Description

Automatic three-dimensional laser scanner for topographic mapping of water-sand physical model Technical Field The utility model relates to the technical field of three-dimensional laser scanners, in particular to an automatic three-dimensional laser scanner for mapping terrains of water-sand physical models. Background The application of automated three-dimensional laser scanners is critical to the acquisition of topographical data. However, existing automated three-dimensional laser scanners face serious terrain challenges when installed in simulated terrain at the time of experimentation. The stability of the foundation is poor due to factors such as sediment accumulation, flaccidity of the intertidal zone, periodic variation of water level, impact force caused by tides and the like existing in the estuary coastal topography of the simulated water-sand model. The complexity and the dynamics of estuary coastal topography can not be fully considered in traditional bracing piece structural design, and in soft, easy subsidence's beach or the region that receives the sea water erosion influence, the bracing piece appears the foundation easily and subsides, problem such as slope, and then leads to scanner equipment position skew, influences the precision and the reliability of survey and drawing data, probably causes the equipment damage even, has seriously restricted the high-efficient, the accurate of estuary coastal topography survey and drawing work.
