Fish Isolation / Schooling Behavior Detection | 鱼类聚集/离群行为识别
v1.0.0Through fixed cameras on aquariums, the system continuously tracks the 2D position of each fish in the school, computes the school centroid (center of mass), and measures the distance from each fish to the centroid (in units of fish body length). When a fish drifts more than 10 body lengths away from the school center and the state lasts longer than 1 hour (or a user-defined threshold), the system outputs an 'isolation behavior' alert. This skill helps early detection of bullied, sick (e.g. parasites, bacterial infections), spawning-period solitary or environment-distressed (e.g. strong water flow, temperature gradient) individuals, prompting aquarists to inspect and intervene. Application scenarios: home aquariums, public aquariums, aquaculture ponds, quarantine tanks. The system monitors continuously and pushes reminders when prolonged isolated fish is found. Skill features: prolonged isolation is often an early signal of disease (e.g. external parasites, digestive issues) or stress from bullying. AI-based automatic identification of isolation behavior helps aquarists detect sick fish early and isolate for treatment, reducing whole-tank infection risk. This skill can be integrated into smart aquarium cameras to enhance product behavior-analysis capability. | 通过鱼缸固定摄像头，持续跟踪鱼群中每条鱼的二维位置，计算鱼群中心（质心），并检测每条鱼与中心的距离（以鱼体长为单位）。当某条鱼偏离鱼群中心超过 10 倍体长，且持续时间超过 1 小时（或用户设定阈值）时，输出'离群行为'提示。该技能有助于早期发现被欺凌、生病（如寄生虫、细菌感染）、产卵期孤立或环境不适（如水流过强、温度不均）的个体，提醒养鱼者及时检查干预。应用场景：家庭鱼缸、水族馆、水产养殖池、检疫缸。系统连续监测，当发现长期离群鱼只时推送提醒。技能特点：鱼只长期离群往往是疾病的早期信号（如体表寄生虫、消化问题），或受欺凌导致应激。通过 AI 自动识别离群行为，可帮助养鱼者及早发现病鱼并隔离治疗，降低全缸感染风险。该技能可集成到智能鱼缸摄像头中，提升产品行为分析能力。
