摘　　要：利用机器视觉技术对鸡蛋外形尺寸进行检测,采用区域标记法分割出单个图像区域,然后确定图像区域形心点,求出其长轴、短轴和面积。研究结果表明,软件预测的鸡蛋平面投影面积(像素)长轴和短轴与实测的蛋重、长轴和短轴的相关系数分别为0.92、0.91和0.84。The method of detecting egg size by machine vision was studied. Egg image was marked by region labeling, then single region center, long axis, short axis, region area were obtained by calculating. The results showed that the correlation coefficient of real egg weight versus detected region area was 0. 92, the correlation coefficient of real long axis versus detected value 0. 91, and the correlation coefficient of real short axis versus detected value 0. 84. These results lay a solid foundation for further developing duck-egg quality detecting system.
