Plastic rockery has been widely used in garden landscaping art. Its phantom can be seen in theme parks, scenic spots, amusement parks, eco-tourism areas, etc., which shows its status in the current garden landscape. The plastic stone rockery has a peculiar shape and a beautiful shape, but such characteristics make its appearance uneven and extremely irregular, which makes it difficult for engineers and technicians to calculate its surface area. The commonly used formula calculation method, posting calculation method and barbed wire usage calculation method in the industry estimate its surface area. It is conceivable that the accuracy of the calculation results will be greatly reduced.

On November 11, 2021, we announced the SLAM100, our first handheld LiDAR scanner. After nearly 9 months of market testing, SLAM100 has gained a place in the fiercely competitive field of handheld lidar scanner products, and has been widely recognized by the industry, and product awareness has been effectively improved. 
At present, SLAM100 has been widely used in high-precision surveying and mapping, square calculation, forest resources census, underground space informatization, 3D real scene reconstruction and other application directions. Efficient and convenient measurement methods and relatively complete solutions.

With the rapid development of urban construction in our country, urban underground space informatization is increasingly valued by industry managers - underground space data is an indispensable and important part of urban construction, realizing three-dimensional informatization of underground space and building a three-dimensional city , providing scientific and technological support for the rational development of urban underground space resources, has become one of the most effective measures to solve urban problems. Therefore, studying high-efficiency, high-precision, and all-factor three-dimensional information acquisition and expression methods in underground space plays a crucial role in promoting urban construction and improving the level of urban informatization.
