Stereo vision-based measurement device for construction inspection
A measurement device for fast dimensional inspection in construction industry is designed and developed based on stereo vision. Two high-resolution cameras based on 13MP image sensor are used in this device. A variety of invariant detectors and descripters are used for image matching. The measurement error for 200 mm baseline is less than 1 mm within a range of 5 m. A prototype has been developed and tested in real construction sites.

Three-Wheeled Omnidirectional SLAM Robot
A three-wheeled omnidirectional SLAM robot is designed and developed independently. The core of the robot is a NVIDIA Jetson Nano with a Robot Operating System (ROS) wrapper—
Melodic—over the Ubuntu 18.04 OS. The SLAM algorithms are implemented in the Jetson Nano including mapping and localization.

Real-time visual SLAM robot
A real-time visual Simultaneous Localization And Mapping (SLAM) robot is built utilizing a RGB-D camera. The core of the robot is a NVIDIA Jetson TX1 with a Robot Operating System (ROS) wrapper-Indigo-over the Ubuntu 14.04 OS. The robot maps its location based on its surroundings using ORB-SLAM, with loop detection and re-localization capabilities.

Vision-based automatic cutting robot
A cutting robot for underground drainage pipe is designed to automatically reopen the lateral connection between main pipe and branch pipe after CIPP (Cured-in-Place-Pipe) installation.The robot can recognize the target cutting area by vision, and localize it by visual control and distance measurement.
