Analysis of AI image recognition approach for monitoring primary school students' outdoor activity time in school

  • 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。
