The sand volume measurement based on the 3D la-ser scanning technology is efficient and of high-precision,but cost is high. Therefore,this paper develops the AR Geogra-phy-teaching Sandbox via the combination of the projector and Kinect v2 depth camera,providing a new solution for sand volume real-time measurement and sand scraping opera-tions. Firstly,the depth camera and projector are accurately calibrated. Secondly,the real-time measurement method of sand volume based on the triangulated irregular network mod-el is proposed. Then,the AR Geography-teaching Sandbox are used for real-time rendering and projection of sand vol-ume. Finally,a large amount of different experiments are car-ried to verify the measurement accuracy and the speed of the algorithm.
