A stereo camera system is mounted perpendicular to the ground and height and traveled distance are calculated using normalized cross correlation. A method for evaluating the system is developed, where flower boxes containing representative surfaces are placed in a metal-working lathe. The cameras are mounted on the carriage which can be positioned manually with 0.1 mm accuracy. Images are captured every 10 mm over 700 mm. The tests are performed on eight different surfaces representing real world situations. The resulting error is less than 0.6% of traveled distance on surfaces where the maximum height variation is measured to 96 mm. The variance is measured for eight test runs, total 5.6 m, to 0.040 mm. This accuracy is sufficient for crop-scale agricultural operations.</p> World Congress on Engineering and Computer Science, October 22 - 24, 2008, San Francisco, USA http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:239515 624 Proceedings of the World Congress on Engineering and Computer Science 2008, WCECS 2008, October 22 - 24, 2008, San Francisco, USA Conference Paper Lecture Notes in Engineering and Computer Science 619 Visual Odometry System for Agricultural Field Robots 2008 2016-09-30T20:40:01Z 2457662.3611227 Visual Odometry System for Agricultural Field Robots 500 0 plainlist list 1 [[:Publications:Visual Odometry System for Agricultural Field Robots]] Visual Odometry System for Agricultural Field Robots# QUERYfa92897b51deb76dcf6a49535008dd04 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Visual Odometry System for Agricultural Field Robots# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Visual Odometry System for Agricultural Field Robots# ERRe24f17e090c98448f3de99d03182b7b6
