Abstract
A measurement system for the soil displacement induced by farm machinery, construction machinery, etc. has been developed by the authors. In this system movement of markers set inside the transparent side-wall of soil bin is observed, while markers follow the displacement of soil. It takes a lot of time for data processing since positions of markers are read by manual works. On-line data processing system for measurement of soil displacement was developed by adopting the high density line-shift camera and the image processing techniques. Graphic system for demonstration of trajectories of displacement, contours of strain (increment), void ratio, etc. was also developed in this present study. It was verified by the wheel traveling performance test that the system enables us to measure the soil deformation with high efficiency and accuracy.
