Cao Hui’s educational research

The main teaching situation is "Digital Photogrammetry", undergraduate students "Photogrammetry Algorithm Design", the main research direction of graduate students. Since joining the work in 1985, he has participated in and been responsible for more than 20 projects and topics, and has won national scientific and technological progress. 1 second prize, 1 first prize for scientific and technological progress in surveying and mapping, and 3 second prizes for scientific and technological progress in surveying and mapping. He has successively participated in the "Analytical Transformation of Analog Mapping Instrument B8S", "Computerized Transformation of Analytical Mapping Instruments BC1, BC2 Series, P3, C100 Series", "Development of Domestic Digital Photogrammetry System VirtuoZo", and Final Assembly of the National Bureau of Surveying and Mapping. Topics include "Three-dimensional imaging technology for key targets", "Development of intelligent aerial triangulation software", "Development of digital photogrammetry grid DPGrid software". In the 863 major project outsourcing project "Fast Stitching of Aerial Imagery and DEM Production for Geophysical Exploration Applications", we have integrated the aerial photography system, aerial LIDAR and the aerial geophysical prospecting system to obtain terrain data while acquiring aerial geophysical prospecting data. and surface image data, thereby simultaneously providing terrain and surface feature information for aerial geophysical exploration. Its product forms mainly include Digital Elevation Model (DEM) and Digital Orthophoto (DOM). At the same time, it provides professional products such as survey line sections, strip orthophotos, and three-dimensional strip maps according to the needs of geophysical operations to provide projects with The party responsible has solved the key technical problems in the application of LiDAR data in geophysical prospecting. In the 863 key project topic "Emergency Response Technology Based on Multi-Source Remote Sensing Imagery" hosted by him, after the occurrence of sudden disasters such as remote earthquakes and floods, the massive unconventional aerial photography data obtained by multiple sensors can be quickly and efficiently processed. Rapid processing (including frame-based aerial images and three-line array remote sensing images), and the ability to generate surveying and mapping products and three-dimensional landscapes in a timely manner, provide timely, accurate, and reliable spatial data for disaster relief operations, and formulate reasonable rescue plans in a timely manner.

Main awards, honors and academic part-time awards: won the second prize of the National Bureau of Surveying and Mapping’s Science and Technology Progress Award in 1986, won the first prize of the State Bureau of Surveying and Mapping’s Science and Technology Progress Award in 1997, and won the second prize of the National Bureau of Surveying and Mapping’s Science and Technology Progress Award in 1999
