Description

Auxiliary data processing and real-time verification system for campus building construction paying-off Technical Field The invention relates to the technical field of digital building construction, in particular to an auxiliary data processing and real-time verification system for campus building construction paying-off. Background In campus building construction, paying-off operation is a key link for ensuring that building entities accurately fall on a design drawing. The current construction paying-off practice generally faces the comprehensive dilemma that firstly, design data (such as CAD drawing) and on-site measurement paying-off operation are in a separated state, and data flow relies on manual interpretation and conversion, so that the efficiency is low, and errors are easily introduced when a special-shaped curved surface and a dense axis net which are common in a campus building are processed. Secondly, on-site verification is delayed, the traditional method usually performs spot check after paying off is finished, process control is difficult to achieve, deviation cannot be found and corrected in real time, and in a campus construction site with a short construction period and multiple professional intersections, the deviation is easy to cause linkage problems of subsequent procedures. In addition, the instruction information is disjointed with the field environment, so that an operator can hardly intuitively and rapidly convert abstract drawing coordinates or deviation data into correct operation actions. Some existing digital measuring tools or software can locally improve efficiency, but are focused on single functions (such as data viewing or coordinate measurement only), and a complete technical chain from intelligent analysis of design data, on-site real-time closed loop verification to visual collaborative guidance cannot be formed, so that the overall intelligent level and collaborative efficiency of the campus building construction paying-off process still have great improvement space. Therefore, an integrated system capable of realizing the cooperation of design, verification and guiding depth is needed to solve the core technical problems of data splitting, control lag and non-intuitive guidance in campus building paying-off operation.
