摘要

摘要: 目的研究开发一种可以长期持续动态监测学生户外活动时长的方法, 为户外活动时长与学生健康的关系等研究方向提供数据支撑。方法于2022年4月28日至7月6日抽取深圳市某小学1 168名学生纳入研究对象, 利用布设在学校教室、走廊和关键路径等顶部的固定摄像头, 智能识别画面内学生数据和时长, 利用AI云计算等方法, 统计学生非在教室时间替代户外活动时间。结果 24个试点班级平均在校户外活动时长为67.6~113.0 min, 各年级平均每人在校户外活动时长呈现逐年级下降趋势(F=42.74, P < 0.05);学生户外活动时长与近视、超重检出率呈负相关(r值分别为-0.74, -0.45, P值均 < 0.05)。结论 AI图像识别监测的户外活动时长数据基本符合监测点实际情况, AI图像识别监测学生在校户外活动时间的方法具有可行性和推广性。

Abstract: Objective To develop a method that can continuously monitor duration of students' outdoor activities for a long time, so as to provide data support for the relationship between outdoor activity duration and students' health. Methods From April 28 to July 6, 2022, 1 168 students from a primary school in Shenzhen were selected. Fixed cameras were placed on the top of school classrooms, corridors and critical paths were used to identify student data and duration in the picture. And AI, cloud computing and other methods were used to measure students' non-classroom time instead of outdoor activity time in school. Results The average length of time spend on outdoor activities in school of the 24 pilot classes were 67.6-113.0 min, and showed a downward trend by grade (F=42.74, P < 0.05). The duration of outdoor activities among students was negatively correlated with the detection rate of myopia and overweight(r=-0.74, -0.45, P < 0.05). Conclusion The data on outdoor activity time calculated by AI image recognition is basically in line with the reality. Monitoring students' outdoor activity time at school through AI image recognition is feasible and popularized.
