A Design Method based on Extraction of Key Points of the Contours of Agricultural Machinery's Internal Structure-A case study on the design of a small self-propelled square baler

摘要

Refer to Reverse Engineering of extracting points cloud to generate a digital model, the paper proposes a rational method to design agricultural machinery's appearance. Depending on the product's internal structure contours, we can extract several key points and connect them by four ways: straight lines connecting, arcs connecting, free curves connecting and data fitting. Then we choose and modify the connected lines by a unified style to get the main profile of the machinery, which can better match the structural components. In the end a small self-propelled square baler's design process was presented to describe and testify the method.
