This paper proposes a block erection technique based on digital measurement to apply the digital measurement technology to block erection.The real-time monitoring and early warning system adopted by the technique can bring about distance measurement with high accuracy and stability,and generate the view of relative position and attitude between the actual block and the base model with fast calculation of multiple objective point data,laser distance measurement and attitude measurement,thus realizing the data collection,analysis and simulation during the block erection.Meanwhile,it makes the monitoring process more intuitive with human-computer interaction,integration of software and measurement system,and integration of software and simplified model to realize the real-time display of measurement data,calculation result and 3D model simulation.The digital analysis and visualization operations can assist the positioning operator on site to guide the erection process,so as to realize the real-time position monitoring of block erection,shorten the work period,reduce rework rate and improve the erection efficiency.
