Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a slope setting out system and a side slope setting out method. Background technique [0002] Traditional RTK (Real-Time Kinematic) geodetic receivers use satellite navigation technology to achieve high-precision positioning of measurement points. It has been used in slope measurement. However, the prior art relies on the use of design drawings in conjunction with a calculator to calculate the coordinates of the design, and then stake out the coordinates on the spot. In this way, due to the need to constantly check the drawings and use the calculator to calculate in the field stakeout, the stakeout efficiency is very low. [0003] Therefore, there is an urgent need in this field to develop a new slope stakeout system and method that is simple to operate and has high stakeout efficiency. Contents of the invention [0004] The purpose of the present invention ...
