Recently, information from the State Intellectual Property Office shows that Ningbo Shanghang Surveying and Mapping Co., Ltd. has applied for a patent named "An Automatic Recognition System for Pipeline Shallow Profile Images Based on Deep Learning". This patent can effectively improve the accuracy and efficiency of automatic recognition of pipeline shallow profile images. Ningbo Shanghang Surveying and Mapping Co., Ltd. was founded in 1997. In 2022, it was listed among the fourth batch of specialized, sophisticated, distinctive, and novel "little giant" enterprises, becoming the first enterprise in the surveying and mapping field in the city to receive this honor. Accurate to 2 Centimeters Qiantang River Bridge is the first double-deck railway and highway bridge designed and built by China itself. With this pioneering achievement, it has become a Chinese landmark and is also listed as a national key cultural relics protection unit. In 2021, Ningbo Shanghang Surveying and Mapping Co., Ltd. participated in projects such as the flaw detection and scanning of the piers of Qiantang River Bridge. The survey team used 3D sonar and multi-beam bathymetry technology, combined with a fully automatic unmanned survey vessel for operation. It only took more than 10 hours to complete the on-site data collection, with extremely high efficiency. After data collection, the company used digital methods to precisely detect the damage points and cracks of the underwater piers. The previous manual underwater probing method had significant safety risks, but now it has been replaced by this digital method, which greatly improves the safety factor of the operators. The collected data, after post-processing, generates 3D visual images of the piers. These images can clearly show every detail with an accuracy of centimeter level, providing strong big data support for the protection of Qiantang River Bridge. In terms of historical building surveying and mapping, Ningbo Shanghang Surveying and Mapping Co., Ltd. is a pioneer in the surveying, mapping, archiving, and safety inspection of historical buildings in Ningbo. It took the lead in using the operation mode of fusing airborne lidar with ground 3D laser scanning to realize air-ground integrated joint surveying and mapping. This innovative surveying and mapping method combines the advantages of both air and ground, improving the comprehensiveness and accuracy of surveying and mapping. It is worth mentioning the surveying and mapping accuracy. The accuracy of a single station surveying and mapping is as precise as 2 millimeters, and the overall surveying and mapping accuracy of a single historical building is accurate to 2 centimeters. Such high accuracy ensures the reliability and accuracy of the surveying and mapping data, and can provide detailed and precise information for the protection and renovation of historical buildings. Building a Solid Safety Defense Line In August last year, the survey site of Ningbo Beilun Reservoir Ship Lock was extremely hot. Four surveyors from Ningbo Shanghang Surveying and Mapping Co., Ltd. were busy working on-site under the high temperature. They were carefully setting up a precision desktop surveying device, with beads of sweat rolling down their foreheads, but their focused expressions never slackened. This device is no ordinary one. It is equipped with beam and 3D laser scanning technology. It is like a loyal guardian of the reservoir and ship lock, always paying attention to every change here. In engineering construction and maintenance, it is the cornerstone of precise monitoring and safety guarantee, providing solid data support for the smooth progress of the entire project. Ningbo Shanghang Surveying and Mapping Co., Ltd. has been monitoring Ningbo Beilun Reservoir for more than 9 years. Over these long years, traditional surveying and mapping technologies have been continuously updated and iterated. The company keeps up with the pace of technological development and actively introduces high-tech surveying and mapping technologies such as drones, unmanned ships, and multi-beam systems. The application of these new technologies makes the survey work more efficient and accurate, and also provides stronger guarantee for the safe operation of the reservoir and ship lock. The monitoring system established by the company uploads various data such as water level, water flow speed, and structural stress of the reservoir and ship lock in real-time through a multi-layer sensor network. At the same time, it combines AI technology to conduct in-depth analysis and accurate prediction of these data. Using AI algorithms, the system can quickly identify abnormal situations in the data and issue early warnings in a timely manner. This series of operations has greatly improved the security and reliability of the data, allowing staff to grasp the operation status of the reservoir and ship lock in a timely manner. Supported by 50 Patents Innovation is the primary driving force leading enterprise development. Ningbo Shanghang Surveying and Mapping Co., Ltd. deeply understands this, based on the surveying and mapping field, and actively jumps out of the limitations of traditional surveying and mapping. The company starts from multiple aspects such as talents, equipment, technology, and qualifications to continuously expand its development advantages. In terms of talents, it attracts and cultivates professional surveying and mapping talents; in terms of equipment, it keeps updating; in terms of technology, it actively explores the frontier; in terms of qualifications, it strives to upgrade, laying a solid foundation for the long-term development of the company. Up to now, Ningbo Shanghang Surveying and Mapping Co., Ltd. has achieved fruitful innovation results. It has accumulatively obtained 7 invention patents, 9 software copyrights, and 41 utility model patents. These achievements are a strong proof of the company's innovation strength, adding a powerful weight to the company's competition in the surveying and mapping industry.
