基于视频跟踪的竖缝式鱼道内鱼类运动行为分析

THE ANALYSIS OF FISH MOVEMENT BEHAVIOR IN VERTICAL SLOT FISHWAY BASED ON VIDEO TRACKING

摘要: 竖缝式鱼道过鱼对象运动行为与鱼道池室内水力条件是否相适应是进行鱼道设计的关键。研究通过视频跟踪法对竖缝式鱼道中目标鱼的运动轨迹进行实时跟踪, 获取鱼的运动加速度、运动速度, 并和人工手动跟踪的鱼类运动轨迹进行对比, 证明基于视频跟踪法的鱼类运动分析程序既能较好的应用于竖缝式鱼道中, 获取鱼类运动行为, 又可减少大量的人工操作, 有助于为竖缝式鱼道设计提供重要基础数据。

Abstract: The fish movement behavior and hydraulic condition in fishway are suitable, which is the key of designing vertical slot fishway. In this paper, using video tracking method of computer technology obtain fish movement trajectory, swimming acceleration, swimming velocity. Compared to manual tracking analysis method, the method of video tracking can effectively obtain fish movement behavior, which can reduce manual operation and provide important basis data for vertical slot fishway design.
