Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of measurement auxiliary support, especially in a kind of three-dimensional laser scanner pedestal suitable for total station handle position. BACKGROUND

[0002] The working principle of three-dimensional laser scanner is based on laser ranging technology, which captures and reconstructs the three-dimensional topographic information of the target object through the interaction of laser beams and the surface of the target object. Specifically, the scanner is built-in laser emitter, generates a laser beam or multiple laser beams, and these laser beams are projected onto the target object surface in a specific mode through the optical system. When the laser beam irradiates the object surface, reflection or scattering phenomenon occurs, and the photoelectric transducer inside the scanner captures the reflected laser signals and converts them into electrical signals. By calculating the time difference or phase difference of the laser from emission to reception, the distance between the laser beam and the object surface can be accurately calculated. At the same time, the scanner also records the angle information of each laser point, and combined with these data, the coordinates of each laser point in three-dimensional space can be calculated using the principle of triangulation. Three-dimensional laser scanning system has a fixed space rectangular coordinate system, and for complex scene three-dimensional laser scanning, only one station cannot completely collect all three-dimensional space information of the scene, multiple stations are needed to completely reflect the scene. The target points used by the commonly used three-dimensional laser scanner are mostly specific spherical marks (spherical targets), and planar marks (planar targets) of different shapes can also be used. If you want to build a solid model, you need to convert the three-dimensional laser scanning data to the corresponding engineering coordinate system of other models, so you need to lay out a certain number of target points in the study area, and use the target point coordinates collected by the total station to calculate the coordinate conversion parameters, and finally perform coordinate conversion. When placing the target point, it should be noted that it can be recognized from multiple directions and angles, and the shielding object should be minimized, and the target point should not be placed in a straight line, which will reduce the registration accuracy during registration. Each target point should also have a certain height difference.

[0003] For complex scene survey area, the collection task is heavy, and the survey area is large, so the data collection personnel need to move a large number of stations to cover the entire survey area, which not only reduces the work efficiency, but also increases the workload. Therefore, in order to improve the work efficiency of three-dimensional laser scanner data collection, it is urgent to design a simple and practical scanner support to solve the above existing problems.
