| 中文摘要: |
| 为了提高检测效率，实现罗汉果体积自动精确测量，采用摄像机获取罗汉果个体俯视图和不同角度的4幅侧视图。通过二值化后的罗汉果俯视图计算罗汉果的圆度误差，再利用侧视图，采用有限元的方法计算罗汉果体积,并对体积进行修正。将图像测量结果与采用物理方法所测结果进行比较，结果证明此测量方法是有效可行的。这项技术可用于罗汉果及类似的农产品体积测量和包装流水线作业，还有助于实现罗汉果甜甙值的间接测量。 |

| In order to improve the detection efficiency,automatically and accurately measure the volume of siraitia grosvenorii,a camera for acquiring the top view and side view from four different angles of siraitia grosvenorii is adopted.By the binarized picture with top view,the roundness of siraitia grosvenorii and its volume are calculated by using side view depending on the finite element method,and then its volume is revised finally.The experimental results were compared with the data obtained from the physical method,and it is proved that our method is feasible and effective.This technique can be used in measuring the volume of siraitia grosvenorii or similar agricultural products for pipelining packaging,and also applied to measure mogrosides value indirectly. |
