Precision measurement project launched in Taixing

A large-scale spatial precision measurement project developed by a team led by Wu Bin from Tianjin University was recently registered as a company and began construction in the Taixing High-Tech Zone.

Project leader Zhang Zhen said the team has worked closely with end users from the outset. As high-end equipment manufacturing has advanced rapidly in recent years, measurement demands have expanded to larger scales while requiring sub-millimeter precision.

Improving accuracy while reducing costs has been a main goal of the project. After testing thousands of approaches, the team established a new technical system. By combining the advantages of easily collimated light waves and controllable microwaves, they reduced the cost of a single device's laser component by 70 percent while achieving internationally leading ranging precision. Assembly difficulty and overall costs have also been cut by about 40 percent, paving the way for large-scale production.

The team has also independently developed a visual guidance system capable of rapidly identifying and tracking feature points in complex industrial environments. Together, these technologies create a fully integrated measurement solution.

The system has already been applied in areas such as the automatic positioning of spacecraft, structural health monitoring of large bridges, and deformation warning systems for power plant cooling towers. In shipbuilding, it has reduced the time required to align large sections from two hours to just 20 minutes.

The team is now launching research on next-generation products and plans to secure a significant share of China's high-end measurement market within the next five years.
