpreted. Combined with the relevant requirements of rural real estate surveying and mapping, this paper conducts rural real estate surveying and mapping through 3D SLAM handheld 3D laser scanner, and discusses its value and adaptability in rural real estate surveying and mapping. SLAM (Simultaneous Localization and Mapping) Real-time positioning and map construction: it can move from an unknown location in an unknown environment, position itself according to the environmental characteristics and map in the process of moving, and obtain three-dimensional spatial data on the basis of its positioning to make an incremental map and complete the map construction. Rapid and accurate positioning can be realized in closed space, and it is widely used in underground space positioning and modeling [1]. This paper discusses the application of 3D SLAM technology in rural real estate integration project, through the measurement examples, analysis of the measurement accuracy and error, and compared with the traditional measurement method, reduce the complexity of measurement, make the working efficiency has a significant increase, its use in the rural real estate surveying and mapping has a certain value and adaptability.
