Abstract

The trowel is a construction machinery used for slurry lifting and trowelling cement concrete surfaces. The machine is noisy and has certain dangers during operation. This paper focuses on the automatic operation of the trowel and takes the driving hydraulically driven trowel as the research platform. According to the overall requirements of automatic operation, with the stereo visual-inertial navigation system as the core, a positioning system and a full coverage path planning scheme are designed. The real data was collected in the test site for the experiment, and the results show that the stereo visual-inertial navigation system can provide the required positioning accuracy for the trowel.
