Abstract

The objective of the presented research program is to design and develop a prototype system for measuring the length of a moving log in an outdoor environment. Investigations on different sensor concepts proved the suitability of certain radar and optical solutions. The two systems, one applying microwaves and evaluating the Doppler-shift, the other using digital image processing are described in detail.
