An Ultrasonic Tree Trunk Diameter Caliper
A unique sensing system is described using an ultrasonic transducer for measuring tree trunk diameters in the orchard. Trunk diameters were calculated from the time it took sound waves to travel from the transducer to the trunk and back to the sensor. The device was calibrated with objects ranging in diameter from 1.6 (0.63 inch) to 19.0 cm (7.5 inches). The distance between the transducer and ...
متن کاملOn-the-Fly Tree Caliper Measurement - An ASABE Meeting Presentation
In fruit and shade tree nurseries, there is a need to count and measure caliper for trees frequently so as to have an accurate inventory sufficiently before harvest since disease, pests and climate can change the yield from year to year. In some tree nurseries it is common practice to count the entire stock three times a year and to caliper them once a year. Both tasks are very labor intensive,...

متن کاملEnhanced Algorithms for Estimating Tree Trunk Diameter Using 2D Laser Scanner
Accurate vehicle localization in forest environments is still an unresolved problem. Global navigation satellite systems (GNSS) have well known limitations in dense forest, and have to be combined with for instance laser based SLAM algorithms to provide satisfying accuracy. Such algorithms typically require accurate detection of trees, and estimation of tree center locations in laser data. Both...
متن کاملTrunk Diameter Fluctuation Indicators in Table Olive
2 The aim of this study was to establish threshold TGR and MDS values which could be 3 used in regulated deficit irrigation in future work. Three irrigation treatments were 4 performed during three seasons in a 37 year-old table olive orchard in Seville (Spain). 5 Control treatment was irrigated with 125% of the crop evapotranspiration. Regulated 6 deficit irrigation (RDI) treatments were perfo...
