Abstract

The crop boundary detecting becomes more and more significant in the navigation of agricultural vehicle. In this paper, on the basis of making full use of laser ranging principle, a field information collecting system is developed, using a Sick LMS291 as the main sensor. A Kubota combine harvester plays as the platform for the system, and a VC++ program and a MATLAB program are used in data processing. A series of experiments have been conducted, and the results demonstrate that the algorithm can detect the demarcation point correctly, which provide both theoretical and practical basis for the agricultural mechanical automation.
