A system for managing the progress of construction based on lidar technology

A system for managing the progress of construction based on LiDAR technology, comprising a cloud server and a handheld measurement device;

• the handheld measurement device is provided with a LiDAR and a positioning device;
• the system is used to monitor the construction progress of the building which includes the following steps:
• S1. enter the building with the handheld measurement device, measure the building using the LiDAR of the handheld measurement device and record the measurement data, and the positioning device records the positioning data of the measurement location;
• S2. The handheld measurement device transmits the measurement data and positioning data in real time to the cloud server, which records the measurement data, positioning data and measurement time;
• and according to the positioning data, it retrieves, the historical measurement data recorded at the same position is retrieved and compared with the real time measurement data to generate the comparison result data.
• S3. The server transfers the comparison result data in real time to the handheld measurement devices to show the comparison result data through the display devices for augmented/mixed reality display.
