Child Outdoor Activity Duration Monitoring | 儿童户外活动时长监测

Using a fixed camera at the balcony door or home entrance, the system detects how many times the child enters/exits the home or balcony. With person-tracking and region-entry/exit logic, it records the timestamps of each 'leaving indoor (outdoor)' and 'returning indoor' event, and accumulates the daily total outdoor-activity duration. When the daily total falls below a preset recommendation (default: at least 1 hour of outdoor activity per day for school-age children), it outputs an 'insufficient outdoor activity' alert, suggesting parents take the child out more. Application scenarios: family parenting, child health management, schools / kindergartens. The system automatically generates daily outdoor-activity reports; if multiple consecutive days fall short, it pushes app reminders to parents. Skill features: outdoor activity is crucial for child vision protection (myopia prevention), bone development, and mental health. AI automatic monitoring helps parents objectively understand the child's outdoor situation and adjust parenting strategies. Can be integrated into smart cameras or family education apps as a practical feature for child health management. | 通过家庭阳台门或入户门口的固定摄像头，检测儿童进出家门或阳台的次数，利用人体跟踪和区域进出判定技术，记录每次离开室内（外出）和返回室内（归来）的时间点，累计每日户外活动总时长。当当日总时长低于预设推荐值（默认建议学龄儿童每天至少1小时户外活动）时，输出'户外活动不足'提醒，建议家长带孩子增加户外时间。应用场景：家庭育儿、儿童健康管理、学校/幼儿园。系统自动生成每日户外活动报告，若连续多日不足，通过APP推送提醒家长。技能特点：户外活动对儿童视力保护（预防近视）、骨骼发育、心理健康至关重要。通过AI自动监测，可帮助家长客观了解孩子户外活动情况，及时调整育儿方式。该技能可集成到智能摄像头或家庭教育APP中，成为儿童健康管理的实用功能。
