基于Python的图像处理技术在鱼类尺寸测量中的应用

Application of Image Processing Technology Based on Python in Fish Size Measurement

在渔业养殖中,鱼的生长情况是养殖阶段所关注的重要指标。而深水网箱养殖,养殖平台远离海岸且置于海面下,养殖人员必须远赴养殖平台现场查看,使得时刻掌握鱼的生长情况十分困难。文章提出一种基于Python图像处理技术的鱼类尺寸测量方法。利用深水养殖平台中的相机拍摄回传来获取现场的原始图像,调用OpenCV库函数对原始图像进行去除噪声干扰、增强鱼体特征等预处理步骤,然后通过Canny算子进行边缘检测提取鱼体轮廓,再通过最小外接矩形函数算法计算出鱼长。测试结果与真实尺寸对比,误差控制在5%以内,且检测速度高,可满足实时检测的要求,实现深水网箱信息化养殖。

The safe production of agricultural machinery is an important guarantee to promote the stable and high-quality development of agriculture and maintain the safety of farmers'lives and properties,at the same time,it is of great significance to speed up the development of modern agriculture.It analyzes the problems existing in the safety production management of agricultural machinery,and puts forward some measures and suggestions to strengthen the safety production management of agricultural machinery.
