After obtained the bachelor’s degree and master’s degree in 1985 and 1988 from Wuhan Technical University of Surveying and Mapping, I came to the University of Tokyo in 1993 for Doctor research and got a PhD in engineering in 1996.
My main research interests focus on providing advanced technologies and solutions for realizing safe, secure, comfortable, smart and eco cities with the fusion of technologies of GIS (Geographic Information System), RS (Remote Sensing), GPS (Global Positioning System), IOT (Internet of Things), AI (Artificial Intelligence) and so on.
(1) Research on Mobile Mapping System (MMS) development
(2) Research on fusion of stereo images and laser data
(3) Research on algorithm development for automatically extracting houses and road traffic signs from stereo images
(4) Research on development of GPS-Supported Visual SLAM
(5) Research on development of remote sensing data fusion technologies for automatic classification and feature recognition
(6) Research on smart agriculture and smart city |
| Research Field(Keyword & Summary) |
- (1) GIS Data acquisition and processing
The technology and fusion processing algorithm based on multi-sensor data collaborative collection such as inertial navigation system, panoramic camera and laser scanner are proposed, which realizes the rapid positioning, automatic registration and accurate recognition of ground objects of multi-sensor data. This achievement is at the world's leading level, and the technology system developed has been widely used in smart agriculture construction, smart city road and streetscape data collection, and automatic driving information acquisition.
- (2) GPS-Supported Visual SLAM
A framework for GPS-supported visual Simultaneous Localization and Mapping with Bundle Adjustment (BA-SLAM) using a rigorous sensor model in a panoramic camera was proposed in this research. The rigorous model does not cause system errors, thus representing an improvement over the widely used ideal sensor model. The proposed SLAM does not require additional restrictions, such as loop closing, or additional sensors, such as expensive inertial measurement units
- (3) Remote sensing data fusion
Accurate crop distribution maps provide important information for crop censuses, yield monitoring and agricultural insurance assessments. Most existing studies apply low spatial resolution satellite images for crop distribution mapping, even in areas with a fragmented landscape. Unmanned aerial vehicle (UAV) imagery provides an alternative imagery source for crop mapping, yet its spectral resolution is usually lower than satellite images. In order to produce more accurate maps without losing any spatial heterogeneity, this study fuses Sentinel-2A and UAV images to map crop distribution at a finer spatial scale in an experimental site with various cropping patterns.
