Abstract

In the last years laser rangefinder sensors have become in the focus of agricultural engineering practice and research. In the field of research, first laser rangefinders were investigated in horticulture and in agriculture. For vehicle-based determination of crop biomass, market available laser rangefinders were analysed and tested to measure above-ground biomass in oilseed rape, winter rye, winter wheat, oat, and grassland. The investigated laser rangefinder models did not fully meet the specific demands of agricultural field and crop conditions. Therefore, based on literature and own findings, in a first step newest available laser rangefinders were analysed to meet agricultural demands. A new high-end laser rangefinder scanner (ibeo-ALASCA XT) was chosen. This device was specifically developed for drivers’ assistance and autonomous guiding of road vehicles. This device was tested in 2008, focussing on the measuring properties in crop stands under field conditions. The sensor achieved very good results in repeatability of measurements. The standard deviation for the measurements of reflection height to characterise the crop height and density from a stationary vehicle in winter wheat was less than 3 mm in low, medium and high biomass areas. The low values reflect in corresponding low coefficients of variation less than 1%. The ground speed of the vehicle, ranging from 6 to 24 km/h, did not influence the readings significantly. For measurements in front of tractors and self-propelled machines (field sprayers, combine and forage harvesters) the sensor has to scan the crop stands under different inclination angles. It is shown that the inclination angle of the laser beam (varied from 10° to 80°) influences the readings significantly. Higher inclination angles result in increased reflection heights in crops. Therefore, measures are necessary to avoid or compensate these phenomena.
