摘要
对工厂化水产养殖来说,生产过程中的活鱼分级、分塘环节十分关键,非接触式、无伤害一直是追求的目标。通过数字图像处理技术,得到窄体舌鳎扁平面不规则图像并测算了其面积。采用一元线性回归模型,分析了鱼的重量和扁平面面积的关系,实验结果表明,二者存在着一定的线性关系,相关系数为0.3807。下一步的研究需要考虑到不同生长阶段的舌鳎鱼体厚度等因素影响,找出二者之间更准确的模型关系,为非接触式测量重量和分级提供支持。
For aquaculture, the classification of live fish and the deconcentrition of fish into more ponds are very important process. Non-contact and no-harm are always the target of this process. Using the technology of digital image processing, the binary irregular image of cynoglossus gra- cilis is got and measured. We analyze the relationship between the weight of fish and flat surface area by a linear regression model. The experi- mental results show that two parameters has a certain linear relationship, and the correlation coefficient is 0. 380 7. Further research is needed to account for the effects of different growth stages of cynoglossus gracilis body thickness and other factors, and a more accurate model is needed to identify the relationship between the two parameters, to provide support for the non-contact measurement of weight and classification.
