Abstract

The invention discloses a construction site comprehensive spatial monitoring system based on Beidou high-precision positioning and BIM. The traditional survey mode is not satisfactory in survey accuracy and efficiency for construction projects with complex topography and large construction scale. By introducing Beidou high-definition positioning into the traditional measurement technology and combining with modern wireless transmission technology, the system establishes a mm-level comprehensive measurement system at the construction site. On this basis, the BIM technology is used to compare the spatial coordinates of the design model and the construction model, so as to realize the whole process precision control and scientific deviation correction of the construction site.

Description

technical field [0001] The invention relates to a monitoring system applied to civil engineering, construction engineering and water conservancy engineering, in particular to a construction site comprehensive spatial monitoring system based on Beidou high-precision positioning and BIM. Background technique [0002] Traditional construction surveys use total stations and photoelectric rangefinders to achieve precision control of buildings. Generally speaking, in low-rise buildings or ordinary high-rise buildings, the application of traditional measurement tools can meet the design requirements. But at this stage, underground projects and super high-rise buildings emerge in endlessly, and expressways and railways are common. Without exception, the above-mentioned projects have strict requirements on measurement accuracy. However, traditional measurement technology relies on optical measurement to continuously expand the measurement range, which leads to an increase in the num...
