The invention provides a scanning method, device and system based on a total station, and relates to the technical field of total station scanning. The method comprises the following steps: establishing a theoretical model database; collecting feature points capable of defining geometric features of the to-be-measured entity through the total station, and obtaining measurement data of the geometric feature points of the to-be-measured entity; and fitting the measurement data of the geometric feature points of the to-be-measured entity with the corresponding theoretical model database to determine the spatial position information of the nodes of the to-be-measured entity. According to the technical scheme, the theoretical model database is established, the total station is used for collecting the feature points capable of defining the geometric features of the to-be-measured entity, and the measurement data of the geometric feature points of the to-be-measured entity and the corresponding theoretical model database are fitted to determine the spatial position information of the nodes of the to-be-measured entity. According to the method, the high efficiency of total station measurement and the precision of three-dimensional laser scanning are both achieved, the timeliness of measurement can be guaranteed, the control measurement efficiency is greatly improved, and then the overall construction efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of total station scanning, in particular to a scanning method, device and system based on a total station. Background technique [0002] Steel structures are widely used in civil engineering, and the control points of its precision are not only in the processing and installation stage, but also the control of measurement precision is very important. At present, the usual method is the measurement scheme of total station plus self-adhesive reflector, and sometimes three-dimensional laser scanning is also used. [0003] Three-dimensional laser scanning has obvious advantages in obtaining measurement data in a certain area, and the obtained data is usually a massive point cloud data on the order of millions or more. It has obvious advantages in the application of virtual assembly and docking. However, the accuracy is limited by the brightness and distance of the environment, and the instrument is required to b...
