yolov7也是一款非常出众的目标检测模型，在我之前的文章中也有非常详细的教程系列的文章，感兴趣的话可以自行移步阅读即可。

《基于YOLOV7的桥梁基建裂缝检测》

《YOLOv7基于自己的数据集从零构建模型完整训练、推理计算超详细教程》

《基于YOLOv7融合轻量级网络MobileOne的表格检测识别分析系统》

《助力安全作业生产，基于YOLOv7融合Transformer开发构建安全帽检测识别分析系统》

《助力不文明行文识别，基于YOLOv7融合RepVGG的遛狗牵绳行为检测识别分析系统》

学生课堂行为检测是一个比较有实际意义也比较有趣的应用场景，在我之前的一些文章中也有过相关方面的实践如下：

《基于yolov5轻量级的学生上课姿势检测识别分析系统》

《基于轻量级CNN开发构建学生课堂行为识别系统》

《yolov4-tiny目标检测模型实战——学生姿势行为检测》

可以看到：这里模型选用的大都是yolov5及之前的系列模型，对于新款模型的使用则有所欠缺。

这里主要就是基于yolov7来开发构建学生课堂行为检测识别分析系统，首先看下效果图：

如果对yolov7的使用有问题可以看我超详细的教程：

接下来简单看下数据集情况：

数据来源于真实场景拍摄录制采集。

标注文件如下：

实例标注内容如下所示：
