Development and Application of 3D Laser and Sonar Integrated Scanner for Karst Fine Detection
In order to achieve precise detection and 3D digitization of karst,this paper developed a set of 3D scanning equipment which integrates laser and sonar scanning technology into the same set of equipment.The scanning mode of this device can automatically switch between laser scanning in anhydrous environments and sonar scanning in water-filled environments.Accurate measurement of the internal morphology of karst is achieved through layer by layer automatic scanning,and a three-dimensional model is constructed by using the results of two-dimensional scanning.The size,shape,and direction of karst can be accurately calculated which can provide reliable basic data for engineering design,construction,and evaluation.
