Description

Technical Field

[0001] The present application relates to the field of paving technology, and in particular to an indoor high-precision 3D paving method. Background Art

[0002] Paving is a method of laying, usually used for laying roads, squares, sidewalks and other surfaces. In this process, the material is spread on the ground and then compacted by tools such as rollers and rollers until the surface is uniform. This method can make the ground flat, solid and beautiful. Paving is not only common in urban construction, but can also be used in the laying of floors inside buildings.

[0003] There are currently two solutions for 3D paving system elevation measurement on the market. The first is that the laser transmitter uses a domain laser transmitter, and the laser is emitted in a vertical interval, so that the 360° prism can receive laser signals in a vertical interval. The laser emission range is large, and all-round elevation detection can be achieved. The domain laser transmitter is monopolized by foreign patent technology and has a high cost of use; the second is that the laser transmitter uses an automatic total station to track the laser detector. The laser transmitter emission and reception are concentrated in one device, but multiple automatic total stations are required to achieve full laser coverage. The unit price of each automatic total station is as high as RMB 150,000, so the cost of using this solution is also relatively high.

[0004] The Chinese invention patent application with application number 2023103155982 discloses "a 3D paving control algorithm based on an automatically adjustable laser gradient and positioning system. In implementation, the laser emitter, laser detector, positioning system and azimuth measurement equipment all use universal devices. The use of universal devices ensures the low cost of the equipment. The high-precision positioning system is preferably a Beidou positioning system or a GPS positioning system. The azimuth measurement equipment is preferably a dual-antenna Beidou angle measurement device, and the intelligent host uses a mobile embedded device." The Beidou positioning system or the GPS positioning system is required for paving, so it is only suitable for scenarios that can receive Beidou or GPS satellite signals. If it is in some indoor venues with good sealing, positioning will not be possible, resulting in the inability to pave. Summary of the invention
