China Patent Award

ABOUT

The China Patent Award is jointly established by the China National Intellectual Property Administration and the World Intellectual Property Organization. It is the only government award in China that specifically rewards inventions and creations for which patent rights have been granted, and it is also the highest award in China's patent field. The award mainly focuses on core technologies in key industries and critical fields, addresses "bottleneck" technical challenges, and reflects the highest level of science and technology in the industry.


The patented technology that won this award is the first to combine map projection with 3D laser scanning technology, and it is the first to propose a method for generating tunnel inner wall images using point cloud reflectance information. Combined with the method for calculating the geometric characteristics of tunnel cross-sections proposed by the Group during the same period, it forms a new adaptive comprehensive detection method for multiple types of tunnels, demonstrating remarkable novelty and inventiveness.

After years of production application and continuous research, this technology has developed into a series of effective patent portfolios, saving substantial costs compared with expensive imported detection equipment and calculation software.

At present, 3D laser scanning technology has become a major detection means in the field of rail transit structural health, driving the rapid improvement of urban rail transit operation and maintenance technology and delivering significant economic and social benefits.

In the future, SGID Group will continue to uphold the spirit of technological innovation, strengthen independent innovation, improve its technical level, and further enhance intellectual property protection and management. It will lead enterprise development through scientific and technological innovation, promote technical exchange and cooperation between industries and enterprises, better meet market demand, and drive the application and development of innovative technologies.
