Abstract: To solve the problem that traditional natural gas pipeline mapping equipment can only map straight pipelines with close distances, a dual-robot pipeline mapping method based on laser ranging is proposed. Pipelines are divided into the horizontal straight pipeline section, the 90° horizontal bent pipeline section, the uphill/downhill pipeline section and the composite pipeline. In this method, the two vehicles move alternately at a uniform speed from the entrance to the exit of the pipeline. Through calculating the distance data captured by the robots, the 3-D model of each section can be obtained. Finally the mapping result of the whole pipeline can be spliced by each section. The experiment results show that this method can map different pipelines, and increase the mapping distance effectively: the distance error in 2000m is within 4m and the error rate is about 0.178%.
