Cut Crop Edge Detection Using A Laser Sensor, Santosh Pitla, Joe D. Luck, Scott A. Shearer
Cut Crop Edge Detection Using A Laser Sensor, Santosh Pitla, Joe D. Luck, Scott A. Shearer
Department of Biological Systems Engineering: Conference Presentations and White Papers
An off-the-shelf low cost laser sensor was tested and evaluated both in laboratory and field conditions. The sensor identified the angular and straight edges of the laboratory test surface and replicated the straight edge profile with an error of 4%. In field conditions, the sensor identified three types of cut crop edges (wheat, alfalfa and corn) and replicated distinct shapes (triangle, curved and rectangular edges). The sensor was tested at two sensor path offset distances and three tractor/sensor speeds (3.2, 6.4 and 9.6 km/h). In all test runs the sensor detected the cut-crop edges. Standard deviations and RMSE values in …

Guidance Directrix Generation Using Laser Sensors, Santosh Pitla, Joe D. Luck, Scott A. Shearer
Department of Biological Systems Engineering: Conference Presentations and White Papers
A sensor array consisting of two laser sensors was utilized to determine the guidance directrix (offset distance-d, heading angle-ø) that are required as reference inputs for an automated guidance system. The sensor array was evaluated in both laboratory and field conditions. Under laboratory conditions the sensor array replicated the physical profile of the target surface with a 4% error in determining the heading angle. Field tests were conducted in two types of crops; corn and alfalfa. The sensor array identified the cut-crop edge profile ahead of the tractor and replicated distinct shapes of the cut-crop edge. RMSE values in determining …
