自然环境下果实定位的误差修正方法研究

【摘要】 对用双目立体视觉技术来测定番茄果实空间位置中存在的误差原因进行了分析,提出采用神经网络的方法对误差进行修正,建立网络模型和训练系统,并对测试样本进行仿真实验。实验结果表明,绝对误差可以控制在0～5mm之间,达到了收获机器人定位精度的要求。更多还原

【Abstract】 The causes of errors existing in the measurement of threedimensional coordinates of the tomato with the help of binocular vision technology are analyzed.Then it is pointed out that the errors can be amended by means of building a neural net model and a corresponding training system. A simulation experiment is also carried out on the test sample. The experiment indicates that the errors can be controlled in the range of 0 -5 mm, thus meeting the requirement for positioning of robots harvesting fruits.更多还原
