Simulation and Reestablishment of the Fruit-Tree''''s Three-Dimensional Profile Surface

The methods to establish the fruit-tree's three-dimensional profile surface and the optimum spraying location of nozzles were studied.The approximate profile surface equation of fruit-tree was obtained with one image and several imsges respectively.The corresponding location surface or location spaces of nozzles were also achieved,with the spraying distance between nozzles and fruit-tree surface being optimum or suboptimum.The simulation examples were given,and the results showed that the three-dimensiolal profile surface of symmetrical fruit-tree could be reestablished with one image,and the profile surface reestablishment method with several images should be used for the dissymmetrical fruit-tree.
