He has been engaged in teaching and scientific research in geographic information system, intelligent transportation and 3S integration for a long time. Instructed more than 50 graduate students and more than 20 doctoral students. He has presided over more than 30 scientific research projects such as the 863 Program, key projects of the National Natural Science Foundation and general projects of the National Natural Science Foundation. As the project leader, he completed the 973 plan "Research on Basic Science Problems of Traffic Congestion Bottlenecks in Big Cities". At present, he is in charge of the research work of the 973 plan project "Theory and method of digital protection of cultural heritage".
Presided over the development of "unmanned smart car", "LD laser scanning measurement system", "vehicle-mounted multi-sensor integrated intelligent pavement detection system" and "large laser dynamic deflection measurement system" with independent intellectual property rights, as well as software and hardware systems such as vehicle navigation and location service, vehicle monitoring and mobile asset management, and pavement information management; The key technologies and industrialization problems such as multi-sensor synchronization and integrated control, multi-source data fusion processing and analysis, and continuous measurement of pavement deflection are solved. The industrialization of research results has remarkable economic and social benefits.
He has published nearly 400 academic papers, 5 monographs, registered software copyright 13 and applied for 9 patents; "Spatial information network service technology and its industrialization" won the second prize of the National Science and Technology Progress Award (second place), "Key technology and application of integrated modeling of three-dimensional complex space objects" won the first prize of the National Ministry of Education (first place), "Vehicle-mounted pavement rapid detection and measurement system" won the first prize of the Ministry of Education (first place) and "Key technology and application of network navigation and logistics distribution in complex dynamic traffic environment" won the first prize of China Geographic Information Technology Progress Award (first place).
