果树三维外形轮廓的仿真与重建

根据检测到的果树二维图像,建立了果树三维外形轮廓和喷头定位曲面.利用拍摄到的1个或有限个二维图像,经坐标变换得到近似的果树外形轮廓,以及与果树外形轮廓相对应的喷头定位曲面.通过具体的仿真算例,表明对于比较对称的果树,由1幅图像就可得到其精确的外形轮廓,而由多幅图像建立果树外形轮廓的方法则适用于不对称的果树.

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.
