Abstract

A novel technology called visual robotic arm aided laser standoff methane sensing is proposed in this paper for intelligent inspection of gas pipeline leakage. It mounts a homemade miniaturized laser methane sensor to the end of a robotic arm and uses a depth camera to guide the laser towards the target pipeline. By improving Yolov5s, real-time high-precision identification of pipelines was achieved with an accuracy rate of 99.5%. Collaborative work is achieved through hand eye calibration. The system able to locate leaks at a distance of 3m with an error of approximately 30mm.
